Maternal and neonatal outcomes after infection with monkeypox virus clade I during pregnancy in DR Congo: a pooled, prospective cohort study.
Abstract
Background Monkeypox virus (MPXV) has been linked to vertical transmission, but systematic data are scarce. We aimed to describe the sociodemographic, clinical, and virological characteristics and assess the frequency and determinants of adverse outcomes in pregnant women with MPXV clade I infection.Methods In this prospective cohort study, we pooled data from three cohort studies (MBOTE-SK, PREGMPOX, and Uvira mpox) and one randomised controlled trial (PALM007) conducted in the South Kivu, Maniema, and Sankuru provinces of DR Congo between Dec 29, 2022, and June 20, 2025. Pregnant women and adolescent girls with a PCR-confirmed diagnosis of mpox were followed up throughout hospitalisation for mpox, delivery, and until discharge during the postpartum period. We extracted data on sociodemographic characteristics, MPXV exposure, clinical and obstetric presentation, and laboratory results. In a univariable analysis, we examined factors associated with the following adverse outcomes: spontaneous or missed abortion (
