Parasites

 

A Parasite is an organism that lives on or in a host and gets its food from or at the expense of its host. Parasitic infections cause a tremendous burden of disease in both the tropics and subtropics as well as in more temperate climates.

 

Of all parasitic diseases, Malaria causes the most deaths globally, largely in rural areas of low-income countries. These diseases extract a large toll on endemic populations, including lost ability to attend school or work, retardation of growth in children, and impairment of cognitive skills and development in young children.
