Factors associated with partner notification of STIs in men who have sex with men on PrEP in France: a cross-sectional substudy of the ANRS-IPERGAY trial.

Unsafe sexual encounters with people other than main partners and street drugs use were two sociobehavioural factors identified, respectively, as a barrier to main PN and a motivator for casual PN, in a sample of high-risk MSM. These results provide an insight into current PN practices regarding STI in France and might inform future decisions about how to define feasible and acceptable PN programmes.
