Study population
HIV presenting
﻿﻿The study population was all pregnant women with HIV presenting at a study site (MCH clinics) to begin prenatal care. This included women who were newly diagnosed with HIV when presenting for prenatal care (treatment naïve) as well as pregnant women with HIV already on ART (treatment-experienced) when presenting for prenatal care. HIV testing for pregnant women presenting for prenatal care is high in Kenya (> 90% national from 2013; > 95% in 2018) [
