Southern Ninh Thuan province has culled nearly 10,000 swallows following tests that showed they had the avian influenza H5N1 virus.

The birds account for nearly 10 percent of those bred at 592 Thong Nhat Street, Phan Rang – Thap Cham city, where over 4,000 swallows have died between March 28 and early April.

Disinfectants were sprayed around the breeding facility, and samples from the remaining flock were taken for tests.

The provincial Veterinary Branch Office is closely monitoring the swallows at the facility. It also instructed other bird farms to spray disinfectants once a day during a week and enforce workers to wash their hands with soap.

Swallow breeding facilities have been requested to notify relevant agencies straight away whenever any abnormal symptom or death occur.

So far, no H7N9 case, a new strain of bird flu virus that emerged in China over the past month, have been recorded in Vietnam.-VNA
