A man suffering from bird flu died Friday morning, the second death in two days and the third since the beginning of the year, DPA quoted a Vietnamese official as saying. The 27-year-old man had been admitted to a hospital in Ninh Binh province, 120 kilometers south of Hanoi, on Monday, and transferred to Hanoi the following day, according to Dinh Quoc Su, head of Ninh Binh's Animal Health Department. The Ministry of Health announced late Thursday that the man had tested positive for the H5N1 avian flu virus. Su said Doan and his family had eaten chicken bought at a local market during Tet, the Vietnamese lunar New Year's festival, which began on February 7. He said local authorities had disinfected Doan's neighborhood and were trying to find out exactly where he had bought the chicken. "Neither Doan's wife nor his 4-year-old son have shown any bird flu-like symptoms, but doctors are monitoring them," Su said.
