Cambodian health officials are looking for three US-Cambodians who were aboard a South Korean flight Sunday after one passenger who deplaned in Incheon was found carrying H1N1 flu.
Officials in Cambodia emphasized that the threat of infection was low, but were searching for the three, who they thought might be in Kampot province.
South Korea put out a warning Wednesday, saying the three had been among 93 on an Asiana Airlines flight from Seattle to Incheon, South Korea, before transiting for a Phnom Penh flight.
One woman from the first flight was quarantined in South Korea and confirmed to have the H1N1 virus, sometimes called swine flu.
