Second bird flu outbreak in May hits Vietnam ducks

HANOI (Reuters) - Bird flu has infected three duck farms in central Vietnam, the second infection detected in the region in less than a month, the government said on Sunday.

Tests found the H5 component of the H5N1 virus among the samples taken after a total of 1,298 ducks died in the farms in Nghe An province on May 9, the Agriculture Ministry’s Animal Health Department said in a report.

The fowl had not been vaccinated against bird flu, it said.

Animal health workers have slaughtered the remaining 2,500 ducks in the farms, disinfected the area and banned poultry transport from the infected area.

Waterfowl are a reservoir for the disease and can spread the H5N1 virus in their droppings as they roam through rice fields. Ducks often show no symptoms of sickness, making it harder to contain the virus.

The Animal Health Department said nearly half of Vietnam’s 64 provinces have completed the first of a two-phase vaccination campaign which targets up to 90 percent of the country’s poultry stock this year.

As of Sunday, Vietnam had vaccinated 111 million poultry, including 70.3 million chickens. The remainder were waterfowl, the department said.
