Changes in reporting requirements for pandemic (H1N1) 2009 virus infection

16 JULY 2009 | GENEVA — As the 2009 pandemic evolves, the data needed for risk assessment, both within affected countries and at the global level, are also changing.

Data are those published by WHO. You may want to add their RSS to your reader. I’ll keep updating the graph as long as the alert level will not drop below 4. Feel free to copy it and use it; just avoid to link it with antivax insanity please.

16.05.09 added an insert to follow the variation of new cases reported at each update: C_Un-C_Un-1

19.06.09 Simplified graph
