Malaria
Malaria is a vector-borne infectious disease caused by a protozoan parasite of the genus Plasmodium, which is transmitted from human to human by the bite of infected female Anopheles mosquitoes. There are four identified species of Plasmodium, namely, P. vivax, P. falciparum, P. ovale and P. malariae: P.falciparum being the most fatal one. The life cycle of Plasmodium inside human body begins with a series of asexual divisions in liver and then red blood cells. The sporozoites, injected by the infected female Anopheles mosquito, are carried to the liver, where they undergo asexual forms known as exoerythrocytic schizogony to form merozoites. When these infected liver cells burst, merozoites are released into the blood, where they invade red blood cells. After invading the erythrocyte, merozoite de-differentiates into a round trophozoite form. The young trophozoite or the ring stage grows substantially to form schizont. Finally, it undergoes 4-5 rounds of binary divisions during the schizont stage, producing 8-36 new merozoites that burst from the host cell to invade new erythrocytes, beginning another round of infection. This phase of the infection (erythrocytic schizogony) is responsible for malaria pathogenesis. The parasites multiply within red blood cells, causing symptoms that include symptoms of anemia (light-headedness, shortness of breath, tachycardia, etc.), as well as other general symptoms such as fever, chills, nausea, flu-like illness, and, in severe cases, coma, and death. This animation emphasizes on the life cycle of Plasmodium inside human host.

The female mosquito …
The female mosquito has a specialised apparatus to penetrate the skin of its victim. At the end of the slender proboscis, there are two pairs of cutting stylets that slide against one another to slice through the skin. Once through the skin, the mosquito’s proboscis begins probing for a tiny blood vessel. If it does not strike one on the first try, the mosquito will pull back slightly and try again at another angle through the same hole in the skin, so need no wound.
