Background: We examined correlates of infant morbidity and mortality within the first 3 months of life among HIV-exposed infants receiving post-exposure antiretroviral prophylaxis in South Africa. Methods: We conducted a prospective cohort study of 848 mother–child dyads. Multivariable Cox proportional hazards models were used. Results: The main causes of infant morbidity were gastrointestinal and respiratory infections. Morbidity was higher with infant HIV infection (HR: 2.61; 95% CI: 1.40–4.85; p = 0.002) and maternal plasma viral load (PVL) >100 000 copies ml⁻¹ (HR: 1.87; 95% CI: 1.01–3.48; p = 0.048), and lower with maternal age <20 years (HR: 0.25; 95% CI: 0.07–0.88; p = 0.031). Mortality was higher with infant HIV infection (HR: 4.10; 95% CI: 1.18–14.31; p = 0.027) and maternal PVL >100 000 copies ml⁻¹ (HR: 6.93; 95% CI: 1.64–29.26; p = 0.008).
