Following China's first poultry outbreak of H5N1 since May, officials in Guangdong province announced that more than 100,000 ducks will be culled in the next few days, following the culling of more than 36,000 ducks surrounding five farms in the Panyu district of Guangdong.
Officals also tried to allay fears that this H5N1 outbreak was the result of a resistant strain, given that the ducks in the area had been vaccinated for the virus.
Guangdong Animal Epidemic Prevention Center Director Yu Yedong said the outbreak occured, "because there wasn't enough time for the vaccinations to produce sufficient antibodies before the ducks caught the virus, and most of the birds were baby ducks." He also noted that it typically takes up to 21 days for the vaccine to take hold.
As a precautionary measure, all public hospitals in the area have been placed on alert to report any abnormalities in patients that could be related to the outbreak.
