LOL do it now? Even IF i was infected and its a very big IF...its not going to show up immediately. You obviously are not very knowledgeable about HIV transmission, so I wont be too concerned about your advice. And if I now was pos taking anti virals now is going to prevent it? LOL. NO,,its going to suppress it.
I think Fightinghunger is referring to
PEP (Post-Exposure Prophylaxis) where anti-retrovirals are prescribed for a month to prevent hiv establishing itself. Such treatment needs to be commenced within 72 hours of exposure (like, now). It is preceded by a fast hiv test to check that you weren't already infected.
Free PEP is available at sexual health clinics and emergency departments of hospitals in the UK. I don't know the availability or cost of it in the USA.
Your friend had an undectable
viral load at the time of his last blood tests. The tests were on his blood, not his other body fluids. Undetectable does not mean non-existant, it means low numbers of viral particles. That situation may have changed since his last test. Poor
adherence to his drug regime, or another infection, can result in an increased viral load. Plus eventually his hiv will become resistant to his current medication.
Viral load testing is used by his doctors to judge the efficacy of his treatment and as a predictor of the likelihood of his developing aids-related illnesses, and not as a measure of his transmissability.
Intuitively, I would think that the chances of transmission are lowered if the blood viral load is low, but there have been very few studies to demonstrate that. One widely-quoted "concensus" from Swiss experts that low load = low transmission was based on a study of
heterosexual Ugandan sero-discordant
couples where
no antiretroviral medication was prescribed, so this can't be confidently applied to sexually active gay men on medication.
As a hiv-negative person, the onus is entirely on you to protect yourself from a life-long and life-changing infection. You can't rely on the opinions of others based on the results of imprecise blood tests that could have been conducted months ago.
Yes, the odds are low that this single incident has resulted in infection and I'm not just trying to freak you out. But the consequences of contracting hiv are so serious that it is worth minimising the risks as much as possible. Which still means condoms for fucking! Especially as the most infectious individuals are the undiagnosed.
So, if you're still within the three-day window you should consider PEP. It will lower the already low chances considerably - it's estimated to have a 70% success rate in preventing infection.
