Origin of malaria
1730–40; < Italian, contraction of mala aria bad air
an infectious disease characterized by recurring attacks of chills and fever, caused by the bite of an anopheles mosquito infected with any of four protozoans of the genus Plasmodium (P. vivax, P. falciparum, P. malariae, or P. ovale)
1740, from Italian mal'aria, from mala aria, literally "bad air," from mala "bad" (fem. of malo, from Latin malus; see mal-) + aria "air" (see air (n.1)). Probably first used by Italian physician Francisco Torti (1658-1741). The disease, now known to be mosquito-borne, once was thought to be caused by foul air in marshy districts. Replaced native ague.
An infectious disease characterized by cycles of chills, fever, and sweating, caused by the parasitic infection of red blood cells by a protozoan of the genus Plasmodium, which is transmitted by the bite of an infected female anopheles mosquito.jungle feverpaludismswamp fever
