China has confirmed its first human cases of bird flu, while Indonesia has announced two more human deaths from the virus.
In China's eastern province of Anhui, officials say a 24-year-old poultry worker died of bird flu. In southern Hunan province, a nine-year-old boy who caught the virus has since recovered. Health officials suspect, but cannot confirm, that the deadly H5N1 virus may have killed the boy's sister last month.
Meanwhile, Indonesia's health ministry says two young women, ages 20 and 16, died last week from bird flu. Both victims, who died in Jakarta, are said to have had contact with dead chickens. That brings the total of confirmed bird flu deaths in Indonesia to seven.
The H5N1 strain has claimed more than 60 lives in East Asia since 2003. Scientists fear the strain could mutate and be passed from human to human.
