FAST FACTS

U=U

Treatment with an undetectable viral load prevents sexual transmission.

INFOGRAPHIC

HIV prevention options

HIV prevention can combine tools that fit the situation and the person's needs.

  • Condoms can help prevent HIV and certain other sexually transmitted infections when used correctly.
  • PrEP is medicine used before possible exposure by people without HIV.
  • HIV treatment can lead to an undetectable viral load and prevent sexual transmission.
  • PEP is emergency medicine that must be started within 72 hours after a possible exposure.

CHANCE OF GETTING HIV PER SEX ACT

ONE ACT · DIFFERENT PROTECTIVE FACTORS

How prevention changes this example

CDC estimates per 10,000 receptive anal sex acts. The sex act stays the same; the protective factor changes.

  1. No protective factorNo condom, PrEP, or ART; the partner with HIV is not virally suppressed.
    138
  2. External condomThe insertive partner uses a condom.
    39
  3. PrEPThe HIV-negative partner uses PrEP optimally or consistently.
    about 1
  4. Treatment + undetectableThe partner with HIV gets and keeps an undetectable viral load.
    0
Why this comparison helps

It shows the effect of prevention tools without suggesting that one population estimate can predict one person’s outcome.

Options can be combined. Your circumstances, correct use, timing, and viral load matter; ask a qualified provider for individual advice.

What Compare HIV prevention options means for you

Prevention can include PrEP, PEP, condoms, lubricant, STI testing, sterile injection equipment, and HIV treatment with an undetectable viral load. That short answer is the place to begin; what matters next is how it fits your situation—your reason for reading, the timing of any event, and the support you can reach. Treat this guide as a map: it can help you prepare and ask better questions, while a qualified health professional applies the details to you.

02

The essentials for Compare HIV prevention options

Prevention combines tools: PrEP before a possible exposure, PEP as an emergency within 72 hours, condoms with compatible lubricant, sterile injection equipment, and testing. Someone on treatment with an undetectable viral load does not pass HIV on through sex (U=U). Each option has its own follow-up, and a clinician can help combine them—one method does not have to replace the others.

03

Turn it into one next step

You do not need perfect medical words. Note any relevant dates, test names, or medicines, then choose one manageable action. For this page, a useful next step is talk to a prevention service—a suggestion, not a rule. If it feels too big, make it smaller: save a phone number, check opening hours, or tell someone you trust. The plan can change as a result or new information arrives.
