PHNOM PENH, Cambodia (AP) — An 11-year-old boy in Cambodia died from bird flu, the country’s fourth victim of four confirmed cases of the infection this year, the Health Ministry announced Wednesday. The ministry issued a statement saying laboratory tests from the Pasteur Institute of Cambodia confirmed the boy, who lived in a village in the western province of Kampong Speu, died Tuesday of H5N1 avian influenza, as the infection is formally called. An investigation found there were several chickens and ducks near the boy’s house that had been sick and dying for a week before the child started feeling ill, the ministry said.
