IPA: /ˌæntiˈmeɪləriə/
KK: /ˌæntiˈmeɪlɚiə/
Describing something that helps to prevent or treat malaria, a serious disease caused by parasites transmitted through mosquito bites.
The antimalaria drug was effective in treating the patient's infection.
Antimalaria is formed from "anti-" (meaning against) and "malaria" (from Italian *mal'aria*, meaning bad air). The word refers to something that works against malaria, which was historically thought to be caused by bad air.
Think of 'anti-' meaning against, and 'malaria' referring to bad air — this helps you remember that antimalaria means something that fights against the effects of malaria.
