Pregnant Women and Malaria
QUESTION Why are pregnant women and children at the highest risk of getting malaria? ANSWER The reason why pregnant women and children are at greater risk of contracting malaria is due to their reduced levels of immunity.

It has to do with the life cycle of the malaria parasite. When a mosquito bites a human host, it injects … [Read more...]
