Vaginal Sex and HIV Risk
Several factors can increase the risk of HIV in women. For example, during vaginal or anal sex, a woman has a greater risk for getting HIV because, in general, receptive sex is riskier than insertive sex.
HIV is spread through the blood, pre-seminal fluids, semen, vaginal fluids, rectal fluids, or breast milk of a person who has HIV. Age-related thinning and dryness of the vagina may also increase the risk of HIV in older women. A woman's risk of HIV can also increase if her partner engages in high-risk behaviors, such as injection drug use or having sex with other partners without using condoms.
However, birth control and pregnancy are two issues that can affect HIV treatment in women. Birth control Some HIV medicines may reduce the effectiveness of hormonal contraceptives, such as birth control pills, patches, rings, or implants. Women taking certain HIV medicines may have to use an additional or different form of birth control. In general, pregnant women with HIV can use the same HIV regimens recommended for non-pregnant adults—unless the risk of any known side effects to a pregnant woman or her baby outweighs the benefits of a regimen.

Visit coronavirus. You can only get HIV by coming into direct contact with certain body fluids from a person with HIV who has a detectable viral load. These fluids are:. For transmission to occur, the HIV in these fluids must get into the bloodstream of an HIV-negative person through a mucous membrane found in the rectum, vagina, mouth, or tip of the penis ; open cuts or sores; or by direct injection.
Harm reduction during a pandemic. What do the latest studies tell us about this risk? And how should we interpret and communicate the results? To do this effectively, a group of HIV-negative individuals need to be followed over time and their exposures to HIV—both the number of times they are exposed and the types of exposure—need to be tracked. As you can imagine, accurately tracking the number of times a person is exposed to HIV is very difficult.
HIV and Specific Populations
During a median follow-up period of 1. No HIV transmissions occurred. The investigators concluded that the risk of HIV transmission through vaginal intercourse in these circumstances was effectively zero Rodger. When HIV is not suppressed by antiretroviral treatment, vaginal intercourse without a condom is a highly efficient route of HIV transmission because high concentrations of HIV can occur in semen and vaginal fluids, and because the genital tissues are very susceptible to infection. This allows the virus to reach the inner vaginal lining, which is rich in immune cells through which it can establish systemic infection. Cells located beneath the surface of the cervix are particularly vulnerable to HIV infection, especially during adolescence and during a woman's first pregnancy, or due to infection with human papillomavirus and chlamydia. A meta-analysis of studies of heterosexual HIV transmission found that, in high-income countries prior to the introduction of combination therapy, the risk per sexual act was 0. The risk was 0. However, these rates were considerably higher when the source partner was in either the very early or the late stage of HIV infection, when one partner had a sexually transmitted infection that causes genital sores, and also in studies done in lower-income countries Boily.

What Is the Risk of HIV From Vaginal Sex?
Vaginal sex intercourse involves inserting the penis into the vagina. Some sexual activities are riskier than others for getting or transmitting HIV. Activities like oral sex, touching, and kissing carry little to no risk for getting or transmitting HIV. In addition to HIV, a person can get other sexually transmitted diseases STDs like chlamydia and gonorrhea from vaginal sex if condoms are not used correctly. Even if a condom is used, some STDs can still be transmitted through skin-to-skin contact like syphilis or herpes. Hepatitis A and B can also be transmitted through vaginal sex. If one has never had hepatitis A or B, there are vaccines to prevent them. A health care provider can make recommendations about vaccines.
