receptive
| Prevention measure | Reduction in risk |
|---|---|

| Condom use during vaginal sex | 71% |
| Condom use during anal sex | 70% |

What is the most common route of HIV transmission?
Most people who get HIV get it through anal or vaginal sex, or sharing needles, syringes, or other drug injection equipment (for example, cookers). But there are powerful tools that can help prevent HIV transmission.
What are the odds of catching HIV from an infected person?
Therefore, unprotected sex with an HIV-positive person who has acute HIV infection could carry a transmission risk of up to 2% (the equivalent of 1 transmission per 50 exposures) for receptive vaginal sex and over 20% (equivalent to 1 transmission per 5 exposures) for receptive anal sex.
How does HIV transfer from female to male?
When a woman has vaginal sex with a partner who’s HIV-positive, HIV can enter her body through the mucous membranes that line the vagina and cervix. Most women who get HIV get it from vaginal sex. Men can also get HIV from having vaginal sex with a woman who’s HIV-positive.
What’s the probability of HIV transmission?
Transmission can occur after one exposure. A risk of 1% would mean that an average of one infection would occur if 100 HIV-negative people were exposed to HIV through a certain type of sex. It does not mean that a person needs to be exposed 100 times for HIV infection to occur.
What are my chances of contracting HIV?
A report by the Black AIDS Institute states that African-American same-gender-loving men have a 25 percent chance (which is one in four odds) of contracting HIV by the time they’re 25 years old—and a 60 percent chance by the time they’re 40.
What is the highest risk of HIV transmission?
There is a high risk of transmitting HIV through blood. According to the , direct blood transfusion is the route of exposure that poses the highest risk of transmission. While uncommon, receiving a blood transfusion from a donor with HIV may increase the risk.
