The 35-year-old man, who lived near a poultry market, died in October after eating a chicken with his family. They, however, are fine. In Vietnam alone, 42 people have died from the H5N1 strain of avian flu.In Indonesia, tests are being carried out on a teenager thought to have died from the disease. The 16-year-old girl lived near a bird market in the capital Jakarta, but no evidence of direct contact with infected fowl has been established. All the human cases have been seen in Asia, although the strain has killed birds in Russia and eastern Europe. In Geneva, health experts are into the second day of a three-day conference on ways of stopping the virus from mutating into a version that could pass easily from human to human. All agree it is imperative to control the spread of H5N1 in animals.
