More than 520 close contacts of the confirmed cases are being closely monitored. In Jiangsu, investigation is ongoing into a contact of an earlier confirmed case who developed symptoms of illness.
In addition, Shanghai government officials closed down the Huhuai market and more than 20,000 birds were culled after authorities detected H7N9 avian influenza in pigeon samples.
The Chinese government is actively investigating this event and has heightened disease surveillance. The animal health sector has intensified investigations into the possible sources and reservoirs of the virus. To date, officials have no evidence of person-to-person transmission of H7N9 avian influenza.
