Human infection with avian influenza A(H7N9) virus – update
On 22 January 2014, the National Health and Family Planning Commission of China notified WHO of 10 additional laboratory-confirmed cases of human infection with avian influenza A(H7N9) virus.
A surge in cases of the deadly new strain of bird flu has been reported in China at the beginning of 2014. Only a handful of people had been infected with H7N9 since June, but health officials have reported 73 cases so far this month. Influenza researchers argue the winter season and preparations for Chinese New Year may be driving the increase. The World Health Organization called for vigilance, saying the virus was likely to remain present for some time.
