'Tenofovir' reduces HIV infection among injection drug users: study

BANGKOK, June 13 (Xinhua) -- Regular intake of AIDS drug " Tenofovir" can help reduce the risk of HIV infection among injection drug users, according to a research conducted by Thai and U.S. scientists.

The researchers said a daily dose of 'Tenofovir', scientifically known as Pre-Exposure Prophylaxis (PrEP), can help prevent HIV infection by 49 percent among injection drug users, while a regular dose of the drug can help reduce the risk by 74 percent.

The study, started in 2005 in Bangkok, was conducted by scientists from the Thai government and the U.S. Centre for Disease Control and Prevention (CDC) among 2,413 participants aged 20 and 60 years who were HIV-negative at baseline, and had injected drugs during the prior year.

The results were published online by the medical journal The Lancet. The authors noted that of the 2.5 million people worldwide who contracted HIV in 2011, 1 in 10 cases was likely caused by injecting drug use. Some countries in Eastern Europe and central Asia report that more than 80 percent of all HIV infections are caused by drug use.

The Bangkok Metropolitan Administration (BMA), Thailand's Public Health Ministry and the CDC will apply the study's results to further prevent HIV infection in Thailand.
