H5N1 bird flu infection was found in Ke Sach district of Vietnam's southern Soc Trang province, with the fowls infected for less than 21 days, according to the Preventive Medicine Agency under the Ministry of Health on Thursday.

A report from the Soc Trang Veterinary Department said the reported H5N1-infected poultry were raised by a family in Dai Hai commune of the district, and more than 1,100 two-month-old fowls were culled while measures were applied to prevent the infection from further expansion, the Saigon Giai Phong Daily reported.

Doctors have advised local residents not to eat dead poultry and take hygienic measures when touching poultry and their cages so as to reduce the risks of H5N1 infection. When being infected, people should go to medical stations for timely treatment.
