Cambodia on January 25 reported three new human cases of avian influenza, two of them fatal, in the first three weeks of 2013. 

The World Health Organization and Cambodia's health ministry announced that a 15-year-old girl in a village in southeastern Takeo province and a 35-year-old man in central Kampong Speu province died after being hospitalized with avian flu, according to the Associated Press. An 8-month-old boy in the capital, Phnom Penh, was treated and survived.

Cambodia reported three cases last year, all of them fatal. Since 2005, it has recorded 21 cases, 19 of them fatal.
The disease remains hard for people to catch, but experts fear it could mutate into a more deadly form that spreads easily from person to person. So far, most human cases have been linked to contact with infected poultry.
