Malaria is a vector-borne infectious disease that is widespread in tropical and subtropical regions. It infects between 300 and 500 million people every year and causes between one and three million deaths annually, mostly among young children in Sub-Saharan Africa. Malaria is not just a disease commonly associated with poverty, but is also a cause of poverty and a major hindrance to economic development.

Malaria is one of the most common infectious diseases and an enormous public-health problem. The disease is caused by protozoan parasites of the genus Plasmodium. The most serious forms of the disease are caused by Plasmodium falciparum and Plasmodium vivax, but other related species (Plasmodium ovale, Plasmodium malariae, and sometimes Plasmodium knowlesi) can also infect humans. This group of human-pathogenic Plasmodium species are usually referred to as malaria parasites.

is a deseas widely spreaded in the tropical regions,but the name (malaria)is the name of the first scientist who analysed the disease

Malaria is a disease caused by a unicellular organism called protozoan, more specifically sporozoa. This little organism lives in mosquito saliva and it can be contracted when a mosquito, that has been infested by sporazoa, bits you. The unicellular organism will then gain entry into the body and causes several symptoms that are called Malaria.
