:: Human infection with avian influenza A(H7N9) virus – update 14 February 2014
The National Health and Family Planning Commission (NHFPC) of China and the Centre for Health Protection (CHP), Hong Kong, SAR, China has notified WHO of a total of eight additional laboratory-confirmed cases of human infection with avian influenza A(H7N9) virus, including one death…So far, there is no evidence of sustained human-to-human transmission….

While the recent report of avian influenza A(H7N9) virus detection in live poultry exported from mainland China to Hong Kong SAR shows the potential for the virus to spread through movement of live poultry, at this time there is no indication that international spread of avian influenza A(H7N9) has occurred. However as the virus infection does not cause signs of disease in poultry, continued surveillance is needed.

Should human cases from affected areas travel internationally, their infection may be detected in another country during or after arrival. If this were to occur, community level spread is unlikely as the virus does not have the ability to transmit easily among human. Until the virus adapts itself for efficient human-to-human transmission, the risk of ongoing international spread of H7N9 virus by travellers is low. The overall risk assessment has not changed.

Further sporadic human cases of avian influenza A(H7N9) infection are expected in affected and possibly neighbouring areas, especially given expected increases in the trade and transport of poultry associated with the Lunar New Year…
