Even after exposure, HIV infection can be prevented.

Even after exposure, HIV infection can be prevented.

If you’re exposed to HIV, you may be able to prevent contracting the virus yourself by taking a cocktail of¬†antiretroviral medications (ART)¬†for 28 days. The treatment isn’t 100% effective, but it can be close if it’s started within 72 hours of exposure. You can get this treatment from your doctor, at the emergency room, and from HIV and urgent-care clinics.
