Story maps

As of the end of December 2014, 11 human cases of avian influenza H7N9 have been reported in Hong Kong. All were imported cases from China, as the patients had history of travelling to Mainland China and some had possible exposure to poultry. The map shows the locations of the 11 cases in China and Hong Kong. Around the world the first human case was reported in China almost 2 full year ago, back in March 2013. The inset map shows the geographic distribution of all cumulative cases in China (as of 31 December 2014). The spatiotemporal relationship between H7N9 cases in Hong Kong and Guangdong is a cause for concern. This also suggests that the future occurrence of H7N9 in Hong Kong would depend largely on the control of outbreaks in poultry in Guangdong province. Data for the map were obtained from multiple media sources derived from reports in different health authorities.
