China's agriculture ministry says the highly pathogenic H5N6 strain of bird flu has been confirmed at a poultry farm in the southwestern province of Sichuan.
The ministry says that 1,840 out of about 2,500 chickens at the poultry farm died of avian flu caused by the H5N6 virus. The remaining chickens were culled to prevent the infection from spreading.
Earlier this month, the ministry said that the highly pathogenic H5N1 strain of bird flu was detected at a poultry farm in Hunan Province.
Chinese authorities are apparently stepping up measures against the series of bird flu outbreaks as they also contend with the spread of new coronavirus infections in the country.
