I’m undetectable and worried about transmission to my partner..
I’m a positive gay male dating for 5 and 1/2 yrs undetectable for 5 yrs on meds since diagnosis. My viral load less than 48 copies. My partner gave me oral sex while showering and I’m worried. I read about the partner study. What’s the chances of him getting it. I’m always paranoid about him getting it from me.
Thanks for your question.
It’s normal to worried about passing on HIV to your partner. However, ART is very effective at reducing the risk of transmission.
If your viral load in undetectable (below 50 copies), the risk is very low and may even be zero.
This is based on results from the PARTNER study. In this study there were no HIV transmissions after more than 58,000 times when couples had sex without condoms. See our Q and A and on the PARTNER study for more.
This does not mean that it is impossible to transmit HIV with an undetectable viral load but it is very unlikely and the results are strong enough to not have to use condoms for preventing transmission.
