Malaria disease is characterized by cycles of symptoms that last 4-8 hours and have 3 stages; a 15-to-60 minute cold stage when you shiver and feel very cold, a 2-6 hour hot stage when your fever may reach as high as 41oC and finally, a 2-4 hour sweating stage during which your fever drops rapidly. These cycles are called paroxysms. Explain why they typically happen in malaria patients based on the pathogen life cycle
