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.

Compared to circumcised men, uncircumcised men are more than twice as likely to acquire HIV-1 each time they have unprotected sex with an infected woman, according to a team of researchers in the US and Kenya. The study—the first to measure infectivity, or the probability of HIV-1 transmission per sex act, in a context of multiple partnerships—also found that infectivity among men, whether circumcised or not, who have several female partners is many fold higher than estimates based on monogamous HIV-1 discordant couples J Infect Dis , : — Jared Baeten of the University of Washington in Seattle and his colleagues calculated infectivity from data collected during a 4-year prospective study of male employees of six trucking companies in Mombasa, Kenya.

Ninety-five of the men were uncircumcised. In quarterly check-ups at a mobile research clinic that visited the companies on a weekly basis, each participant reported his sexual behavior with wives, casual partners and prostitutes during the previous 3 months. During the study, 11 uncircumcised men and 32 circumcised men acquired HIV.

On average, the men had sex 4. No participants reported sexual activity with men. The researchers calculated significantly higher infectivity among the uncircumcised men even when ethnicity, religion, occupation, marital status and other criteria were considered.

In general, an uncircumcised man had a 1-in chance of becoming infected during heterosexual sex compared to a 1-in chance for a circumcised male. The overall probability of female-to-male HIV-1 transmission for a single act of sexual intercourse was 1— in —, based on all men in the study.

The figure is several times greater than infectivity estimates for serodiscordant couples in the US or Europe, which range from 1-in to 1-in However, it is much lower than the odds, ranging from 1-in to 1-in, of becoming infected due to a sexual encounter with prostitutes in Thailand or Kenya. The results could help explain the rapid spread of HIV in many areas of Africa, where multiple partnerships, heterosexual transmission and a lack of circumcision are common.

They may also lead to more realistic models of the HIV epidemic, especially those trying to estimate the future impact of vaccines and other interventions.

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

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.

HIV and Specific Populations

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. Also, semen may stay in the vagina for days, which increases exposure to the virus. When someone has a sexually transmitted infection STI like chlamydia, gonorrhea, or syphilis, the risk of getting or giving HIV increases significantly. These infections make it more likely for a person with HIV to shed the virus.

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.

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.

Harm reduction during a pandemic. Now more than ever, we need a safe supply of drugs. What do the latest studies tell us about this risk? And how should we interpret and communicate the results?

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.

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.
