Chances of Getting HIV

What are your odds of getting HIV? Your odds of contracting HIV depend on a number of factors.


  • Condoms are very effective at helping to prevent the spread of HIV.
  • The risk of your partner being infected affects your risk of contracting HIV.
  • Some sexual activities are more risky than others. Vaginal and anal sex are higher-risk activities. Receptive anal sex is the highest-risk activity.
  • Anti-retroviral therapy can reduce your partner’s risk of transmitting HIV. This is known as treatment as prevention.
  • When someone acquires HIV can also influence their chances of passing on the infection.
