Detailed explanation-1: -Malaria is transmitted to humans by female mosquitoes of the genus Anopheles. Female mosquitoes take blood meals for egg production, and these blood meals are the link between the human and the mosquito hosts in the parasite life cycle.
Detailed explanation-2: -Infective stage of Plasmodium to human beings is sporozoite and it is formed in gut of female Anopheles mosquito.
Detailed explanation-3: -Malaria is caused by a single-celled parasite of the genus plasmodium. The parasite is transmitted to humans most commonly through mosquito bites.
Detailed explanation-4: -Malaria is caused by a single-cell parasite called Plasmodium. The parasite infects female mosquitoes when they feed on the blood of an infected person. Once in the mosquito’s midgut, the parasites multiply and migrate to the salivary glands, ready to infect a new person when the mosquito next bites.
