Risk of hiv with anal sex-Against All Odds: What Are Your Chances of Getting HIV in These Scenarios? - POZ

After couple-years of follow-up and 77, acts of unprotected anal intercourse, no HIV transmission from HIV-positive partners took place and the researchers concluded that the risk of HIV transmission in these circumstances was effectively zero Rodger. If viral load is detectable, condomless anal intercourse is a highly efficient way of transmitting HIV, and it is considered a high-risk activity for both partners, although the exact degree of risk can depend on many factors. For each condomless act with an untreated HIV-positive partner, the risk of infection has been estimated at 1. However, it may be 10 to 25 times higher if the positive partner is recently infected. Studies have identified several other factors that further increase the risk of transmission.

  • This tool allows you to access information that is individually tailored to meet your needs.
  • Oral sex ranks very low on the list of ways HIV can be transmitted.
  • The risk of HIV through unprotected anal intercourse is seen to be extremely high, as much 18 times greater than vaginal intercourse.
  • The risk of getting HIV varies widely depending on the type of sexual activity.

The risk of HIV through unprotected anal intercourse is seen to be extremely high, as much 18 times greater than vaginal intercourse. The reasons for the increased risk are well known and include such factors as:. In their review of 16 different high-quality studies, researchers at the Imperial College and the London School of Hygiene and Tropical Medicine concluded that the per-risk act of HIV through condomless anal sex was roughly around 1.

The risk of transmission was further increased if the insertive partner was uncircumcised 0. By contrast, the per-partner risk —in which an HIV-positive person is in an exclusive relationship with an HIV-negative partner—painted a somewhat clearer picture for both the receptive and insertive partners. The ten studies reviewed were conducted only among gay or bisexual men and included neither the length of the relationship nor the frequency of condomless sex.

An analysis of the data was able to show that:. Current evidence has shown that the consistent use of antiretroviral therapy ART in the HIV-infected partner completely eliminates the risk of HIV transmission when viral activity is suppressed to undetectable levels. The studies, which ran from to , showed unequivocally that undetectable equals untransmittable in a real-world setting. Although these figures may suggest that condoms are no longer needed, neither TasP nor PrEP can prevent other sexually transmitted diseases.

Without complete viral suppression, TasP is rendered useless, placing the uninfected partner at risk.

To this end, the consistent use of condoms can prevent seven out of 10 transmissions through anal sex, according to the CDC. This provides yet another layer of protection when used with other safer sex practices. In order to minimize the risk of infection, PEP must be started as soon as possible, ideally within one to 36 hours of exposure.

Anal sex and the risk of HIV transmission | aidsmap

Community pharmacists: Underutilized resources in the HIV care team. Anal sex is a common practice among men who have sex with men, heterosexual men and women, and transgender individuals and is a known risk factor for HIV infection and transmission.

Therefore, it is important that education on HIV prevention includes accurate information on the fluids that can transmit HIV through this type of sex. If one of these fluids is excluded from prevention messaging, it could lead a client to underestimate their risk of HIV transmission. While there is no doubt that semen, pre-ejaculate pre-cum , and blood can contribute to the risk of HIV transmission through anal sex; it seems there is less clarity among frontline service providers on whether rectal fluid should also be included on this list.

This article looks at what rectal fluid is, whether or not it can contain and transmit HIV, and the implications for prevention education. Rectal fluid is the mucus that lines the rectum. Mucus is a slippery secretion produced by certain parts of our body known as the mucous membranes. These membranes are located at the entrances into the body and line the internal passages of many of our organs, including the gastrointestinal tract mouth, intestines and rectum , the vagina and cervix, and the foreskin and urethra.

Mucus has several functions. A major function is to protect the mucous membranes from germs bacteria and viruses. Mucus also contains substances that can — to some extent — kill germs. For some membranes, mucus also acts as a lubricant that prevents friction and tearing of the mucous membrane tissue when objects pass through them. For example, mucus in the vagina reduces friction during sexual intercourse and mucus in the gastrointestinal tract including the rectum facilitates the passage of food and feces.

Mucus in the rectum also helps reduce friction during anal intercourse. This is because these membranes are rich in immune cells, which are the cells that HIV likes to infect and replicate within.

As a result, mucus produced by an HIV-positive person can contain HIV although the virus can be present in varying amounts , which can potentially be transmitted to someone else. The mucous membranes of the rectum, and the mucus they produce rectal fluid , are no exception. The high concentration of immune cells means that the majority of HIV replication in someone with HIV may be happening in the gastrointestinal tract, including the rectum.

Research show that this type of anal sex can carry a significant risk of HIV transmission. In fact, the average risk of HIV infection through a single act of condomless insertive anal sex with an HIV-positive partner is slightly higher than through vaginal sex but much lower than if the HIV-negative person takes the receptive role during anal sex.

Rectal fluid undoubtedly contributes to the risk of HIV transmission through anal sex where the insertive partner is HIV negative. Both the urethra and foreskin are vulnerable to HIV infection. Rectal fluid may not be the only fluid involved in the risk of HIV transmission during this type of sex. If the lining of the rectum has been damaged in some way, blood may also be present in the rectum. However, rectal fluid is always present in the rectum unlike blood and, therefore, likely plays a greater role in the risk of HIV transmission.

It is important that HIV prevention messaging includes rectal fluid as one of the fluids that can contain and transmit HIV. If rectal fluid is excluded, it could lead an HIV-negative person who is the insertive partner during anal sex to underestimate their risk of HIV infection; or a person with HIV who is the receptive partner during anal sex to underestimate their risk of transmitting HIV.

Implications for HIV transmission and prevention Anal sex is a common practice among men who have sex with men, heterosexual men and women, and transgender individuals and is a known risk factor for HIV infection and transmission. Key messages It is important that HIV prevention messaging includes rectal fluid as one of the fluids that can contain and transmit HIV.

Inflammation in the rectum, caused by STIs or tearing, may increase the amount of virus in the rectal fluid and increase the risk of HIV transmission. Minimizing rectal inflammation through the use of lubricants lubes and management of STIs regular STI testing and, if needed, treatment for STIs may prevent increases in rectal fluid viral load. Lowering the viral load in the blood and rectal fluid through successful antiretroviral treatment eliminates the risk for sexual HIV transmission even when STIs are present.

Condoms, in combination with lube, are highly effective in preventing the risk of HIV transmission if used consistently and correctly. Condoms can also significantly reduce the risk of STI transmission.

Post-exposure prophylaxis and pre-exposure prophylaxis are both highly effective options for HIV-negative people to reduce their risk of HIV infection. PEP needs to be accessed as soon as possible, but within 72 hours, after an exposure and taken daily for 28 days.

PrEP needs to be taken daily, on an ongoing basis. Adherence to daily pill-taking is important for both to be effective.
