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. 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.
These malarial parasites are carried by the female mosquito (anopheles species) and about 100 different species can transmit human malaria. When an infected mosquito bites a human, the parasites can enter the bloodstream and travel for about an hour before entering the liver and then multiplying. Between 6 to 16 days (depending on the species), the parasites reenter the bloodstream to invade and multiply inside red blood cells (RBCs). These infected RBCs rupture and released more parasites that infect and destroy further RBCs.
Placental infection is common in regions where malaria is endemic with women carrying their first pregnancy (primigravida). (More? Placenta - Abnormalities)

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.
- 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.
