You might already know that using condoms correctly and consistently for anal and vaginal sex is effective at preventing HIV transmission. However, there are several biomedical prevention methods as well.
Undetectable = Untransmittable / U=U
If someone is living with HIV and has achieved and maintained an undetectable viral load by taking antiretroviral therapy as directed and working with their health provider, they cannot transmit the virus to their sexual partners, even without using condoms.
PrEP (pre-exposure prophylaxis)
PrEP is an effective HIV prevention method that involves taking a pill containing antiretroviral drugs every day to reduce the risk of acquiring HIV. While taking PrEP daily is the most common method, it can also be used on demand for protection with short-term partners. There is also an injectable form of PrEP that is taken every two months. While PrEP reduces the risk of HIV transmission, it does not provide protection against other STIs. Talk to a health provider to learn more about PrEP.
PEP (Post-Exposure Prophylaxis)
HIV PEP is a short treatment using HIV medicines that people can take soon after a possible HIV exposure. People must start PEP within 72 hours (3 days) after the exposure to prevent HIV infection. PEP should only be used in emergencies. If someone thinks they have been exposed to HIV, they should contact their healthcare provider right away or go to an emergency room.
