The first outbreak affected a flock of 1,500 ducks, while a second outbreak involved 3,500 chickens and ducks at a nearby household.

In response, local officials suspended the sale, transport, and slaughter of poultry products in the affected villages and conducted disinfection measures around outbreak sites to help prevent further spread of the virus.
