Mao Samnag, 28, a former prostitute who is HIV positive, sleeps in a hammock outside her shelter in a shantytown in Phnom Penh. Mao went to a Cambodian hospital for the first time just a few days ago. About 1.9 percent of the population of 13.8 million are infected with the HIV virus, and relatively few have access to treatment. Nearly 10,000 Cambodians die of AIDS-related illnesses every year, according to the government.
