Abstract
SUMMARY Acquired immunodeficiency syndrome is associated with considerable morbidity in infants and children. It is caused by human immunodeficiency virus (HIV) which can be transmitted vertically from mother to infant early in pregnancy. Transmission might also occur via breast milk. Although the exact transmission rate of HIV from mother to infant is not known, HIV can become a major threat to child survival. This threat is already present in Africa where high seroprevalences have been reported among infants and young children. Transmission via blood products is decreasing due to reliable methods of screening donors for HIV antibody. Where these tests are not available, parenteral transmission will increase the incidence of HIV infection. The clinical picture of HIV infection in children presents with failure to thrive, pulmonary interstitial pneumonitis, hepatosplenomegaly and recurrent bacterial infections. These are common manifestations of diseases prevalent in children in Africa where malnutrition and recurrent parasitic infections already cause immunosuppression. Recognition of the syndrome is therefore difficult. There is no available cure for HIV infection. Supportive treatment and relief of pain and suffering are the only means of management at present. Prevention of spread of the illness to infants and young children is therefore of paramount importance.
