Additionally, two patients earlier reported have died.
To date, a total of 128 laboratory-confirmed cases of human infection with avian influenza A(H7N9) virus including 26 deaths have been reported to WHO. Contacts of the confirmed cases are being closely monitored.
The authorities in the affected locations 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 and controlled, it is expected that there will be further cases of human infection with the virus.
