Americans really want to know their HIV risk during fellatio—even more so than during anal sex. These numbers are challenging to calculate and should therefore be considered rough estimates do not represent the risk of transmission from all exposures to HIV represent the average risk of transmission in the absence of biological factors that can increase risk such as STIs and a high viral load are most relevant to people in stable monogamous serodiscordant relationships These numbers may seem low but HIV transmission can occur after a single exposure the risk may be much higher if certain biological risk factors, such as STIs or a high viral load, are present as more exposures to HIV occur, the overall risk of transmission increases most HIV transmissions in Canada occur through unprotected anal and vaginal sex There are several ways of reducing the risk of HIV transmission from an exposure, such as post-exposure prophylaxis PEP , using antiretroviral treatment to reduce viral load , circumcision, treatment for STIs and vaginal conditions, or engaging in lower-risk activities. These included systematic reviews and meta-analyses that themselves included data from multiple studies. Then there is the concept of cumulative risk. Research suggests the risk of HIV transmission from receptive anal sex is 3 to 23 times higher than from insertive anal sex. Although the CDC estimates that nearly 1. James has an undergraduate degree in Microbiology and Immunology from the University of British Columbia. If these numbers are provided to clients, they should be accompanied by information that helps shed light on why the risk may be higher than it seems.
The data support a recent meta-analysis of all previous studies of the per-act risk of receptive anal intercourse to ejaculation for both heterosexuals and sex between men, which was estimated to be 1. It simply means that out of 70 exposures, on average, one will lead to HIV; bad luck might have it that the transmission occurs on the very first exposure. Research suggests the risk of HIV transmission from receptive anal sex is 3 to 23 times higher than from insertive anal sex. Receptive anal sex is riskier than insertive anal sex. Instead, it is a 92 percent reduction of the beginning risk. After looking at some 15, articles, they identified 14 relevant studies of per-act risk and 15 on modifying factors. It found that amongst men in high-income countries, unprotected anal intercourse with an HIV-positive insertive partner carried an estimated 0. If the guy pulls out before ejaculation, then the odds are 1 out of These updated estimates for both receptive and insertive anal sex are substantially higher than previous estimates 1. Only condoms can help protect against some other STDs. Using more than one of these options at the same time provides even greater protection. Another important concept to grasp is absolute risk what the risk actually is versus relative risk the percent change in the risk. Other factors lower risk. Transmission can occur after one exposure. The oft-cited numbers for the risk of HIV transmission take into account one instance of exposure. Lancet Infect Dis 9: One possibility is that less accurate estimates came from low-income countries e. If the beginning absolute risk is 50 percent, then PrEP reduces the risk to 4 percent; if the beginning risk is 20 percent, then PrEP lowers it to 1. They also looked at the protective effect of various prevention strategies. They are averages and do not represent the risk from all exposures to HIV through a certain type of sex. Sharing needles for injecting drugs had a risk of 63 per 10, exposures, while the risk from needle-sticks was 23 per 10, Some clients may see these numbers and think their risk of HIV transmission is low. This may present HIV and those living with it as the worst possible outcome imaginable, he notes, which is not only stigmatizing but often irrational and false since many people with HIV are, in fact, just fine. But they can be a good tool for understanding risk. Another recent study, described in the April 9 online edition of Clinical Infectious Diseases, looked in more depth at the risk of sexual transmission among heterosexual couples when the positive partner is on ART. But a young guy from the Midwest who looks negative?
