RESUMEN
Mother-to-child transmission is a continuing source of new HIV infections in South Africa. The paper posits that insight into the socio-cultural; behavioural; environmental and economic factors that sustain the HIV epidemic is as important as understanding the biological causes of the disease when planning and implementing interventions to prevent and reduce perinatal transmission. Furthermore; understanding the pregnancy intentions of individuals in areas of endemic HIV/AIDS is vital for providing the best care for individuals who are HIV-positive.

Included among these are interventions for prevention of unwanted pregnancy; prevention of transmission of HIV; protection of the infant; and protection of the mother
