WHO has published Human infection with avian influenza A(H7N9) virus – update. Excerpt:
On 23 June 2014, the National Health and Family Planning Commission (NHFPC) of China notified WHO of one additional laboratory-confirmed case of human infection with avian influenza A(H7N9) virus.
The patient is a 51-year-old male from Taizhou City, Zhejiang Province. He had onset of symptoms on 2 June, was admitted to hospital on 6 June, and is currently in a severe condition. The patient has a history of exposure to live poultry.
The Chinese Government has taken the following surveillance and control measures:
1. Strengthen surveillance and situation analysis;
2. Reinforce case management and medical treatment;
3. Conduct risk communication with the public and release information.
The overall risk assessment has not changed.
The previous 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.
