FDA approves Truvada, the first pill to help prevent HIV

[Guest guest]

WASHINGTON – The Food and Drug Administration on Monday approved the first drug shown to reduce the risk of HIV infection, a milestone in the 30-year battle against the virus that causes AIDS.

The agency approved Gilead Sciences' pill Truvada as a preventive measure for people who are at high risk of acquiring HIV through sexual activity, such as those who have HIV-infected partners.

Public health advocates say the approval could help slow the spread of HIV, which has held steady at about 50,000 new infections per year for the past 15 years.
