Three Cambodian sex workers wait for customers at a brothel in Phnom Penh July 11. Cambodia has the highest HIV infection rate in Asia with an estimated 200,000 people out of a population of 11.5 million carrying the virus that causes AIDS. AIDS in Cambodia is spread largely through unprotected heterosexual sex. Health officials say the virus is spreading from high-risk groups, in particular sex workers and their cliients, into the broader community.
