The department said that ducks died in Phuong Thach commune, Cang Long district, Tra Vinh province, from June 24.
By July 4, around 1,000 unvaccinated ducks had died. Their samples were tested positive to H5N1 virus.
The above comments describe the continued presence of H5N1 in southern Vietnam. Although Vietnam has been culling and vaccinating poultry for several years, H5N1 remains endemic in the area and is continuously reported in unvaccinated birds.
However, recent reports from Hong Kong and Egypt raise concerns that the current vaccination approaches have limited utility, and the continuing reports of H5N1 in Vietnam may reflect these shortcomings.
