Which type of fever is malaria?
The classic symptom of malaria is paroxysm—a cyclical occurrence of sudden coldness followed by shivering and then fever and sweating, occurring every two days (tertian fever) in P. vivax and P. ovale infections, and every three days (quartan fever) for P. malariae.

What are the three stages of malaria?
When the parasite infects animals, it attacks in three stages: It goes into liver cells first, then enters blood cells, and finally forms gametes that can be transmitted to mosquitos. Most treatments primarily target parasites in the blood stage, which causes malaria’s symptoms—fever, vomiting, and coma. Stuart L.
