The second large study to look at whether people with HIV become non-infectious if they are on antiretroviral therapy (ART) has found no cases where someone with a viral load under 200 copies/ml transmitted HIV, either by anal or vaginal sex.Statistical analysis shows that the maximum likely chance of transmission via anal sex from someone on successful HIV treatment was 1% a year for any anal sex and 4% for anal sex with ejaculation where the HIV-negative partner was receptive; but the true likelihood is probably much nearer to zero than this. When asked what the study tells us about the chance of someone with an undetectable viral load  transmitting HIV, presenter Alison Rodger said: “Our best estimate is it’s zero.”
I’ve seen an article on this going around Tumblr, but I wanted to post the actual original article. I wanted to find the study, but I can’t find a place to access it and this article is actually pretty in depth for us medblr folks!
Overall, this is awesome news. Hopefully there will be additional research to support this!
1) Seems gay men shift in and out of risk levels pretty fluidly. 2) Having an income above $20,000 a year actually makes gay men MORE LIKELY to be at high risk for HIV infection. 3) In addition, being white, as opposed to being black or hispanic was linked to an increase in high-risk behavior.
“The main news is that in the PARTNER Study so far there have been NO TRANSMISSIONS within couples from a partner with an undetectable viral load, in what was estimated as 16,400 occasions of sex in the gay men and 14,000 in the heterosexuals.” - From AIDSmap’s “No-one with an undetectable viral load, gay or heterosexual, transmits HIV in first two years of PARTNER study”
The use of HIV antiretrovirals as pre-exposure prophylaxis to prevent the transmission of the virus before it manifests is proven to work, and apparently vastly supported in the medical community. But when it comes to actually making the decision with patients, most docs back out. Is it an education or moral flaw?
