The H5N1 bird flu has infected the father of an 11-year-old Cambodian girl who recently died of the virus, World Health Organization officials said Friday, as they awaited test results from 11 additional contacts of the girl.
The WHO "urges heightened vigilance from all countries," Dr. Sylvie Briand, director of Global Infectious Hazard Preparedness and Emergency Preparedness for the organization, said at a news conference. WHO officials were conferencing with Cambodian health officials, performing a risk assessment as she spoke.
