Human infection with avian influenza A(H7N9) virus in China - update ----------------------------------------------------------- As of 22 April 2013 (18:00 CET), the National Health and Family Planning Commission notified WHO of an additional 2 laboratory-confirmed cases of human infection with avian influenza A(H7N9) virus. Both the patients are reported from Zhejiang province. The 1st patient is a 54-year-old woman who became ill on 16 Apr 2013 and the 2nd patient is a 32-year-old man who became ill on 14 Apr 2013. Additionally, a patient earlier reported from Zhejiang province has died.
To date, a total of 104 [now 108, see below] laboratory-confirmed cases of human infection with avian influenza A(H7N9) virus in China, including 21 [now 22, see below] deaths have been reported to WHO. Contacts of the confirmed cases are being closely monitored. National authorities continue to implement prevention and control measures.
Investigations into the possible sources of infection and reservoirs of the virus are ongoing. Until the source of infection has been identified, it is expected that there will be further cases of human infection with the virus in China. So far, there is no evidence of ongoing human-to-human transmission. WHO does not advise special screening at points of entry with regard to this event, nor does it recommend that any travel or trade restrictions be applied.
At the invitation of the National Health and Family Planning Commission of China, WHO has convened a team of experts who will visit areas affected by avian influenza A(H7N9) in China in order to provide recommendations on the prevention and control of the disease.
