Anopheles-borne cyclic fever with hemolysis
muh-LAIR-ee-uh
High-yield clue
Cyclic paroxysms of fever, chills, and sweats with hemolytic anemia after an Anopheles bite is the classic malaria clue; P. falciparum is the most severe.
Overview
A mosquito-borne protozoal illness from Plasmodium species, studied for periodic paroxysmal fever, timing tied to the red-cell cycle, and falciparum complications.
Classification

- Ring forms and banana-shaped gametocytes (falciparum)
- Rapid antigen (HRP-2) test concept
Associations
- Anopheles mosquito transmission
- Tertian and quartan fever periodicity vocabulary
- Severe or cerebral malaria and blackwater fever (falciparum)
- Relapse from dormant hypnozoites (P. vivax and P. ovale)
Commonly confused with
