Drugs and AIDS in Southeast-Asia.
Opium dependence was indigenous to countries in the Golden Triangle area in south-east Asia (SA). Heroin epidemics developed in most SA countries in the 1960s and early 1970s and remained a significant problem particularly in Myanmar, Thailand and Malaysia until now. In contrast, the island countries in SA seemed quite free from opiate abuse. Intravenous injection (IV) of drugs appeared after the heroin epidemic and currently prevails in countries with a significant opiate abuse problem. IV of opium was particularly common in the highly urbanized cities in Vietnam. Most SA countries started HIV seroscreening in IV drug users (IVDU) around the middle of the 1980s. Rapid epidemic spread of HIV infection was observed in 1988-89 in Thailand and Myanmar. The Highest prevalence of more than 80% was reported from a study of IVDUs in Yangon, Myanmar, followed by Thailand at about 40%. Although HIV infected IVDUs were identified at the same time in Malaysia and later in Singapore and the Philippines, there was no evidence of such a rapid and severe epidemic.
