Abstract
This article provides a synthesis of clinical trial data with an aim to deduce the timing of mother-to-child transmission of HIV-1. Because transmission of the infection to the infant through breastfeeding is one of the main challenges in fighting paediatric HIV/AIDS in the developing world, we present separate estimates for the timing of HIV transmission for non-breastfeeding and breastfeeding populations. Our estimates predict that, for non-breastfeeding populations, 50% of HIV infections are transmitted to the infant at the very end of pregnancy, near to the time of labour. For breastfeeding populations, the postnatal period accounts for most of the HIV infections transmitted to the infant. We discuss the potential benefit of exclusive breastfeeding for the first 6 months of life as a policy to decrease the magnitude of HIV transmission. Furthermore, we present the hypothesis, based on recent research findings of viral latency, that the time when a fetus initially encounters the virus might not be when infection is established. We discuss the implications of this hypothesis and how it could lead to new interventions for the prevention of mother-to-child HIV transmission.
