PHNOM PENH, Cambodia (AP) — Cambodia says a 7-year-old girl is its sixth death from bird flu this year.

The Health Ministry said Friday the girl from Prey Veng province died June 7 of respiratory complications. Cambodia has now had 16 cases, and 14 victims have died. Its previous annual high was four deaths in 2005.

The ministry and the World Health Organization say 555 cases of bird flu have been confirmed since 2003 globally and 324 were fatal.

The H5N1 virus first raged across Asia in 2003, devastating poultry stocks. Many countries have improved farm hygiene to attack the virus at its source. Most human infections have been linked to close contact with sick birds.
