CDC: 2009 H1N1 Flu: Situation Update 30 October 2009

2009 H1N1 Flu: Situation Update

October 30, 2009, 1:30 PM ET

Key Flu Indicators

October 30, 2009, 1:30 PM
Each week CDC analyzes information about influenza disease activity in the United States and publishes findings of key flu indicators in a report called FluView. During the week of October 18-24, 2009, a review of the key indictors found that influenza activity continued to increase in the United States from the previous week. Below is a summary of the most recent key indicators:
  • Visits to doctors for influenza-like illness (ILI) increased steeply since last week in the United States, and overall, are much higher than what is expected for this time of the year. ILI activity now is higher than what is seen during the peak of many regular flu seasons.
  •  
  • Total influenza hospitalization rates for laboratory-confirmed flu are climbing and are higher than expected for this time of year. Hospitalization rates continue to be highest is younger populations with the highest hospitalization rate reported in children 0-4 years old. 
  •  
  • The proportion of deaths attributed to pneumonia and influenza (P&I) based on the 122 Cities Report has increased and has been higher than what is expected at this time of year for four weeks now. In addition, 22 flu-related pediatric deaths were reported this week; 19 of these deaths were confirmed 2009 H1N1, and three were influenza A viruses, but were not subtyped. Since April 2009, CDC has received reports of 114 laboratory-confirmed pediatric 2009 H1N1 deaths and another 12 pediatric deaths that were laboratory confirmed as influenza, but where the flu virus subtype was not determined.
  •  
  • Forty-eight states are reporting widespread influenza activity at this time. They are: Alabama, Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin, and Wyoming. This many reports of widespread activity are unprecedented during seasonal flu.
  •  
  • Almost all of the influenza viruses identified so far are 2009 H1N1 influenza A viruses. These viruses remain similar to the virus chosen for the 2009 H1N1 vaccine, and remain susceptible to the antiviral drugs oseltamivir and zanamivir with rare exception.

Certain US states could run out of hospital beds for H1N1 Flu second wave

Certain US states could run out of hospital beds for H1N1 Flu second wave

CHICAGO, Oct 2 — Fifteen states could run out of hospital beds and 12 more could fill 75 per cent of their beds with H1N1 sufferers if 35 per cent of Americans catch the virus in coming weeks, a report released yesterday said.

The study, based on estimates from a computer model developed by the US Centres for Disease Control and Prevention, shows the strain hospitals and health departments could face as a second wave of H1N1 surges.


“Our point in doing this is not to cry Chicken Little but really to point out the potential even a mild pandemic can have and how readily that can overwhelm the healthcare delivery system,” Jeffrey Levi, director of Trust for America’s Health, which sponsored the report, said in a telephone briefing.
According to the report, the number of people hospitalised could range from 168,025 in California to 2,485 in Wyoming, and many states may face shortages of beds.

Some may need to cut back on hospitalisations for elective procedures.

“States around the country will also have to figure out how to manage the influx of people in doctors’ offices and ambulatory care settings, in addition to the surge in hospitalisations,” Levi said.

He said state and local health departments are scrambling to set up distribution systems for the H1N1 vaccine as it becomes available this month, but challenges remained.

“These systems are untested, and glitches are sure to arise along the way,” Levi said.

Local health authorities are especially worried about reaching young people, who traditionally are not vaccinated for flu, and minorities, who were harder hit by the swine flu in the spring.

While the federal government will pay for the vaccine itself, Levi said, it was not yet clear how the actual cost of giving the shot will be financed.

Although many public and private insurance plans have said they will cover it, others have not yet agreed.

“This could become a huge burden for state and local health departments, or become a dangerous disincentive for people to get a vaccine,” he said.

The 35 per cent attack rate used in the report is based on the 1968 flu pandemic, which was considered mild. It assumes an outbreak would last around eight weeks.

Levi said the number was consistent with World Health Organisation statements predicting that up to a third of the world’s population will become sick with the new H1N1 virus that was declared a pandemic in June.

The President’s Council of Advisors on Science and Technology said in August that 1.8 million Americans may need to be hospitalised and around 30,000 could die, assuming a 30 per cent infection rate. — Reuters

US Flu patterns suggest new A/H1N1 spike over summer months and rising...

US data shows that the 2009 A/H1N1 flu virus has become the dominant flu virus causing influenza-like-illness (ILI)
ILI report rates have increased over the seasonal pattern, with a possibility of higher escalation recently after week 33.
Clearly the H1N1 flu has caused a new spike in ILI (purple bars) over the summer months, way over the usual seasonal pattern (green bars).

H1N1 Update: CDC Issues Guidance for Early Childhood Programs

Featured in Journal Watch: Antivirals Slightly Shorten Duration of Seasonal Flu in Children
H1N1 Update: CDC Issues Guidance for Early Childhood Programs
The CDC has issued guidance to help reduce the spread and severity of influenza among children in early childhood programs and their providers.
Based on the severity of 2009 H1N1 influenza so far, recommendations include:
  • Children and staff in target vaccination groups should be immunized.
  • Those with flu-like illness should stay home until they've been without fever for 24 hours (without using fever-reducing medications).
  • Child care providers should check staff members' and children's health daily, and separate ill individuals from others until they can be sent home.
  • Treatment within 48 hours of illness onset should be encouraged for those at high risk for flu complications.
If influenza severity increases, additional strategies include:
  • Children with ill household members and high-risk staff should be allowed to stay home.
  • People with flu-like illness should remain at home for at least 7 days after symptom onset.
  • Program closures should be considered.

Technical Report for State and Local Public Health Officials and Child Care and Early Childhood Providers on CDC Guidance on Helping Child Care and Early Childhood Programs Respond to Influenza during the 2009–2010 Influenza Season

September 4, 2009, 9:00 AM ET
CDC is releasing new guidance to help decrease the spread of influenza (flu) among children in early childhood programs and early childhood providers during the 2009–2010 influenza season. 
The new guidance expands upon earlier guidance documents by providing a menu of tools that health officials and early childhood providers can choose from based on conditions in their area. 
The new guidance recommends actions to take now, during the 2009–2010 flu season; suggests additional strategies to consider if CDC determines that flu is becoming more severe; and provides a checklist for decision-making at the local level. 
Based on the severity of 2009 H1N1 flu-related illness thus far, this guidance recommends that children and early childhood providers with influenza-like illness remain home until 24 hours after resolution of fever without the use of fever-reducing medications. 
For the purpose of this document, “early childhood” will refer to both center-based and home-based early childhood programs, Head Start programs, and other early childhood programs providing care for children in group settings. The guidance applies to all early childhood programs, even if they provide services for older children.

This Technical Report provides explanations of the strategies presented in the CDC Guidance on Helping Child Care and Early Childhood Programs Respond to Influenza during the 2009–2010 Influenza Season and suggestions on how to use these strategies.

The guidance is designed to decrease exposure to seasonal flu and 2009 H1N1 flu and limit the disruption of the essential service early childhood provides to families.
According to the National Association of Child Care Resource and Referral Agencies (NACCRA) Adobe PDF fileExternal Web Site Icon, there were 119,174 child care centers and 238,103 home-based child care programs in the United States in 2008 . Of the 9,660,666 (39.5%) children 0 through 4 years of age in (non-relative) child care for at least 10 hours each week identified in the 2007 National Survey of Children’s Health, 10.6% were in child care in their own home, 21.7% were in child care in someone else’s home, and 72.0% were in center-based child care.

Among all age groups, children less than 5 years old had the highest 2009 H1N1 hospitalization rates and the second-highest 2009 H1N1 incidence rates during April 15–July 24, 2009. Children less than 5 years of age also have high hospitalization rates for seasonal flu; the risk for severe complications from seasonal flu is highest among children less than 2 years of age.  

Importantly, infants less than 6 months of age represent a particularly vulnerable group because they are too young to receive the seasonal or 2009 H1N1 influenza vaccine; as a result, individuals responsible for caring for these children constitute a high-priority group for early vaccination.

Other groups at higher risk for complications of flu include pregnant women and people of any age with certain medical conditions such as diabetes, heart disease, asthma, and kidney disease. Visit http://www.cdc.gov/h1n1flu/qa.htm for more information.

Influenza vaccination is the primary means of preventing flu but infection control measures also can reduce the spread of flu. Early childhood settings present unique challenges for infection control because of the close interpersonal contact, shared toys and other objects, and limited ability of young children to understand or practice good respiratory etiquette and hand hygiene. Thus, parents, early childhood providers, and public health officials should be aware that, even under the best of circumstances, transmission of infectious diseases such as flu cannot be completely prevented in early childhood or other settings. No policy can keep everyone who is potentially infectious out of these settings.

The purpose of this document is to provide updated guidance for reducing the spread of influenza in early childhood settings. We provide recommendations assuming that the severity of illness through the 2009–2010 flu season is similar to what was seen during the spring and summer of 2009, as well as recommendations that could be applied if the severity of illness worsens. Influenza is unpredictable and it is possible that the upcoming fall and winter flu season may be more severe than during the spring and summer.
 
CDC will provide periodic updates of assessments on the spread of flu, the severity of the illness it is causing (including hospitalizations and deaths), and possible changes in flu viruses; if the information CDC gathers indicates that flu is causing more severe disease than during the spring/summer 2009 H1N1 flu outbreak, or if other developments indicate more aggressive mitigation measures should be taken, CDC may recommend additional strategies. Also, because conditions may vary from community to community, early childhood providers should also look to their state and local health officials for information and guidance specific to their location.

Recommendations for early childhood programs for the 2009–2010 influenza season

The most important things early childhood providers can do to reduce the risk of influenza in the early childhood setting are to encourage influenza vaccination for those recommended for vaccination; encourage and facilitate use of hand hygiene and respiratory etiquette measures by children and staff; ensure that ill children and adults do not come to the facility; and separate ill and well people as soon as possible. The following recommendations provide a framework to determine the most appropriate and feasible strategies for each early childhood setting.

Early childhood providers should examine and revise, as necessary, their current crisis or pandemic plans and procedures, including updating contact information for families and staff. Plans should be shared with families, staff, and the community before an outbreak so that they know how and when they will be contacted and what types of information to expect. Early childhood providers should be proactive, develop contingency plans to cover for staff who are absent from work, and regularly remind parents and staff of exclusion policies. Early childhood providers should review – and revise, if necessary – their sick leave policies to remove barriers to staff staying home while ill or to care for a family member.

A doctor’s note should not be required for children or staff to validate their illness or to return to the early childhood setting. Doctor’s offices and medical facilities may be extremely busy and unable to provide such documentation in a timely way during an influenza outbreak. Planning should also include determining quantities of supplies and space needed to facilitate respiratory etiquette and hand hygiene (for example, tissues, soap, and paper towels).

Early childhood providers should frequently remind children, their families, and staff about the importance of staying home when ill; early treatment for people at higher risk for flu complications; hand hygiene; and respiratory etiquette. Educational materials (for example, posters) to enhance compliance with recommendations should be visible throughout the early childhood setting. Examples of these materials are available at http://www.cdc.gov/h1n1flu/flyers.htm.
The recommendations that follow are divided into two groups: 1) recommendations to use now, during the 2009–2010 flu season, assuming that the severity of influenza in the fall and winter will be of similar severity to that seen during spring and summer 2009, and 2) recommendations to consider adding if a more severe flu season occurs.  

Recommended strategies to use now, for flu conditions with similar severity to spring/summer 2009

Vaccination

The best way to protect against the flu is to get vaccinated each year. A vaccine will be available this year, as it is each year, to protect against seasonal influenza. Groups that should be vaccinated against seasonal influenza include: everyone 6 months through 18 years of age; all people 50 years of age and older; women who will be pregnant during flu season; people age 18 through 49 with certain medical conditions that put them at higher risk of complications from influenza; healthcare workers; and household contacts and caregivers of people who are at increased risk of severe illness from influenza, including children less than 5 years of age, pregnant women, persons 65 and older, and anyone with certain medical conditions. Seasonal influenza vaccine usually becomes available early in the fall.

Vaccine to protect against the 2009 H1N1 flu virus is currently in production, and initial doses are expected to become available later in the fall. CDC’s Advisory Committee on Immunization Practices (ACIP) has recommended that initial doses of the 2009 H1N1 flu vaccine be prioritized for five target groups: pregnant women, people who live with or care for children younger than 6 months of age, healthcare and emergency medical services personnel, people age 6 months through 24 years, and people age 25 through 64 years who have certain medical conditions that put them at higher risk of complications from influenza. Children and many staff in early childhood settings fall within these groups and should be among the first to receive the 2009 H1N1 flu vaccine. For more information on the ACIP recommendations, visit http://www.cdc.gov/mmwr/pdf/rr/rr58e0821.pdf Adobe PDF file

Stay home when sick with influenza-like illness

CDC recommends that children and caregivers with flu-like illness remain at home and away from others until at least 24 hours after they are free of fever (100° F [37.8° C] or greater when measured orally), or any signs of a fever, without the use of fever-reducing medications. Epidemiologic data collected during spring 2009 found that most people with 2009 H1N1 flu who were not hospitalized had a fever that lasted 2 to 4 days; this would result in an exclusion period of 3 to 5 days in most cases.  

Early childhood programs, parents, or state and local officials may elect to require longer exclusion periods. Parental or community concerns and preferences also should be considered when evaluating if a more stringent exclusion policy is appropriate. Early childhood programs are encouraged to work with their local health department to establish exclusion policies.
The symptoms of 2009 H1N1 flu virus can include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue, and sometimes diarrhea and vomiting. Young children with influenza may be cranky, less playful, or not feed well. Infants with influenza may have fever and lethargy without cough or respiratory symptoms. For more information, visit http://www.cdc.gov/h1n1flu/childrentreatment.htm.  

During flu season, early childhood providers should be particularly careful to ensure that children and staff with flu-like illness are excluded from the early childhood setting for the recommended time period. Sick persons should stay at home until the end of the exclusion period and avoid contact with others to the extent possible, except when necessary to seek required medical care. CDC recommends this exclusion period even if antiviral medications are administered. Visit http://www.cdc.gov/h1n1flu/guidance/exclusion.htm for more information on staying home while ill.

Fever-reducing medicines (medicines containing acetaminophen or ibuprofen) can be used by people with flu-like illness. Ibuprofen should not be given to infants younger than 6 months of age. Persons less than 18 years of age with flu should not take aspirin (acetylsalicylic acid) because doing so can cause a rare but serious illness called Reye’s syndrome. Children less than 4 years of age should not be given over-the-counter cough and cold medicine without first speaking with a pediatric health care provider. View more information on caring for sick persons.

Conduct daily health checks

Early childhood providers should perform a daily health check of children and staff. Early childhood providers should have a policy and process for performing a daily health check of all children upon or soon after arriving at the program. The purpose of the health check is to observe and briefly assess the child’s overall health. This health check should consist of direct observation of the child and talking with the parent or guardian and the child. During the day, staff also should identify children and other staff who may become ill. Ill children and staff should be further assessed by taking their temperature and inquiring about symptoms. An example of how to perform daily health checks can be found at: http://www.bmcc.edu/Headstart/Trngds/Diseases/pg91-108.htmExternal Web Site Icon.

Early childhood providers should regularly update parent contact information so that parents can be reached quickly if they need to pick up their ill child. Caring for Our Children: National Health and Safety Performance Standards: Guidelines for Out-Of-Home Child CareExternal Web Site Icon provides more information on health checks.

An early childhood program’s health consultant may provide additional assistance. Some center- and home-based early childhood programs have access to a health consultant who is qualified to provide advice on child care. Early childhood programs should contact their State Child Care Administrator or local child care resource and referral agency for information on the availability of early childhood health consultants in their local area. Visit http://nrckids.orgExternal Web Site Icon for more information on health consultants.

Separate ill children and staff

Children and staff who appear to have a flu-like illness upon arrival should be sent home. Children who develop symptoms of flu-like illness while at the early childhood program should promptly be separated from other children and staff until the parent or guardian arrives to take the sick child home. While this may be challenging for some home-based providers, they should provide a space where the child can be comfortable and supervised at all times.
 
Early childhood providers who care for persons with known, probable, or suspected influenza or flu-like illness may consider wearing appropriate personal protective equipment. When caring for an ill infant or young child, the caregiver should try to position the child’s head to minimize the child’s coughing directly into the faces of others, if possible. Visit: http://www.cdc.gov/h1n1flu/masks.htm or www.flu.govExternal Web Site Icon for more information on personal protective equipment and how to recommend it to employees.

Ill persons should be placed in well-ventilated areas where at least 6 feet of distance can be maintained between the ill person and others. Early childhood programs should designate such an area in advance. This area should not be one commonly used for other purposes, such as the playroom or a space through which others regularly pass. This area should be child-proofed and children should receive appropriate and safe supervision there. A limited number of staff should be designated to care for ill children until their parents arrive. These should be people who are not at high risk of flu complications (for example, pregnant women or persons with chronic medical conditions).

Staff who develop symptoms of flu-like illness while at the early childhood program should be separated from children and other staff and promptly sent home. When possible, and if the sick staff member can tolerate it, he or she should wear a surgical mask when near other persons. Visit: http://www.cdc.gov/h1n1flu/guidance_homecare.htm for information on caring for a sick person.

Hand hygiene

Children and staff should be encouraged to wash their hands often with soap and water, especially after coughing or sneezing. Because it will never be possible to identify everyone who is potentially infectious, hand hygiene is of critical importance. Hand sanitizers should primarily be used as an optional follow-up to traditional hand washing with soap and water. Some early childhood settings prohibit the use of alcohol-based hand sanitizers because of concerns about their toxicity if ingested. If alcohol-based products are not allowed, other hand sanitizers that do not contain alcohol may be useful. However, hand sanitizers should not be used when hands are visibly soiled.  

Early childhood providers should provide adequate time for all children and staff to wash their hands. Parents and early childhood providers should wash the hands of children who cannot yet wash themselves and closely monitor children who have not mastered proper hand hygiene. This could include children with special physical or developmental needs, particularly those with limitations or developmental delays in self-care skills. Soap, water, and paper towels are critical for proper hand hygiene and should be readily available. In addition, early childhood providers also should educate families, children, and staff about the importance of good hand hygiene and proper methods for hand hygiene. Visit: www.cdc.gov/cleanhands for more information on hand hygiene.

Respiratory etiquette

Cover the nose and mouth with a tissue when coughing or sneezing and throw the tissue in the trash after use. Influenza viruses are thought to spread mainly from person to person in respiratory droplets, which are often distributed by coughs and sneezes. Hands should be cleaned promptly after coughing or sneezing. Children should be taught developmentally appropriate respiratory etiquette (for example, coughing or sneezing into an elbow, arm, or sleeve if they are not able to retrieve tissues in sufficient time). To encourage respiratory etiquette, children, and staff should have easy access to tissues and trash receptacles and be educated about the importance of respiratory etiquette, including keeping hands away from the face. Visit: http://www.cdc.gov/flu/protect/covercough.htm for more information on respiratory etiquette.

Routine environmental cleaning

Early childhood providers should regularly clean all areas with a particular focus on items that are more likely to have frequent contact with the hands, mouths, and bodily fluids of young children (for example, toys and play areas). These areas and items also should be cleaned immediately when they are visibly soiled. CDC does not believe any additional disinfection of environmental surfaces beyond the recommended routine cleaning is required.

Some states and localities have laws and regulations mandating that specific cleaning products be used in early childhood settings. Early childhood providers can contact their state or local health department or department of environmental protection for additional guidance. Early childhood providers should ensure that custodial staff and others in the early childhood setting who use cleaners or disinfectants read and understand all instruction labels and understand safe and appropriate use. Instructional materials and training should be provided in languages other than English as locally appropriate.

Early treatment for children and staff at high-risk for flu complications

Influenza can cause serious complications, including bacterial pneumonia and dehydration, and can worsen chronic medical conditions, such as congestive heart failure, asthma, or diabetes. People should know before an outbreak begins if they or a member of their family are in a high-risk group. Parents and staff should be encouraged to talk with their health care provider to determine if they or a member of their family are at higher risk for influenza complications. Groups that are at increased risk of complications from influenza if they get sick (high-risk groups) include: children younger than 5 years old; people aged 65 years or older; children and adolescents (younger than 18 years) who are receiving long-term aspirin therapy and who might be at risk for experiencing Reye’s syndrome after influenza virus infection; pregnant women; adults and children who have asthma, other chronic pulmonary, cardiovascular, hepatic, hematological, neurologic, neuromuscular, or metabolic disorders, such as diabetes; and adults and children with immunosuppression (including immunosuppression caused by medications or by HIV). People 65 years and older, however, appear to be at lower risk of 2009 H1N1 flu infection compared to younger people. But, if older adults do get sick from influenza, they are at increased risk of having a severe illness.

Parents of children under age 5 and staff at high risk for flu complications who develop flu-like illness should call their health care provider as soon as possible to determine if they need antiviral treatment. Early treatment (within 48 hours of the onset of illness) with antiviral medications can reduce the severity and duration of influenza illness and can decrease the risk of severe illness. CDC recommends that early childhood providers encourage ill staff at high risk for flu complications and the families of ill children to seek early treatment. People on antiviral treatment may still shed influenza viruses and transmit the virus to others. In addition, people taking antiviral medications can develop infection with antiviral resistant virus strains. To lessen the chance of spreading influenza viruses that are resistant to antiviral medications, people on antiviral treatment should stay at home and away from others as recommended and practice good respiratory etiquette and hand hygiene even after their fever has resolved. Visit: http://www.cdc.gov/h1n1flu/recommendations.htm for more information on antiviral medications.

Selective early childhood program closures

Consider selectively closing early childhood programs if flu transmission is high in the community.  Because children less than 5 years of age are a group at high risk for flu complications, some communities may consider temporarily closing some early childhood programs with the goal of reducing the spread of flu among these children. The decision to selectively close a early childhood program or part of a program (for example, the infant room) should be made locally and should balance the risks of keeping the children in the program with the social and economic disruption that can result from closing early childhood programs. Early childhood officials should work closely with their local and state public health officials when deciding whether or not to selectively close an early childhood program or part of a program. Additional considerations about early childhood program closures are provided in the next section.

Recommended strategies to add in the event of increased severity compared to spring/summer 2009

CDC may recommend additional strategies to help decrease the spread of flu if global, national, or regional assessments indicate that flu is causing more severe disease. In addition, state and local health officials may choose to use additional strategies. Although the following strategies have not been scientifically tested in early childhood settings, they are grounded on basic principles of infection control. Implementation of these strategies is likely to be more difficult and to have more disruptive effects than the previously described strategies. These strategies should be considered if influenza severity increases and are meant for use in addition to the strategies outlined above.

Permit high-risk staff to stay home

If flu severity increases, staff at high risk for flu complications (for example, pregnant women or persons with high-risk medical conditions) may consider staying home while influenza transmission is high in their community. Such people should make this decision after consulting with their health care provider. People who elect to stay home should also attempt to decrease their exposure in other ways – for example, by avoiding large public gatherings.

Pregnant women are at high risk for severe complications from 2009 H1N1 flu and may choose to withdraw their children from early childhood programs or to refrain from working as early childhood providers if flu severity increases. In addition, early childhood program staff with family members who are at high risk for flu complications should consult with their health care providers about whether they should refrain from working as early childhood providers during this period. 

Increase social distances between children in the early childhood environment

If influenza severity increases, early childhood providers should explore innovative methods for increasing social distances or separating children into small groups (without allowing the children to mix between groups) within the early childhood environment. This is not a simple or easy strategy for many early childhood programs, especially home-based programs. Implementing any of the following options would require considerable flexibility. Early childhood programs may wish to consider the following options:
  • Avoiding bringing groups of children from different classes together.
  • Keeping caregivers with their same class and minimize reassignments so teachers and children are kept as a cohort and to reduce contact between classes.
  • Postponing trips that bring children together from multiple classrooms in large, densely packed groups.
  • Conducting activities outdoors.
  • Dividing classes into smaller groups for example, group with 6 or fewer children.
  • Moving indoor play areas farther apart.
  • Moving groups to larger spaces, when available, to allow more space between children.

Children with ill household members should stay home

If flu severity increases, children who live with people with flu-like illness should remain home for 5 days from the day the first household member gets sick. This is the time period they are most likely to get sick themselves. The greatest risk of transmission is during the first 5 days of illness of the first ill household member (about 90%), with the largest transmission risk by Day 1 of this person’s illness (about 40%). Keeping all the children in the household at home during this time period may also keep the flu virus from being spread to others outside the home. If a household member develops an acute respiratory illness during this time, the recommendations for exclusion of persons with flu-like illness should be implemented. The five-day period does not need to start again for other well children in the household.

Extended exclusion period

If flu severity increases, persons with flu-like illness should remain at home for at least 7 days, even if symptoms resolve sooner. Individuals who are still sick 7 days after they become ill should continue to stay home until at least 24 hours after symptoms have resolved. This recommendation is based on data for seasonal flu infection indicating that influenza virus shedding generally lasts for 5 to 7 days after symptom onset, but can be longer in young children or among people with weakened immune systems. A longer period of exclusion also may be considered on the basis of setting and population-specific characteristics. Visit: http://www.cdc.gov/h1n1flu/guidance_homecare.htm for more information on caring for sick persons in the home.

Early childhood program closures: reactive and preemptive

If flu severity increases, CDC recommends that communities review and prepare to implement their early childhood program closure plans according to the guidelines outlined below. Early childhood and health officials should balance the risks for flu transmission in their community with the disruption that early childhood program closures would cause. Early childhood providers should work closely and directly with their local and state public health officials to make sound decisions on the basis of local conditions, and to implement strategies in a coordinated manner.

When communities choose to close early childhood programs, early childhood and public health officials should clearly tell parents and their communities the reason for closing these programs.
 
Reactive closure might be appropriate for the following reasons: when early childhood programs are experiencing excessive absenteeism among children or staff; when a large number of ill children are being sent home each day; or for other reasons that decrease the ability of the early childhood program to function. Early childhood programs provided by few providers will be more susceptible to reactive closures because illness in a single provider could make the early childhood program inoperable. 

Preemptive closures may be considered to decrease the spread of flu virus among children and early childhood program staff, and in the larger community. If global or national risk assessments indicate an increased level of severity compared with the spring 2009 H1N1 flu outbreak, CDC might recommend closing early childhood programs.

Early childhood program closure is likely to be more effective at decreasing the spread of influenza virus in the community when used early in relation to the appearance of the virus in the community and when used in conjunction with other strategies (for example, cancellation of community sporting events and other mass gatherings). Cancellation or postponement of community events is a decision for event organizers, local public health officials and other government agencies to make and should be part of a coordinated community process. CDC does not believe any additional disinfection of environmental surfaces beyond routine cleaning is required while an early childhood program is closed.

A vaccine for 2009 H1N1 flu should become available in fall 2009. Protective immunity will likely require 2 doses of vaccine, separated by at least 3 weeks and requiring 2 weeks after the second dose for the immune response to fully develop (that is, a minimum of approximately 5 weeks after the first vaccination for full protection to develop). If an increase in community-wide transmission occurs before vaccine-induced immunity is anticipated, communities whose goal is to substantially reduce influenza transmission among children in early childhood programs may consider temporarily closing these programs. Infant rooms may need to close longer as infants under age 6 months cannot receive flu vaccine.  
Resuming early childhood programs after closure
The length of time an early childhood program should be closed will vary depending on the type of early childhood program closure and the severity and extent of illness. When the decision is made to close an early childhood program, CDC recommends doing so for 5–7 calendar days. Reactive early childhood program closures are likely to be of shorter duration than selective or preemptive closures.

On a regular basis (for example, weekly), public health authorities in jurisdictions where early childhood programs have closed should reassess the epidemiology of the disease, the benefits of keeping children home, and the societal repercussions of closing these programs. On the basis of this reassessment, public health authorities, in consultation with early childhood providers, may decide to extend the early childhood program closure or to reopen them. In the event that CDC recommends preemptive early childhood program closure, this recommendation also might include a modification to the suggested length of closure, on the basis of the severity observed across the nation and globally. Therefore, early childhood providers may have to plan for more prolonged periods of closure.
Reducing adverse effects from early childhood program closure
As part of a community planning process, early childhood program closure plans should address possible secondary effects on the community. Plans should be developed and communicated to all community members affected by early childhood program closure. Preparing to address these secondary effects may increase acceptability and participation in early childhood program closure.
Early childhood program closure may:
  • Affect critical infrastructure
  • Adversely affect parents’ job security
  • Cause income loss for parents and early childhood providers
  • Cause long-term loss of early childhood programs
  • Reduce early childhood program quality by forcing experienced staff into other jobs
  • Cause deterioration in child nutrition from the loss of access to the meals program in early childhood programs
  • Decrease educational progress of the children enrolled in early childhood programs, and
  • Decrease child safety from possibly increased use of unregulated and marginal child care by parents unable to find or afford quality care.
Parents should start thinking about options for alternate child care in case their usual programs or schools are closed because these closure decisions may be made very quickly. Alternate arrangements include care by relatives, neighbors, coworkers, friends, or making accommodations to work settings to allow for parents to work from home, if possible, or to have different working hours to allow for parents to care for the children at home.

Roles

Collaboration is essential. Many different stakeholders have important roles to play in the decision-making process, implementing strategies, and ensuring their effectiveness. To be most effective, these activities must be coordinated at the federal, state, and local levels.
  • Early childhood programs should
    • Work with state and local public health and education agencies to decide which strategies to implement and when, to collect and share data on absenteeism, and to disseminate emerging guidance.
    • Encourage the routine use of a qualified early childhood health consultant – a licensed health professional such as a nurse with experience working on health issues in out-of-home child care.
    • Encourage recommended seasonal flu vaccination and when it becomes available, the 2009 H1N1 flu vaccine.
    • Examine and revise as necessary current crisis or pandemic plans and procedures, including updating parental contact information and communicating plans to parents.
    • Examine and revise as necessary the current sick leave policy for staff to allow them to stay home when ill.
    • Encourage parents to develop backup alternate child care plans if a severe influenza outbreak causes dismissal of the early childhood program.  
    • Serve as a resource for families to help them understand:
      • The signs and symptoms of flu.
      • The risks associated with flu and the strategies they can use to decrease their risk.
      • What families can do to decrease the spread of the flu virus and their role in keeping early childhood programs open.
      • Other resources in their community that might be able to provide assistance in addressing the secondary effects of early childhood program closures.
      • Who should receive the seasonal flu and 2009 H1N1 flu vaccines and how to get them.
  • It is important for parents to be responsible for keeping ill children at home, practicing hand hygiene and respiratory etiquette, teaching and monitoring children’s hand hygiene and respiratory etiquette, and planning in advance for alternate child care placement in the event that their usual program or school must close or limit the number of children.
  • Early childhood program staff should stay at home when ill, practice hand hygiene and respiratory etiquette, and teach and monitor children’s hand hygiene and respiratory etiquette when possible.
  • Early childhood program administrators need to establish alternate staffing plans to provide care while staff are absent from work.
  • Private sector support is essential for working parents and guardians who need to stay home to care for an ill child or to find alternate child care if their usual early childhood program closes, even temporarily. The economic impact of early childhood program closure can have serious effects throughout the community and local economy. 
  • Community-based organizations can provide crucial support to families by providing meals, transportation, and possibly alternate child care sites for small groups of children (for example, groups of 6 or fewer children). They may also be able to provide other services to ease the burden of early childhood program closure

Determining community approaches to protecting children and staff in early childhood programs

To decrease exposure of children and early childhood providers to the flu virus, CDC recommends a combination of targeted, layered strategies applied early and simultaneously on the basis of trends in the severity of the disease, characteristics of the virus, expected impact, feasibility, and acceptability. These issues should be determined through collaborative decision making involving early childhood and public health agencies, parents, health care providers, and the community.

CDC and its partners will continuously look for changes in the severity of influenza and will share what is learned with state and local agencies. States and local communities can expect to see significant variability in disease burden across the country.

Every community has to balance a variety of objectives to determine the best course of action to help decrease the spread of influenza. Decision-makers should explicitly identify and communicate their objectives, which might be one or more of the following: (a) protecting overall public health by reducing community transmission; (b) reducing transmission among children and staff in early childhood programs; and (c) protecting people with high-risk conditions. Some strategies can have negative consequences in addition to their potential benefits. The following questions can help begin discussions and lead to decisions at the community or state level.

Decision-makers and stakeholders

In your community, are all the right decision-makers and stakeholders involved in the decision-making process?

  • Identify the decision-makers. In different jurisdictions, local and state health, education, and homeland security agencies may have relevant decision-making responsibilities. States and localities also have early childhood licensing agencies, Child Care Administrators, and Head Start Collaboration Directors. Direct involvement of governors, mayors, public health officials, education administrators, and early childhood business owners and administrators may be needed.

  • Identify the stakeholders. Stakeholders will vary from community to community but may include parent representatives, local businesses, corporate early childhood program officers, center-based and home-based program owners and operators, early childhood staff, health care providers, hospitals, community organizations, and local resource and referral agencies.

  • What is the process for working together?

    • Do you have a process for regular input and collaboration on decisions?
    • Are there strong, open communication channels between public health officials, health care providers, and early childhood administrators? Does this include frequent information sharing?
    • Do you regularly review your crisis and pandemic plans? Do you revise them as needed?
    • Are community members engaged in making decisions regarding health and safety?

    Information collection and sharing

    Can local or state health officials determine, interpret, and share information with other local or state decision-makers about the following?

    • Does the local or state government have a designated early childhood health consultant who can coordinate communication about flu?
    • What is the severity and extent of spread of the disease in the state or locality? How many people are making outpatient visits for influenza-like illness? How many people are being hospitalized for influenza-like illness? Are the numbers of hospitalizations or deaths increasing? What percent of these hospitalized patients require admission to intensive care units? How many influenza deaths have occurred in the community? Are some groups becoming ill, or more severely ill, than others?
    • How busy are local health care providers and emergency departments? How many visits are they getting for flu-like illness? Are they able to meet the increased demand for care from people with flu-like illness? Are local health care providers or emergency departments becoming overburdened?
    • Are the hospital and intensive care unit (ICU) beds full with flu patients? Is there available space in the ICUs? Are there enough ventilators?
    • Do the hospitals have enough staff to provide care? Is there increasing absenteeism in health care workers due to influenza-like illness in themselves or their family members?
    • Is there enough antiviral medication in the community to treat ill patients at high risk for complications?
    • What are the plans for seasonal and 2009 H1N1 vaccination clinics?

    Can early childhood program providers collect and share information with state or local decision makers about the following?

    • How many children and staff are absent due to flu-like illness?
    • How many children with flu-like illness symptoms are being sent home every day?

    Feasibility

    Does the state or community have the resources to implement the strategies being considered?

    • What resources are available? Do you have access to the funds, personnel, equipment, and space needed?
    • How long will the strategies take to implement? How long can the strategies be sustained?
    • Are changes to legal authority or policy needed? How feasible are these changes?
    • How can you most clearly communicate with the community about steps parents, children, and families need to take and the reasons for recommendations?

    Acceptability

    Has the state or community determined how to address the following challenges to implementing the strategies?

    • How are public concerns affecting the community? What can you do to empower personal responsibility for protective actions?
    • Will the community support the strategies under consideration? What can you do to increase support?
    • What secondary effects (e.g., impaired child nutrition, job security, financial support, health service access, and educational progress) might result from the strategies under consideration? Can you get the message out to businesses and employers that they need to have flexible leave policies that align with public health recommendations?
    • Can these secondary effects be mitigated? Which community entities and organizations can help reduce the secondary effects?
    • What can be done to increase community acceptance?

    NY Times review: Seeking Lessons in Swine Flu Fight

    Seeking Lessons in Swine Flu Fight

    New York Times: August 10, 2009





    Much about the swine flu pandemic and the virus remains unknown...

    • This outbreak exposes many weaknesses in world’s ability to respond to the sudden emergence of a widespread illness.
    • Over all, the pandemic’s severity is considered as “moderate” compared with past influenza pandemics, but the WHO says, it's spread with “unprecedented speed” > 168 countries.
    • Typically flu strikes in colder months, but the swine flu virus, A(H1N1), has swept through summer camps in the United States and Canada.
    • Belief that many more people will get swine flu than seasonal influenza this fall and winter, but outbreaks of both strains possible, perhaps at different times.
    • One weakness -- despite years of planning -- the infrastructure of health departments in many countries, including the United States, is inadequate (in varying degrees) to deal with the sudden appearance of a new strain of influenza.
    • Also, the number of beds in hospital intensive-care units and emergency rooms is limited, as is equipment like mechanical respirators to help patients breathe when the virus attacks the lungs.

    Another problem is communication, journal reports still lacking...

    • Officials and experts say much have been learned about A/H1N1 influenza.
    • But relatively little information, including periodic summaries of what has been learned since beginning of pandemic, has been reported and published.
    • Some said researchers waiting to publish in journals, which can take months or longer.
    • Journals impose severe penalties for disclosing information before publication, although they say they exempt matters of public health importance.
    • Whatever the reason, delays in reporting such information can hamper plans for public health responses.

    Unusual Presentation of A/H1N1 flu hamper quicker diagnosis/management...

    Dr. Wenzel, a former president of the International Society for Infectious Diseases, said he had observed a broad spectrum of illness from human swine influenza: people who experienced few or no symptoms to those who rapidly developed complications and died.

    • The standard definition of influenza includes a fever.
    • Odd feature of new virus is the lack of fever in significant number documented cases,
    • Even in some patients become seriously ill.
    • In Chile, it was about half, in Mexico City about a third and elsewhere, less,
    • Lack of fever has been noted by other observers in several Canadian cases.

    Analysis of data from specimens yet to be tested may shed light on how often infected individuals who have no fever spread the virus.

    • Epidemiologists stress need for rigorous methodology to produce the solid data -- crucial for planning.
    • A need exists to account for the several-week delay between onset of symptoms and death in influenza and other illnesses.
    • Failure to take that time lag into account can seriously underestimate the death rate, depending on when in the pandemic the information is obtained.

    Atypical symptoms unhelpful in some patients...

    • So absence of fever among many patients, (when fever is specified in the definition), can cause serious underestimation of case totals.
    • Also, absence of fever limits the usefulness of thermal scans to identify people who have the virus and thus control the pandemic.
    • Diarrhea appears to be occurring in a larger percentage of cases than seasonal influenza, reinforcing the importance of frequent hand washing.
    • As yet, unclear when infected people stop shedding H1N1 virus, thus when to help stop spreading the illness.
    • This info particularly needed for those with impaired immune systems from H.I.V. infection, chemotherapy and anti-rejection drugs used in organ transplants.

    Mexican doctors found A/H1N1 influenza virus on the hands of workers, on tables next to patients’ beds, on other hard surfaces and on a computer mouse, Dr. Wenzel says “infection control in hospitals must be assiduous to prevent spread, particularly those with impaired immune systems.”

    • The course of illness can become life-threatening in just a few hours among patients who had shown only mild symptoms,
    • Dr. Wenzel said, “doctors know little about what treatment works in severe cases.”
    • 2 unusual features of the new virus are that pregnancy, particularly in third trimester,
    • obesity seem to increase the risk for complications of the infection.

    Dr. Anthony E. Fiore, an influenza epidemiologist at the Centers for Disease Control and Prevention in Atlanta, said that studies are under way, to clarify whether obesity is an independent risk factor for complications of influenza or whether obese people have conditions like heart disease, asthma and other chronic lung ailments that put them at such risk.

    Diagnostic Testing Problems...

    • Doctors actively involved in patient care are hampered by the lack of a standard, reliable rapid test to determine if a patient has swine influenza or some other respiratory illness.
    • The diagnosis of swine influenza A(H1N1) has to be made through special tests known as P.C.R., for polymerase chain reaction.
    • The tests are used in research laboratories but otherwise are generally available only through local and state health departments.
    • The P.C.R. tests, even if offered by a commercial laboratory, generally cannot be done in time to help a doctor determine whether a patient in an office, a clinic or a hospital has seasonal or swine influenza — a factor in determining what treatment to offer.
    • Most local and state health departments under severe budget restraints.

    “We are stuck diagnostically, while we have increased expectations of what public health departments can do, and the science behind it, we do not have the infrastructure to do it.”

    Information still incomplete...

    Dr. Schaffner said, "Health professionals and the public should be receiving more information in a timelier way about what has been learned about the swine influenza pandemic."

    Speaking about some of the gaps in clinical and epidemiological details, Dr. Schaffner said that “it is worth being tough and saying how come we do not know more.”
