I'm maintaining a thread on published recent H1N1 swine virus hospitalizations: deaths by state and was surprised to see this today.... wonder why? One would think its more important and interesting than ever.....
The Influenza Division is in the process of updating their existing surveillance systems in response to the outbreak caused by influenza H1N1 swine virus to provide more timely data. The weekly surveillance report (FluView) for week 16 (week ending April 25, 2009) will not be posted Friday, May 1, 2009. The most current information on the influenza H1N1 swine virus investigation is available at http://www.cdc.gov/h1n1flu/.
It is important to remember the following about influenza surveillance in the United States:

It is important to remember the following about influenza surveillance in the United States:
- All influenza activity reporting by states and health-care providers is voluntary.
- The reported information answers the questions of where, when, and what influenza viruses are circulating. It can be used to determine if influenza activity is increasing or decreasing, but cannot be used to ascertain how many people have become ill with influenza during the influenza season.
- The system consists of nine complementary surveillance components in five categories. These components include reports from more than 150 laboratories, 2,400 outpatient care sites, vital statistics offices in 122 cities, research and health-care personnel at the NVSN and EIP sites, and influenza surveillance coordinators and state epidemiologists from all 50 state health departments, and the District of Columbia health department.
- Influenza surveillance data collection is based on a reporting week that starts on Sunday and ends on Saturday of each week. Each surveillance participant is requested to summarize weekly data and submit it to CDC by Tuesday afternoon of the following week. Those data are then downloaded, compiled, and analyzed at CDC. The report is distributed and posted on this Web site each Friday from October through mid-May.
