Are " undetectable" poz guys ZERO risk to other barebackers?

[Belfast-Bottom]

Hi guys, I've heard various reports that poz guys on medication with an "undetectable" status are incapable of infecting bottoms? Does anyone know how true this is? Anyone know of reputable studies?

[ptcumdump]

a study was done a couple of years ago in switzerland that concluded that hiv positive individuals whose infection is controlled by anti-retrovirals and have an undetectable viral load and no other std's pose no transmission risk to negative partners. the key to that of course is that people don't know for certainty at any given time whether their viral load is undetectable. poz people who do have other std's, particularly syphilis, tend to have a spike in their viral loads even with med therapy. that's why public health officials, especially in the us, are reluctant to say that it is "safe" to have unprotected sex with a positive partner if he/she has undetectable levels of the virus. also, as you probably know, undetectable doesn't mean NO virus--it means there are fewer copies than can be detected by traditional clinical testing methods (usually under either 40 or 45 copies).

As ptcumdump notes above "......undetectable doesn't mean NO virus...."

I doubt that any scientific study would say that there is zero risk of transmission of hiv+ from an undetectable poz guy. They would couch their language in terms of lower risk than someone who has a detectable virus, even if a very low one.

Short answer is that yes, poz guys on effective medication regimens with consistently undetectable viral loads seem to be highly unlikely to transmit HIV to their partners. It is not a guarantee, but the risks are very much reduced. Here is one report that is useful:

Another report from the recent CROI Conference:

There are two problems with researching this issue:

1) There has been relatively little research on the specific impact of successful antiviral treatment on HIV transmission. It is difficult to tease out the various factors and their relative importance that have contributed to a decline of new infections. Given that infection rates did not decline as much in the years prior to effective antiviral therapy (when prevention relied almost entirely on safer sex practices) as they have in the HAART era, it is logical to conclude that successful treatment has contributed to the greater decline in infection. This inference is not iron-clad, though there are good biological reasons for asserting the claim.

2) There is a degree of active hostility to any research that would provide evidence supporting any bareback sex, and especially between poz and neg partners. This makes research funding harder to secure, and makes dispassionate investigation and discussion difficult.

I was with a guy who took a razor blade and nicked my ass lips a couple of times before he fucked me. He was undetectable because of the meds he was on. Do you think he infected me? I have not been tested.

[RedPhillip]

Even with the prep this guy provided it is pretty unlikely you were infected. You don't mention how long ago this happened, but if it is more than three months ago and you haven't experienced any illness - like a really bad flu or cold - adds are strong that you did not pick up HIV from this guy. Not everyone experiences a conversion syndrome after infection, but it is fairly common. Testing is the only way to be sure one way or another.

Hey Bobbie- Wondering if you have since tested positive? - either from this experience, or from subsequent experiences getting fucked, possibly by guys who were not undetectable?

[bobbie]

Well, I haven't been tested since the guy nicked my ass lips and fucked me. I guess I don't really want to know. But man I would love to get fucked by you...damn man, you are HOT looking and if you are poz...I will travel to get your babies!!!

Bringing some sanity into this discussion, if you test HIV+, you are, at the very least, a carrier and probabaly toxic. From your last posting, why are you concerned. It reads like you are a chaser and you want to become HIV+. I'm not passing judgement. But, I mean, having a POZ guy use a razor blade to cut your ass, fuck you, and then wonder if you are HIV+...? DUH! The POZ man was looking to infect you and you were going along with it. Detectable or not, if a POZ man fucked you and there was any tearing (whether by razor blade or his big cock), my thinking is that there is a 95% probability you're POZ. After all, that is what you want...isn't it. Otherwise, why allow him to cut you anus.
