The life cycle of the malaria parasite Plasmodium falciparum is a complex one involving the mosquito and the human. The definitive host for this infection is the mosquito and the intermediate host is the human. Asexual reproduction occurs during the infection of humans but sexual reproduction occurs in the mosquito. The infection is transmitted through the bite of the Anopheles mosquito, which is prevalent in tropical areas. Climate change means that mosquitoes are becoming more widespread, but developed countries are better equipped to control them.
