RELATIONSHIP OF MENSTRUAL CYCLING AND VAGINAL INFECTION IN FEMALE RHESUS MACAQUES CHALLENGED WITH REPEATED, LOW DOSES OF SIVMAC251

Varying susceptibility during menstrual cycling could be a factor for S(H)IV infection risk in female rhesus macaques. We retrospectively determined vaginal SIV infection time points relative to the menstrual cycle in a group of rhesus macaques (n=11) enrolled in an HIV transmission trial. Eight of nine rhesus macaques became infected around menstruation time.
