Impact of Containment and the Current Epidemic on the Sexual Risk-taking of People Using PrEP to Prevent HIV Infection.

People using PrEP to prevent HIV infection have sexual risk-taking behaviors that motivated the prescription of PrEP. Both containment and the current epidemic may affect the sexual behavior of people using PrEP and the risk of acquiring STIs. Hypotheses regarding the impact of the current epidemic-motivated confinement and its gradual lifting are as follows: * A decrease in sexual risk-taking during the confinement period, followed by an increase when the confinement is lifted. * An increase in sexual violence and the use of psychoactive substances. * An impact on PrEP monitoring and compliance. * An increase in the incidence of STIs when the confinement is lifted.
