Introduction: Achieving the goal of “zero new human immunodeficiency virus (HIV) infections by 2030” requires the elimination of HIV transmission within serodiscordant couples. In Benin, the phenomenon of HIV serodiscordance remains poorly documented. Objective: the aim of this study was to determine the prevalence of HIV serodiscordance and its associated factors among infected couples in the city of Parakou. Study Framework and Method: This was a descriptive cross-sectional study with an analytical focusing on qualitative and quantitative plans. It was carried out on thirty approved sites in the city of Parakou between July and December 2022. We used a non-exhaustive convenience sample of people living with HIV (PLHIV) whose partner’s status was known. Data collection took place in two phases: an interview phase during which sociodemographic, economic, behavioral and marital/social data were collected. The second phase focused on clinical and therapeutic data which were collected from the patients’ personal records. Results: A total of 417 study subjects were recruited. The average age (SD) of the subjects was 38.17 (±10.25) years [37.19 - 39.16]. Females accounted for the largest proportion (79.62%). Most respondents (74.11%) were married. Monogamous unions were the most frequent, involving 67.87% of participants, most of whom (44.60%) had been infected for between 1 and 5 years. Couples in union for less than 10 years were the most numerous (218 people or 52.28%). The respondent was head of household among only 140 respondents (33.57%) of which 84 men (60.00%) and 56 women (40.00%). Female heads of household were mainly divorcees and widows. Around 75% of PLHIV had monthly incomes of less than 50,000F CFA (81.16 USD). Prevalence of HIV serodiscordance was 71.70%. It was 70.91% [65.54% - 76.28%] at care sites and 73.24% [65.95% - 80.52%] at sites involved in preventing mother-to-child transmission (PMTCT sites). Potential predictors of HIV serodiscordance were: household head status; serostatus of last child; duration of relationship; multiple and occasional sexual partners; sharing serostatus with spouse; duration of couple relationship; spouse’s extramarital relationships and strained relations with children. Conclusion: Response strategies against the HIV pandemic need to be reshaped to better supervise the follow-up of HIV serodiscordant couples in the city of Parakou specifically and in Benin in general.
