3 more human H7N9 cases in China

China reported three more human H7N9 virus infections on Wednesday.

Three men aged 84, 58 and 46 in east China's Zhejiang Province were confirmed on Tuesday to have contracted the virus, bringing the total to 82 for the province.

The oldest patient is in a critical condition and the other two cases, severe.

China has reported more than 120 human H7N9 cases this year, including at least 31 deaths.

Medical experts are yet to find any evidence of widespread human to human transmission, but warn that poultry raised in people's homes is a source of danger if exposed to birds from poultry markets.
