Education and information regarding malaria and the biology of the disease including life cycle, mosquitoes, parasites and human factors.
The life cycle of the falciparum malaria parasite is complex when an infectious mosquito feeds on a human being, parasites (called sporozoites) are injected. These human cell populations are all necessary to complete the life cycle of plasmodium falciparum, the most virulent species causing malaria mice with. Malaria is caused by the protozoan parasite plasmodium the parasite has a life-cycle of 24 h and can give rise to daily fever spikes occurring 9–12 days after .
