Falciparum malaria and pregnancy.

R S Bray, M J Anderson

    Transactions of the Royal Society of Tropical Medicine and Hygiene
    |January 1, 1979
    PubMed
    Summary

    Pregnancy increases the risk of Plasmodium falciparum malaria, peaking early in gestation. Malaria prevalence in infants rises during the dry season, contrasting with adults.

    Area of Science:

    • Malariology
    • Maternal and Child Health
    • Epidemiology

    Background:

    • Pregnancy is associated with increased susceptibility to Plasmodium falciparum malaria.
    • Age influences malaria prevalence and density, with an overall decrease observed in both pregnant and non-pregnant individuals.
    • Seasonal variations impact malaria transmission dynamics.

    Purpose of the Study:

    • To investigate the relationship between pregnancy and Plasmodium falciparum malaria prevalence and density.
    • To examine age-related trends in malaria during pregnancy.
    • To analyze seasonal variations in antimalarial antibody levels and infant malaria.

    Main Methods:

    • Observational study analyzing malaria prevalence and density in pregnant and non-pregnant women across different age groups.
    • Assessment of malaria antibody levels in cord blood.
    • Comparison of infant malaria prevalence and density between wet and dry seasons.

    Main Results:

    • Pregnancy significantly increases Plasmodium falciparum malaria prevalence and density, with the effect being relatively constant across age groups.
    • Malaria risk during pregnancy peaks early and declines after mid-term.
    • Lower antimalarial antibodies were detected in cord blood during the high malaria season compared to the low transmission dry season; infants showed increased malaria in the dry season, unlike adults.

    Conclusions:

    • Pregnancy-associated malaria exhibits distinct age and gestational period patterns.
    • Seasonal variations influence both maternal antibody transfer and infant malaria exposure.
    • Understanding these dynamics is crucial for targeted malaria control strategies in pregnant women and infants.
