How many cases of Swine Flu have there been in the 2009 pandemic?

Answer 1

From the World Health Organization (WHO):

"5 March 2010 -- As of 28 February 2010, worldwide more than 213 countries and overseas territories or communities have reported laboratory confirmed cases of pandemic influenza H1N1 2009, including at least 16455 deaths.

Summary: In the temperate zone of the northern hemisphere, transmission of virus persists in some areas of Europe and Asia but influenza activity is declining and at low level in the most areas. The most active areas of transmission are currently observed in parts of Southeast Asia and East and South-eastern Europe. Recently, influenza type B is increasingly reported in Asia."

From the Centers for Disease Control and Prevention (CDC):

"2/12/10 Estimated number of cases and deaths in the US:

Cases: 57 million Deaths: 11,690

The cumulative total of cases of influenza world wide that are attributed to the H1N1/09 Pandemic Swine Flu are 1562049 cases.

There have been 16665 deaths.

~ As of 1/05/10

Answer 2

There is no longer good data on the counts. There may be some ongoing cases in limited locations around the world. However, the specifics and counts of cases are no longer being tracked by CDC, WHO, the US states, and most other countries, now that the pandemic has been declared over. Influenza cases are monitored, but specific H1N1/09 counts (and the lab tests needed to isolate the specific virus to be able to count them correctly) aren't being done. Influenza cases in general are monitored, but statistics are not being kept for H1N1/09 cases separately from other influenza types for reporting any longer in the post pandemic phase.

Answer 3

Estimates of the total numbers who have contracted the A-H1N1/09 Virus are impossible to make since so many cases go unreported and/or untested to confirm the specific virus is involved, especially in the areas of the Southern Hemisphere where the regular flu season is also ongoing with cases also being caused by influenza strains different than A-H1N1/09 (Swine Flu). The numbers are very large, but luckily the severity of the disease is milder than other strains often are.

There is a count available world wide of laboratory confirmed cases and the deaths related to those which as of 8/25/09 is 271,832 cases, and 2798 deaths.
