Is malaria contagious?

Malaria is not spread from person to person (except in pregnancy as noted below below) but can be spread in certain circumstances without a mosquito. This occurs rarely and is usually found in a transmission from the mother to the unborn child (congenital malaria), by blood transfusions, or when intravenous-drug users share needles.

What is the incubation period for malaria?

Following the mosquito bite, there is about a seven- to 30-day period before symptoms appear (incubation period). P. falciparum usually has a short incubation period.

What causes malaria?

Parasites of the genus Plasmodium cause malaria. Although there are many species of Plasmodium, only five infect humans and cause malaria.

P. falciparum: found in tropical and subtropical areas; major contributor to deaths from severe malaria

P. vivax: found in Asia and Latin America; has a dormant stage that can cause relapses

P. ovale: found in Africa and the Pacific islands

P. malariae: worldwide; can cause a chronic infection

P. knowlesi: found throughout Southeast Asia; can rapidly progress from an uncomplicated case to a severe malaria infection
