Answer
The primary vector responsible for the transmission of malaria is the Anopheles mosquito. This genus of mosquitoes are the carriers of the Plasmodium parasites. When an infected Anopheles mosquito bites a human, the parasites enter the bloodstream, leading to malaria infection. This method of transmission is crucial in the life cycle of the Plasmodium parasite.

Answer
Malaria is not transmitted through direct human contact. It requires a vector, specifically the Anopheles mosquito, to carry the parasite from one host to another.

Answer
The transmission of malaria does not occur through particles in the air. It requires the bite of an infected mosquito, making airborne transmission irrelevant in this context.

Answer
Plasmodium falciparum is the parasite that causes the most severe form of malaria; however, it is transmitted by the Anopheles mosquito. Thus, while it plays a crucial role in the disease, it is not a mode of transmission by itself.
