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. Condoms and dental dams reduce the chance of giving or getting HIV during oral sex. Compared to the vagina, there are fewer areas on the penis where the virus can enter the body. The virus can also enter through cuts or sores on the penis.

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. Consider for a moment that women are three to four times more likely to get HIV from men than the other way around. Conversely, there are some men who are far more likely to get HIV than others. Vulnerabilities vary by individual, so assessing what the real risk of vaginal sex requires a better understanding of the factors that place some women and men at greater risk than others. The risk of HIV from unprotected vaginal sex is higher among women for a number of reasons.

From a physiological standpoint, the tissues of the vagina epithelium are far more susceptible to HIV than those of the penis. HIV is able to pass through these tissues when the immune system recognizes the invading virus and send defensive cells called macrophages and dendritic cells to "grab and drag" them through the lining to be destroyed. By doing so, the body helps facilitate its own infection. And, because the surface area of the vaginal epithelium is far greater than that of the male urethra, the opportunity for infection is increased, often exponentially.

Other physiological vulnerabilities include:. While the daily use of an HIV drug called pre-exposure prophylaxis PrEP can dramatically decrease the risk of HIV in an uninfected partner, there is evidence that works less well in women.

Research published in suggests the level of the active drug molecule in vaginal tissue isn't near as high as in rectal tissue. None of this, of course, takes into account any of the social vulnerabilities that can place women at increased risk. These include sexual violence in relationships which not only steals a woman's chance for self-protection but can result in damage to delicate vaginal tissue.

All of these contribute to higher rates of HIV in women. The fact that men are less susceptible to HIV than women shouldn't underplay the fact that they also have vulnerabilities that can increase their personal risk of infection. We know, for example, that an uncircumcised penis can facilitate infection due to the bacteria-rich environment beneath the foreskin.

Sexually transmitted infections and genital tract infections can further increase the risk of HIV. It creates a double standard that can place a man at greater risk of HIV by associating virility with multiple partners or other high-risk behaviors.

Among them:. A high viral load during acute infection the stage immediately following exposure is associated with an increase in HIV risk. Drinking alcohol or taking drugs can lower inhibitions and affects a person's ability to make safe choices, such as using condoms or remaining adherent to HIV drug therapy.

From the perspective of per-exposure risk the chance of getting HIV from a single sexual act , risk can vary based on gender, the viral load of the HIV-positive partner, and even the part of the world you live in.

These figures do not take into account any other factors that can increase risk, including the presence of an STI, injecting drug use, or a co-existing infection like hepatitis C. Assessing your personal risk for HIV should never be a numbers game. Doing so may entirely erase the risk of transmission.

And don't forget the tried-and-true condom, which is associated with a decrease in risk if used correctly and consistently. By formulating a holistic approach to prevention, you can continue to enjoy a healthy sex life while protecting yourself or a loved one from the risk of HIV.

Vaginal Sex and HIV Risk

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.

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.

HIV and AIDS - Basic facts

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.

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

HIV stands for human immunodeficiency virus. HIV is a retrovirus that infects cells of the human immune system mainly CD4-positive T-cells and macrophages—key components of the cellular immune system and destroys or impairs their function. Infection with this virus results in the progressive depletion of the immune system, leading to immunodeficiency. The immune system is considered deficient when it can no longer fulfil its role of fighting off infection and diseases. People with immunodeficiency are much more vulnerable to a wide range of infections and cancers, most of which are rare among people without immunodeficiency.

HIV and Specific Populations

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.

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. A type of longitudinal study in which people join the study and information is then collected on them for several weeks, months or years.

What Is the Risk of HIV From Vaginal Sex?

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.

Dec 8, - These microscopic tears can create a route for HIV-containing fluids, such as semen, to enter the body. Male vs. female partners. When having.

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.
