Two hundred people including 12 children have been diagnosed with HIV after being treated by an unlicenced doctor in Cambodia.

Medic Yem Chrin, who made house calls for nearly two decades in the remote rice farming village of Roka, has been arrested after police say he admitted to reusing needles and syringes.

Among the infected are 16 members of the same extended family, along with the 82-year-old abbot of a nearby Buddhist monastery.Medic Yem Chrin
