Health officials in Vietnam say a deadly strain of the bird flu virus has killed a second Vietnamese man this week, raising the country's death toll from the virus to 50.
Officials say the 27-year old man from Vietnam's northern Ninh Binh province died late Thursday and tested positive for the H5N1 strain of bird flu.
Officials say the man fell ill after slaughtering two chickens at his home. He is the third person to die from avian influenza in Vietnam this year.
Not counting the latest death, the World Health Organization says 227 people around the world have died from bird flu since 2003. Most of the world's cases, 103, have occurred in Indonesia.
