Common diseases: pathogens and life cycles
Why this is asked: By parasitology's own definition, the mosquito, not the human, is Plasmodium's definitive host, because the sexual stage of the parasite's life cycle happens inside the mosquito; the human is only the intermediate host, where the asexual cycle runs. The recurring chills and high fever are timed to the synchronised rupture of infected RBCs releasing merozoites and toxic haemozoin — which is also why the fever's periodicity tracks the parasite's own reproductive cycle inside blood cells.
