Concept :Malaria is a disease that affects human life. When the mosquito bites the host (human), the parasite( Plasmodium) is released into the bloodstream. They migrate to the liver and the mature parasites enter the bloodstream after several days and begin infecting RBCs.Explanation :Malaria is spread by the bite of an infected mosquito called female Anopheles.The Plasmodium parasite is carried by infected mosquitoes.The parasites spread within the RBC causing the cells infected to burst open.Plasmodiumvivax, P.ovale, P.malariae, and P. falciparum are the four kinds of malaria parasites that can infect humans.Malaria is transmitted through the skin, which means that it can also be transmitted through: 1) Transplanting an organ 2) Blood transfusionThe malarial parasite invades the body, but after a long time, it becomes dormant.Medicines used to treat Malaria are hydroxychloroquine and quinine.So, the correct answer is Female Anopheles.Additional InformationSir Ronald Ross worked on the transmission of malaria.He found that the vector of malaria i.e. the female Anopheles mosquito transmits the malarial sporozoites into the host and multiplies in the liver and moves into the salivary glands of the anopheles.Dengue fever is caused by Aedes aegypti mosquitoes.
