Most new infections come from unprotected sex with someone who doesn’t know they have HIV – so aren’t on medication and aren’t undetectable.
Choose your way to protect yourself and prevent HIV, from options including condoms and PrEP.
Using condoms correctly and consistently can help protect against HIV, other sexually transmitted infections (STIs) and unplanned pregnancies.
Your choice of condom makes a huge difference to how good they feel and how well they work.
Pre-exposure prophylaxis (PrEP) is a medication that someone without HIV can take. It will stop them getting HIV during sex without a condom.
It is highly effective at preventing HIV, but it does not protect against sexually transmitted infections (STIs) or unplanned pregnancy.
Post-exposure prophylaxis (PEP) is a treatment that can stop an HIV infection after the virus has entered a person’s body. It must be taken within 72 hours of exposure.
