title: A seroepidemiological study to evaluate the role of passive maternal immunity to malaria in infants.
abstract: Parasitaemias and loss of natural antibody to Plasmodium falciparum were studied in 104 infants in a highly endemic area of Papua New Guinea. There were 4 cases of congenital infection. Most infants lost malaria-specific immunoglobulin G (IgG) between 4 and 7 months (median = 21 weeks). 73% of heavy infections developed in infants without detectable antimalarial IgG. Infections in the presence of antimalarial IgG were asymptomatic and had scanty parasitaemias.
