Using numbers of cases reported from the WHO and the CDC website, I made a graph of the development of the total number of cases over time and the number of countries involved. The numbers are based on the laboratory confirmed cases published by the WHO, only the first numbers came from the CDC web site.
Countries are no longer required to test and report individual cases that are laboratory confirmed, thus there are no reliable numbers available after July 6th.
Development of laboratory confirmed cases of H1N1
Since July 6th countries are no longer required to test and report individual cases, so the real number of cases is probably higher than the number of cases reported.
Average daily rate of new cases
Google Flu Trends
Google takes a different approach to estimating the development of the flu globally. They use that the number of people in a region searching for flu related topics correlates with the number of cases in that region. Quite an interesting approach to epidemiology for diseases that do not have to be registered. Visit Google Flu Trends.
