What is the likelihood of getting HIV from sexual intercourse?

What is the likelihood of contracting HIV, the virus that causes AIDS, from sexual intercourse? The following table shows the rough estimates:

Vaginal sex, female to male, without condom.04%
Vaginal sex, male to female, without condom.08%
Receptive anal sex, without condom1.38%
 
Insertive anal sex, without condom.11%
Receptive fellatio.04%

Please note that the above values are estimates and should be interpreted with caution as some encounters may have significantly higher rates of HIV infection (e.g. cases involving bleeding after insertive anal intercourse).

Therefore, all people who were exposed to HIV or people who had a high-risk sexual encounter should be evaluated by a medical professional immediately. Time is of the essence.

After an exposure to HIV, post exposure prophylaxis (PEP) can prevent and HIV infection if it is provided within 72 hours. PEP consists of three (sometimes four) medications, two of which are included in one pill. The Centers for Disease Control and Prevention in Atlanta (CDC) recommends a combination of the drugs enofovir and emtricitabine (Truvada or Descovy), and either raltegravir (Isentress) or dolutegravir (Tivicay).  The medication is taken orally once or twice a day for 28 days and is highly effective to prevent an HIV infection.

Did you know? QuickMD can prescribe post-exposure prophylaxis online via telemedicine and prescribe Truvada or any of the other anti-viral HIV medications above online?
