The federally run Centers for Disease Control in Atlanta is recommending that people who could be exposed to HIV through unsafe sex, IV drug use, rape or accidents get a preventative regimen of drugs. This is not new in Australia, Brazil and Europe.
San Francisco health official Dr. Josh Bamberger says "We have probably the most conservative administration in the last 50 years, and yet the CDC is coming out with a policy that is more progressive than perhaps any country's in the world."
Before the CDC only recommended this for health care workers exposed on the job and that policy was devised in 1996. The CDC previously said it didn't have enough data on the effectiveness of the drugs to create a broader policy.
