Key Flu Indicators

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 September 13-19, 2009, a review of the key indicators found that influenza activity continued to increase in the United States compared to the prior weeks. Below is a summary of the most recent key indicators:

  • Visits to doctors for influenza-like illness (ILI) are increasing nationally. Visits to doctors for influenza-like illness are higher than what is expected during this time of year and have increased for six consecutive weeks now. This is very unusual for this time of year.
  • Total influenza hospitalization rates for adults and children are similar to or lower than seasonal influenza hospitalization rates depending on age group, but are higher than expected for this time of year.
  • The proportion of deaths attributed to pneumonia and influenza (P&I) based on the 122 Cities Report was low and within the bounds of what is expected at this time of year. However, 49 pediatric deaths related to 2009 H1N1 flu have been reported to CDC since April 2009, including three deaths reported this week.
  • Twenty-six states are reporting widespread influenza activity at this time. They are: Alabama, Alaska, Arizona, Arkansas, California, Colorado, Delaware, Florida, Georgia, Illinois, Kansas, Kentucky, Louisiana, Maryland, Minnesota, Mississippi, Nevada, New Mexico, North Carolina, Oklahoma, Pennsylvania, South Carolina, Texas, Tennessee, Virginia, and Washington. Any reports of widespread influenza activity in September are very unusual.
  • Almost all of the influenza viruses identified so far are 2009 H1N1 influenza A viruses. These viruses remain similar to the viruses chosen for the 2009 H1N1 vaccine, and remain susceptible to the antiviral drugs oseltamivir and zanamivir with rare exception.

*Reports can be based on syndromic, admission or discharge data, or a combination of data elements that could include laboratory-confirmed and influenza-like illness hospitalizations.

**Laboratory confirmation includes any positive influenza test (rapid influenza tests, RT-PCR, DFA, IFA, or culture), whether or not typing was done.

This table is based on data from a new influenza and pneumonia hospitalizations and deaths web-based reporting system that will be used to monitor trends in activity. This is the third week of data from this new system. The table shows aggregate reports of all influenza and pneumonia-associated hospitalizations and deaths (including 2009 H1N1 and seasonal flu) since August 30, 2009 received by CDC from U.S. states and territories. This table will be updated weekly each Friday at 11 a.m. For the 2009-2010 influenza season, states are reporting based on new case definitions for hospitalizations and deaths effective August 30, 2009.

CDC will continue to use its traditional surveillance systems to track the progress of the 2009-2010 influenza season. For more information about influenza surveillance, including reporting of influenza-associated hospitalizations and deaths, see Questions and Answers: Monitoring Influenza Activity, Including 2009 H1N1.

The number of 2009 H1N1 hospitalizations and deaths reported to CDC from April – August 2009 is available on the Past Situation Updates page.

International Situation Update

This report provides an update to the international situation as of September 25, 2009. As of September 20, 2009, the World Health Organization (WHO) regions have reported at least 318,925 laboratory-confirmed cases of 2009 H1N1 with more than 3,917 deaths, which is an increase of at least 22,454 cases and more than 431 deaths since September 13th. The laboratory-confirmed cases represent a substantial underestimation of total cases in the world, as many countries focus surveillance and laboratory testing only on people with severe illness. The 2009 H1N1 influenza virus continues to be the dominant influenza virus in circulation in the world. From April 19 to September 12, 2009, 60.6% of influenza specimens reported to WHO were 2009 H1N1 viruses. In temperate regions of the Southern Hemisphere, disease due to 2009 H1N1 is largely declining. In tropical regions, there is still substantial disease due to 2009 H1N1. In temperate regions of the Northern Hemisphere, there is increased influenza like illness (ILI) activity due to 2009 H1N1, including in most of the United States, parts of Mexico and some countries in Europe.

Updated Guidance for Child Care and Early Childhood Programs

CDC has released 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.

Key Flu Indicators

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 August 23-29, 2009, a review of these key indicators found that influenza activity increased in the United States. Below is a summary of the most recent key indicators:

  • Visits to doctors for influenza-like illness (ILI) were highest in February during the 2008-09 flu season, but rose again in April 2009 after the new 2009 H1N1 virus emerged. Current visits to doctors for influenza-like illness are down from April, but are higher than what is expected in the summer and have increased over the last two weeks.
  • Total influenza hospitalizationrates for adults and children are similar to or lower than seasonal influenza hospitalization rates depending on age group, but are higher than expected during this time of year.
  • The proportion of deaths attributed to pneumonia and influenza (P&I) was low and within the bounds of what is expected in the summer.
  • Most state health officials are reporting regional or sporadic influenza activity. Six states (Alabama, Alaska, Florida, Georgia, Mississippi, and South Carolina) and Puerto Rico are reporting widespread influenza activity at this time. Any reports of widespread influenza activity in August are very unusual.
  • Almost all of the influenza viruses identified were the new 2009 H1N1 influenza A viruses. These 2009 H1N1 viruses remain similar to the viruses chosen for the 2009 H1N1 vaccine and remain susceptible to antiviral drugs (oseltamivir and zanamivir) with rare exception.

International Situation Update

This situation report provides an update to the international situation as of August 28, 2009. As of August 23, the World Health Organization (WHO) regions have reported over 209,438 laboratory-confirmed cases of 2009 H1N1 influenza virus with at least 2,185 deaths. The laboratory-confirmed cases represent a substantial underestimation of total cases in the world as many countries focus surveillance and laboratory testing only in persons with severe illness. The 2009 H1N1 influenza virus continues to be the dominant influenza virus in circulation in the world. Decreases in disease due to 2009 H1N1 continue to be reported from South America and parts of Australia. The United Kingdom is also reporting national decreases in disease due to 2009 H1N1. In contrast, disease associated with 2009 H1N1 influenza is continuing to increase in southern Africa, and more African countries have reported their first cases. In addition, 2009 H1N1 continues to circulate in tropical countries.
