HANOI, Vietnam (AP) — Health officials say a Vietnamese boy has died of the H5N1 virus. It is the country’s third human bird-flu death this year.

Nguyen Huy Nga of Vietnam’s Ministry of Health said the 3-year-old boy died Thursday at a hospital in Ho Chi Minh City.

Provincial health director Hoang Van Phi said the boy became ill on March 10 after eating a duck that his family had slaughtered at their home in Dong Thap province in southern Vietnam.

Dong Thap is some 119 miles (190 kilometers) west of Ho Chi Minh City.
