Malaria Fact Sheet

Malaria is caused by a one-celled animal, or protozoan, called Plasmodium.

There are 4 types of human malaria;  the one in Palm Beach County reported in this news story has been identified as Plasmodium vivax.
The other species are P. falciparum, P. ovale, and P. malariae.

Malaria is transmitted to humans by the bite of a female Anopheles when she takes a blood-meal for the development of her eggs.  Male mosquitoes do not feed on blood.  Both males and females feed on plant nectar.

Malaria causes more than 300 million acute illnesses and at least one million deaths each year, mostly among young African children.

Malaria symptoms appear about 9 to 14 days after the infectious mosquito bite, although this varies with different Plasmodium species.

Malaria produces recurrent chills, fever, headache, vomiting and other flu-like symptoms. If drugs are not available for treatment of the parasites or if the parasites are resistant to them, the infection can progress rapidly to become life threatening.   Malaria kills by destroying red blood cells and by clogging the capillaries that carry blood to the brain (cerebral malaria).
