June 4, Novel Influenza A (H1N1) - Congressional Update

We are providing this document to help inform Congress and congressional staff about the current status of the novel Influenza A (H1N1) events. Beginning this week, Congressional Update will be issued on Mondays and Thursdays unless events dictate otherwise. Any questions should be directed to CDC/Washington at 202-245-0600.

Note: Green text indicates new information. Black text indicates background and other information also included in previous updates.

U.S. Update

As of June 3, 2009 11:00 AM ET, a total of11,054 confirmedand probable human cases of novel Influenza A (H1N1) have been identified in the United States in all 50 states plus the District of Columbia and Puerto Rico. There have been 17 deaths from novel Influenza A (H1N1), 4 in Arizona, 4 in New York, 3 in Texas, 3 in Illinois, and 1 each in Missouri, Utah, and Washington. The number of confirmed and probably cases is thought to represent a small proportion of the total number of people who have been infected with the novel H1N1 virus, because many people ill with influenza-like symptoms do not seek medical care and many who do seek medical care are not tested for influenza.

A summary of the cases is provided below. All questions related to specific cases should be directed to the state health department in the state in which the case occurred. A full list of state health departments and their contact information is available at http://www.astho.org/Programs/Infectious-Disease/H1N1/ under State H1N1 Information. Links to novel Influenza A (H1N1) Web sites for each state are located at http://www.cdc.gov/h1n1flu/states.htm.

International Update

The World Health Organization (WHO) is providing information on international novel Influenza A (H1N1) outbreaks at: http://www.who.int/csr/disease/swineflu/en/index.html.

On April 29, 2009 WHO raised the level of influenza pandemic alert from phase 4 to phase 5. Information on WHO’s pandemic influenza phases is available at: http://www.who.int/csr/disease/avian_influenza/phase/en/index.html.

In view of the threat posed by the current outbreak of new influenza A (H1N1), the Director-General of the World Health Organization convened a High-Level Consultation for all Member States at the start of the Sixty-second World Health Assembly on May 18, 2009. The consultation provided an opportunity for Member States to share experiences, to discuss lessons learned, and to highlight the challenges that now confront the world community. More information is available at http://www.who.int/csr/resources/publications/swineflu/High_Level_Consultation_18_May_2009.pdf.

As of June 3, 2009 6:00 GMT, 9220 cases have been reported outside of the United States. A summary of the cases is provided in the table below. As of June 3, 2009 6:00 GMT, the Government of Mexico has reported 5029 laboratory confirmed cases, including 97 deaths, of novel Influenza A (H1N1).

CDC: H1N1 (Swine Flu) Resources for the Deaf and Hard of Hearing

CDC has developed resources on novel Influenza A (H1N1) for the deaf and hard of hearing at: http://www.cdc.gov/h1n1flu/deaf.htm. The resources include a sign language hand washing video and a public service announcement on novel Influenza A (H1N1).

New Novel Influenza A (H1N1) MMWR Publication
The Morbidity and Mortality Weekly Report (MMWR) published an article, "Update: Novel Influenza A (H1N1) Virus Infection --- Mexico, March--May, 2009." The article (http://www.cdc.gov/mmwr/preview/mmwrhtml/mm5821a2.htm?s_cid=mm5821a2_e) provides an update on novel Influenza A (H1N1) in Mexico and summarizes public health actions taken to date by Mexico to monitor and control the outbreak.

How does novel H1N1 flu compare to seasonal flu in terms of its severity and infection rates?
CDC is still learning about the severity of the novel H1N1 flu virus. At this time, there is not enough information to predict with certainty how severe this novel H1N1 flu outbreak will be in terms of illness and death over the full course of this flu season, how it will compare with seasonal influenza, and whether this will change if this same virus infects large numbers in the fall. With seasonal flu, we know that seasons vary in terms of timing, duration and severity. Seasonal influenza can cause mild to severe illness, and at times can lead to death. Each year, in the United States, on average 36,000 people die from flu-related complications and more than 200,000 people are hospitalized from flu-related causes. Of those hospitalized, 20,000 are children younger than 5 years old. Over 90% of deaths and about 60 percent of hospitalization occur in people older than 65.

So far, with novel H1N1 flu, the largest number of novel H1N1 flu confirmed and probable cases have occurred in people between the ages of 5 and 24-years-old. At this time, there are few cases and no deaths reported in people older than 64 years old, which is unusual when compared with seasonal flu. However, pregnancy and other previously recognized high risk medical conditions from seasonal influenza appear to be associated with increased risk of complications from this novel H1N1.

How does CDC conduct influenza surveillance?
The Epidemiology and Prevention Branch in the Influenza Division at CDC collects, compiles and analyzes information on influenza activity year round in the United States and produces a weekly report from October through mid-May. The U.S. influenza surveillance system is a collaborative effort between CDC and its many partners in state and local health departments, public health and clinical laboratories, vital statistics offices, healthcare providers, clinics and emergency departments. Information in five categories is collected from nine different data sources.

Viral Surveillance — About 80 U.S. World Health Organization (WHO) Collaborating Laboratories and 70 National Respiratory and Enteric Virus Surveillance System (NREVSS) laboratories, located throughout the United States, participate in virologic surveillance for influenza. All state public health laboratories participate as WHO collaborating laboratories along with some county public health laboratories and some large tertiary care or academic medical centers. Most NREVSS laboratories participating in influenza surveillance are hospital laboratories. In 2007, human infection with a novel influenza A virus became a nationally notifiable condition. The 2009 influenza A (H1N1) virus is a novel virus. Novel influenza A virus infections include all human infections with influenza A viruses that are different from currently circulating human influenza H1 and H3 viruses.
Outpatient Illness Surveillance — Information on patient visits to health care providers for influenza-like illness is collected through the U.S. Outpatient Influenza-like Illness Surveillance Network (ILINet).
Mortality Surveillance — Rapid tracking of influenza-associated deaths is done through two systems:
122 Cities Mortality Reporting System. Each week, the vital statistics offices of 122 cities report the total number of death certificates received and the number of those for which pneumonia or influenza was listed as the underlying or contributing cause of death by age group. The percentage of all deaths due to pneumonia and influenza (P&I) are compared with a seasonal baseline and epidemic threshold value calculated for each week.
Surveillance for Influenza-associated Pediatric Mortality. Influenza-associated deaths in children (persons less than 18 years) was added as a nationally notifiable condition in 2004. Laboratory-confirmed influenza-associated deaths in children are reported through the Nationally Notifiable Disease Surveillance System.
Hospitalization Surveillance — Two systems monitor hospitalizations with laboratory confirmed influenza infections.
Emerging Infections Program (EIP). The EIP Influenza Project conducts surveillance for laboratory-confirmed influenza related hospitalizations in children (persons less than 18 years) and adults in 60 counties covering 12 metropolitan areas of 10 states (San Francisco CA, Denver CO, New Haven CT, Atlanta GA, Baltimore MD, Minneapolis/St. Paul MN, Albuquerque NM, Las Cruces, NM, Albany NY, Rochester NY, Portland OR, and Nashville TN).
New Vaccine Surveillance Network (NVSN). The New Vaccine Surveillance Network (NVSN) provides population-based estimates of laboratory-confirmed influenza hospitalization rates for children less than 5 years old residing in three counties: Hamilton County OH, Davidson County TN, and Monroe County NY.
Summary of the Geographic Spread of Influenza — State health departments report the estimated level of spread of influenza activity in their states each week through the State and Territorial Epidemiologists Reports. States report influenza activity as no activity, sporadic, local, regional, or widespread.

Travel

As the summer travel season begins, CDC recognizes that both you and your constituents are concerned about the possible impact of flu on travel plans. At this time, CDC is not recommending exit screening of travelers, but is encouraging people who are feeling ill to defer their travel plans until they are well.

CDC is continuing to develop updated travel guidance and resources for business and recreational travelers. Please go to www.cdc.gov/travel for more information, and check back at this site, or call 1-800-CDC-INFO, for more information about healthy and safe travel.

Where to Find Updates

CDC is committed to ensuring Congress, public health partners, the media, and the public are able to obtain up-to-date and accurate information regarding the human novel Influenza A (H1N1) cases and CDC’s related activities.
