What does malarial mean?
Malarial is an adjective meaning relating to malaria, the disease caused by Plasmodium parasites and transmitted chiefly by infected mosquitoes. It may describe an infection, fever, parasite, mosquito, region, or other feature connected with the illness. The word is especially common in medical and geographical writing, where distinctions among malaria, malarial infections, and antimalarial treatments are important. Its historical interest lies in its connection with the name malaria itself: the Italian phrase mal’aria, meaning “bad air,” reflected an early theory that the disease was carried by unhealthy vapors. Although that explanation is obsolete, the word remains in regular use and clearly identifies conditions, organisms, or places associated with the disease.

Where does malarial come from?
Malarial was formed in English from malaria plus the adjective-forming suffix -al. The word malaria comes from Italian mal’aria, literally “bad air,” from malo, “bad,” and aria, “air.” This expression developed from the historical belief that malaria was caused by poisonous air in marshy regions. The disease was later understood to be transmitted by mosquitoes, but the original name and the derivative malarial remained in use.
