As of 10 March 2017, 21 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 suspected infection locations of these cases (yellow dots) in China. In retrospect, the first human case of H7N9 was reported in China in March 2013. Globally over 1300 cases have been reported. The geographic distribution of all cumulative cases by province (as of 10 March 2017) is shown in graduated colour. 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 avian influenza outbreaks in Guangdong Province. Data for the map were obtained from multiple media sources derived from reports in different health authorities.

截至2017年3月10日,香港報告了21例人類感染H7N9禽流感個案,全部曾經到過內地及部份可能接觸過家禽,屬非本地感染。地圖顯示香港病者在中國城鎮的懷疑感染位置(黃點)。回顧H7N9歷史,中國在2013年3月發現首宗人類感染病例,現時全球累積總數一千三百多人。省份顏色顯示截至2017年3月10日累積個案的地理分佈。香港鄰近廣東,發生的H7N9病例在時間地點上也和廣東疫情吻合,這點也是最令人擔憂。相信香港未來情況將會取決於廣東省的禽流感疫情的控制。地圖數據源自不同的媒體根據衛生部門發放資料所作的報導。
