The data on this is taken from a Google
My Map of the H1N1 Swine Flu Outbreak. The data cannot be taken as being accurate. For example, the timestamps of the data is reporting cases in the USA before cases in Mexico so the timeline seems to suggest the outbreak spread from the US to Mexico rather than the other way around.
The default view means that you have to zoom out to see cases reported in Europe
and the rest of the world. This map was created by Google
