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.

This study follows up on an earlier study by the same authors examining per-act heterosexual HIV transmission probabilities. It is a systematic review and analysis of all available study data related to the likelihood of heterosexual HIV transmission. The authors reviewed 43 published studies conducted in various countries that reported per-act heterosexual HIV-1 transmission probability estimates.

The authors concluded that the average male to female risk of HIV transmission is. The authors' three objectives were to provide summary estimates of HIV-1 transmission probabilities per heterosexual contact; do in-depth single variable and multivariable analysis to explore the reasons for different study results; and estimate the role of risk factors such as viral load and STIs on the likelihood of transmission.

The authors point out that putting a number on the actual likelihood of HIV transmission in a single sexual act is difficult to measure. The actual transmission to a partner, the number of unprotected sex acts, the length of the partner's exposure to HIV, and other potential co-factors among the people who participate in a study about their sex acts are rarely completely known and there are unreported factors, such as some participants actually having other STIs, which could affect the accuracy of studies.

Of course, this is likely true of most, if not all, studies that attempt to base conclusions on what people report about their sex lives. The authors found that, overall, female-to-male. Other findings showed that there were higher estimates of HIV transmission during receptive anal sex 1.

There also were larger estimated risks of HIV transmission for sexual acts during the early 9. Skip to main content. Heterosexual risk of HIV-1 infection per sexual-act: systematic review and meta-analysis of observational studies, Marie-Claude Boily et al. Het risk of HIV trans-Boilyetc

How Is HIV Transmitted?

HIV is not spread through saliva, by touching a person or object, or by insect bites. In the United States, the most common ways for HIV to spread are unprotected sex and injection drug use. Risk of HIV transmission increases if there are open sores on the genitals of the person receiving oral sex, or mouth sores, gum disease or recent dental work for the person giving oral sex.

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.

HIV and Specific Populations

Vaginal sex is one of the primary ways a person can become infected with HIV. According to the U. Globally, the figures are even more dismaying. While the sexual transmission of HIV in the U. This is especially true in Africa where most new infections are among heterosexuals. In these populations, vaginal sex is the predominant route of infection. From a purely statistical standpoint, anal sex is considered the highest risk activity with an almost fold greater risk of infection compared to vaginal sex. But this assessment is somewhat misleading, at least from an individual perspective.

Against All Odds: What Are Your Chances of Getting HIV in These Scenarios?

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.

When it comes to contracting HIV, some acts are riskier than others. Here are the HIV transmission rates by type of exposure.

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.

Q: What are the chances of a man being infected after condomless sex with a woman who has HIV? In general, the risk of a man getting HIV from an HIV-positive woman during vaginal intercourse in the United States is low--probably less than 1 of 1, exposures will result in actual infection. This risk may be higher depending on certain factors, such as whether the woman is having her period or whether the man is uncircumcised, and it also may be higher in poor countries. Of course, there is no risk of getting HIV from a woman unless she has HIV, so it's good to talk about this with any potential sex partner. After all, she may have the same thoughts or concerns about whether YOU have HIV, but also might not bring up the subject.

A person with HIV can pass the virus on to others even if they don't have any symptoms. women who have unprotected sex with men who have sex with men; people who HIV isn't passed on easily from one person to another.

Male circumcision reduces the risk of infection with HIV-1 from female sexual partners by more than twofold, according to a study of Kenyan men published in the 15 th February edition of The Journal of Infectious Diseases. Although previous studies have found similar trends, this investigation is the first to assess the risk of transmission per sex act in an area where multiple sexual partners and a lack of male circumcision are common, and to take religious and ethnic differences into account. Although sub-Saharan Africa has a high prevalence of HIV-1 infection, the spread of the virus has not been uniform across the region. To resolve these issues, investigators from Kenya and the United States carried out a prospective study of HIV infection and sexual behaviour in a cohort of Kenyan men. The surgical removal of the foreskin of the penis the retractable fold of tissue that covers the head of the penis to reduce the risk of HIV infection in men.
