Introduction

Malaria (plasmodium falciparum)

About 10,000 women and 200,000 babies die annually because of malaria in pregnancy, which can cause miscarriages, preterm births, and low-birth-weight births.[1] There are about 156 species of Plasmodium which infect different vertebrate species. In humans there are four types of malaria caused by the protozoan parasite Plasmodium falciparum (main), Plasmodium vivax, Plasmodium ovale, Plasmodium malariae.

Placental infection is common in regions where malaria is endemic with women carrying their first pregnancy (primigravida).

Some Recent Findings

  • Plasmodium vivax malaria[2] "Up to 40% of the world's population is at risk for Plasmodium vivax malaria, a disease that imposes a major public health and economic burden on endemic countries. Because P. vivax produces latent liver forms, eradication of P. vivax malaria is more challenging than it is for P. falciparum."

Placental Malaria

Pregnant women have an increased susceptibility to malaria infection. Malarial infection of the placenta by sequestration of the infected red blood cells leading to low birth weight and other effects.

Placental volume - second trimester[3]
  • Several infective agents may cross into the placenta from the maternal circulation, as well as enter the embryo/fetal circulation. \
  • Pregnant women have an increased susceptibility to malaria infection.
  • Malarial infection of the placenta by sequestration of the infected red blood cells leading to low birth weight and other effects.
