Swine flu: the world in 11 weeks

From late April 2009 onward, World Health Organization (WHO) has been updating regularly the global Swine Flu situation on a country level. This series of Map Library maps shows the dissemination of the virus on a week-by-week basis after re-organizing data from the WHO and other sources, obtained through the update files of Centre for Health Protection, Hong Kong Special Administrative Region Government. Week One refers to the one week period beginning 20 April 2009 whereas Week Eleven refers to the week beginning 29 June. WHO stopped the regular updating after 6 July. Two sets of figures are shown – cumulative numbers (total number of confirmed cases reported) and incidence (new cases per week). Rapid transmission of the Swine Flu virus continued to be shown even by the end of this observation period. Apparently, the epidemic does not seem to have slowed down!
