Malaria

Abstract

Malaria is a subtropical and tropical protozoan infection that accounts for nearly half a million deaths each year. Most deaths occur in sub-Saharan Africa and are caused by Plasmodium falciparum. The least studied of the five Plasmodia species that cause malaria, P. knowlesi, along with P. vivax cause life-threatening disease, mostly in Southeast Asia. Children, pregnant women, and non-immune travellers to endemic countries are most vulnerable to severe malaria. Cerebral malaria and anaemia are complications that results in neurological deficit and death if treatment is delayed or inappropriately administered. Rapid diagnostic tests have emerged as accurate and reliable means to diagnosing malaria at point-of-care.
