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.

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 serodiscordant couple is one in which one partner has HIV and the other has not. Many people dislike this word as it implies disagreement or conflict. Alternative terms include mixed status, magnetic or serodifferent. A range of complex mathematical techniques which aim to simulate a sequence of likely future events, in order to estimate the impact of a health intervention or the spread of an infection.

The researchers recruited HIV-negative Kenyan men from six truck companies in Mombasa between and Every three months, the men were asked about the number of sex partners, the number of sex acts carried out with three different types of partner wives, casual partners and prostitutes and condom use. The men were also tested for HIV-1 at every visit. The investigators estimated the probability of HIV transmission per sex act for each man using a mathematical model.

During a median follow-up of days, 43 men became HIV-positive. Eleven of these were uncircumcised and 32 were circumcised. Rates of unprotected sex were also high. This risk was 2. To check for the influence of religious or cultural differences on their results, the researchers repeated their analysis after removing the Muslim men, who are almost all circumcised, finding that this had little effect on their conclusions.

Similarly, omission of the data from men of the Luo ethnic group, who have low levels of circumcision, did not affect their conclusions. Re-analysis after removal of either of these assumptions did not cause any change in the observed trends. Moreover, our results strengthen the substantial body of evidence suggesting that variation in the prevalence of male circumcision may be a principal contributor to the spread of HIV-1 in Africa.

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.

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.

Vaginal Sex and HIV Risk

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.

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.

Even if a condom is used, some STDs can still be transmitted through skin-to-skin contact like syphilis or herpes.
