Three cases are reported to have had a history of exposure to live poultry. Investigations are ongoing.
Details of the cases notified on 14 February are as follows:
- A 78 year-old man from Guangzhou City, Guangdong Province, who became ill on 7 February and was admitted to hospital the same day. He died on 14 February.

The WHO describes the risks of human infection as:
Sporadic human cases
The overall risk assessment has not changed (see WHO Risk Assessment under 'Related links').
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.
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.
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.
