PrEP approved in the USA

PrEP is a course of drugs designed for people who are not HIV-positive but are at high risk of being exposed to the virus – for example, if they have an HIV-positive partner or regularly inject drugs. By 2012, the evidence is clear that, when taken daily, PrEP reduces the chance of acquiring HIV by more than 90%. The US is the first country to approve its use as a method of HIV prevention. PrEP offers an extra option for protection that could be combined with condoms and other prevention methods.
