A survey to determine the prevalence of HIV/AIDS in Cambodia is due to be launched later this year. The National Centre for HIV/AIDS, Dermatology and STDs will carry out blood tests nationwide. Mean Chhivun, president of the centre, said the study will help determine the strategies needed to control the spread of HIV/AIDS. The project will cost around US$100,000. In the first six months of 2009, more than 30,000 people received antiretroviral drugs in Cambodia. In total, 67,100 Cambodians are believed to be infected.
