Once touted as an HIV success story, Thailand is now faced with infection rates in its gay population comparable to those in Africa’s AIDS hot spots. Over the past decade, HIV has spread rapidly among gay men, transgender people and male sex workers in Bangkok to reach epidemic levels, fuelled partly by greater use of illicit party drugs that make people less cautious about sex, experts said.
