(AP)—Two more children have died in Cambodia of bird flu, bringing the number of fatal cases to four since the start of this year.
The Cambodian office of the U.N.'s World Health Organization said a 17-month-old girl from central Kampong Speu province and a 9-year-old girl from southern Kampot province died Monday after being hospitalized.
Last week, Cambodia reported three human cases of bird flu, two of them fatal. For of all 2012, the country reported a total of three cases, all fatal.
Cambodia since 2005 has reported 26 cases, 23 of them fatal.
WHO says bird flu, also known as avian influenza, or H5N1, has killed 360 other people worldwide since surfacing in 2003. Most human cases have been linked to contact with infected poultry.
