DAILY PILL TO PREVENT HIV APPROVED IN THE U.S.A

The US food and drug administration approved Truvada, the first daily pill intended to prevent HIV transmission in people having sex with infected individuals. In a clinical trial where HIV negative individuals had unprotected sex with multiple partners including some that were HIV positive, the drug, taken daily reduced the risk of infection by 42% compared with a placebo. In another trial, with couples with one partner infected, the study found that with daily use of the drug in combination with effective condom use, the  effectiveness of the drug increased to 75%.
''The data clearly demonstrates that Truvada as a pre-exposure prophylaxis is effective at reducing the risk of HIV exposure through sexual exposure'' said Dr Connie Celum a professor of global health and medicine at the University of Washington who conducted the heterosexual studies.
