- Malaria typically produces a string of recurrent attacks, or paroxysms, each of which has three stages—chills, followed by fever, and then sweating.
- Along with chills, the person is likely to have headache, nausea, and vomiting.
- Within an hour or two, the person’s temperature rises, and the skin feels hot and dry. Then, as the body temperature falls, a drenching sweat begins. The person, feeling tired and weak, is likely to fall asleep.
- The symptoms first appear some 10 to 16 days after the infectious mosquito bite and coincide with the bursting of infected red blood cells.
- When many red blood cells are infected and break at the same time, malaria attacks can recur at regular time periods—every 2 days for P. vivax malaria and P. ovale, and every 3 days for P. malariae.
