The Female Mosquito
The Epidemiologic Triangle is a model that scientists have developed for studying health problems. It helps public health professionals understand infectious diseases and how they spread. The WHAT,Where, & WHO behind communicable diseases.
The mosquito vector does not suffer from the presence of the parasites
(i.e. may not get sick or have any outward signs/symptoms of illness from the parasite)

Agent
Agent: Malaria is the causing of the disease. A Protozoan that lives off other organisms, in some cases humans, a (microbe/ organism) too small to be seen with the naked eye. . ((CDC), 2016)
Environment
Where?
The environment that is favorable with perfect surroundings and conditions are the liver and red blood cells of humans and in the the female mosquito's salivary glands to the host that cause or allow the disease to be transmitted. . ((CDC), 2016)
Host
Who?
Hosts are organisms, usually humans or animals that are exposed to and harbor the disease. In the case of Malaria two hosts are necessary (the female mosquito and human). In humans, the parasites grow and multiply first in the liver cells and then in the red blood cells. The parasites grow inside the red cells and then destroys them releasing daughter parasites (merozoites) that continue the cycle by invading other red cells. The host can get sick, or may not get sick or have any outward signs of illness. . ((CDC), 2016)
