Health officials in Laos say a woman who fell ill near the Lao capital last month with symptoms of bird flu has died.
Laboratory tests had shown the 42-year-old woman had the H5 flu virus. Hours before the woman's death in a Vientiane hospital Sunday, authorities said it would take several more days to determine whether she carried the dangerous H5N1 strain.
The woman lived near a village where bird flu has infected poultry.
Last month, health officials confirmed the country's first known human case of the disease in a 15-year-old girl who also lived near Vientiane.
Bird flu first appeared in Laos in 2004. It is known to have killed 167 people worldwide since 2003, mostly in Asia.
