In December 2014, cases of HIV infection were detected in Roka, a village in Battambang province, northwestern Cambodia. Of more than 2,000 villagers tested for HIV, 242 people, aged from 2 to 89 years are diagnosed positive. Their common point: they were all treated by a "doctor" without a degree who reused the same syringes for several patients. Arrested in December 2014, he was sentenced at the end of 2015 to 25 years in prison.
