Internationally, here is the situation: This report provides an update to the international situation as of September 18, 2009. As of September 13, 2009, the World Health Organization (WHO) regions have reported more than 296,471 laboratory-confirmed cases of 2009 H1N1 influenza virus (2009 H1N1) with at least 3,486 deaths, which is an increase of at least 18,864 cases and 281 deaths since September 6th. 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. Since April 2009, 60.7% of influenza specimens reported to WHO were 2009 H1N1 viruses.
http://www.cdc.gov/h1n1flu/updates/international/091809.htmThe CDC has changed the reporting structure for the H1N1 virus on August 30th and the counter was "reset" to zero for US pandemic info. This was not too long after the H1N1 strain really started taking off. Here's some quotes from the CDC: You can read the whole thing here:
http://www.cdc.gov/h1n1flu/reportingqa.htmDo the numbers reported now include 2009 H1N1 cases in the spring and summer?No. The number of reported hospitalizations and deaths was “re-set” to zero on August 30. The report of the first week of data for the newly defined system will appear in the September 11, 2009 FluView.
If states are reporting aggregate influenza hospitalizations and deaths, how will you tell what percentage of cases is due to 2009 H1N1 and what percentage is due seasonal influenza viruses?Due to CDC’s new case definitions, there will be no definitive way to differentiate between hospitalizations and deaths due to seasonal influenza versus those due to 2009 H1N1 influenza from aggregate reporting. And some deaths that are not due to influenza specifically will be included. However, information on the proportion of influenza viruses that are 2009 H1N1 versus seasonal influenza will continue to be reported in FluView from the virologic surveillance system. (For example, as of August 29, 2009, 97% of all subtyped influenza A viruses being reported to CDC were 2009 H1N1 viruses.)
Why did CDC stop reporting confirmed and probable 2009 H1N1 flu cases?Individual case counts were kept early during the 2009 H1N1 outbreak when the 2009 H1N1 virus first emerged. As the outbreak expanded and became more widespread, individual case counts become increasingly impractical and not representative of the true extent of the outbreak. This is because only a small proportion of persons with respiratory illness are actually tested and confirmed for influenza (including 2009 H1N1) so the true benefit of keeping track of these numbers is questionable. In addition, the extensive spread of 2009 H1N1 flu within the United States made it extremely resource-intensive for states to count individual cases. On July 24, 2009, CDC discontinued reporting of individual cases of 2009 H1N1, but continued to track hospitalizations and deaths.
So although there are many cases of the regular seasonal flu going around (still much earlier than usual) the H1N1 is still spreading at an alarming rate.
