The Department of Agriculture and Rural Development of the Mekong Delta City of Can Tho reported on March 13 that a new subtype of H5N1 avian influenza virus, 2.3.2.1C, has been discovered in some outbreaks in the locality.


Anti-bird flu efforts, therefore, are being challenged because vaccination is not effective for the new subtype, Nguyen Khai Dang, Deputy Director of the Department told a meeting with the Ho Chi Minh City Pasteur Institute.

Previously, only H5N1 virus subtype 1.1 was found in the city’s affected fowls.

The department warned that bird flu could spread far and wide amidst the harvest season, the time when breeders often let their ducks seek food on rice fields.

The department confirmed that the H7N9, H10N8 and H6N1 strands have yet been found in the locality.

It continues vaccinating poultry against H5N1 while selecting suitable vaccines to beat the new bird flu subtype and keeping an eye on the development of new poultry, especially in the areas once hit by the virus and vulnerable ones.

According to the Can Tho Veterinary Department, bird flu caused 14 outbreaks in seven communes with nearly 10,400 infected fowls.

Apparently this strain is spreading south:

In 2014, the H5N1 flu virus was detected 1.1 branch outbreak in chickens in Bac Lieu, Kien Giang and Ca Mau, and the most current outbreaks in poultry (chickens, ducks, geese) in the province have H5N1 viral epidemic 2.3.2.1C branch. According to the Department of Animal Health, late 2013 and early 2014, the branch has 2.3.2.1C virus from entering the southern provinces and disease instead of common circulation 1.1 branch in the southern provinces of the previous year this. The cause may be due to the movement of poultry from north to south, then spread through the herd duck in the branch leading to the emergence 2.3.2.1C and widely circulated in the Delta Long.
