Trained community health workers (CHWs) will conduct home visits every 2 months to update the list of married women of reproductive age (13-49 years). At every visit, the women under surveillance will be asked about the date of the first day of the last menstrual period (LMP) and the date is recorded. Pregnant women is identified based on the missed period. All pregnant women are eligible for enrollment and will be consented for their participation and that of their newborn infant in the study. A detailed verbal informed consent process is undertaken to ensure that participating women understand the nature of the home-based infant surveillance that would begin shortly after newborn delivery.
