China and Vietnam face H5N1 outbreaks
Chinese officials reported a large H5N1 outbreak at a duck farm in the southeastern province of Guangdong. A day earlier, Vietnamese veterinary officials announced an outbreak among poultry in Hoa Binh province, according to CIDRAP News.
The Chinese outbreak began at a farm in the city of Zhanjiang. The virus sickened more than 14,000 ducks out of the nearly 73,000 located at the facility. Of those that fell ill, 6,300 died. The remaining ducks were culled to prevent the disease from spreading.
Chinese health authorities have yet to determine the source of the outbreak, but have limited poultry movement in the area, and are screening birds and have sprayed and disinfected the affected area in response, CIDRAP News reports.
Vietnamese officials reported that H5N1 avian influenza struck poultry in a village in the mountainous Hoa Binh province, located in the northwestern portion of the country.
The OIE announced that all 400 of the susceptible birds in the area have died as a result of infection. The source of the outbreak remains unknown, but Vietnamese officials have implemented control measures including disinfection and placing limits on poultry transport.
