Together, these tests are highly sensitive, meaning that they rarely produce false negatives, and are accurate when performed as soon as 10 days after the individual has been infected with...

With the virus embedded in the local duck and chicken population, repeated human-bird contact means "it's inevitable you'll get human infection," says Webster. Vietnam is trying to halt such infections by modernizing its poultry industry, limiting human-bird contact, but that won't be easy.
