PrEP à l’Actuel N = 245 patients La majorité des patients recevant de la PrEP sont adherents au traitement et au suivi. Mais 23% arrêtent le tx, la moitié durant les premiers 3 mois. Une seule seroconversion, survenue durant les premiers jours du programme. Donc probablement avant le début du traitement. La PrEP n’a pas été reliée à une augmentation des comportements à risqué.
