This mosquito is a vector of malaria, and mosquito control is an effective way of reducing its incidence. Methods used to prevent malaria include medications, mosquito elimination and the prevention of bites. As of 2023, there are two malaria vaccines, approved for use in children by the WHO: RTS,S and R21.
Rhesus macaques are highly susceptible to P. knowlesi and can be infected by mosquito bite, injection of sporozoites, or injection of blood-stage parasites. [2] [10] Infected monkeys develop some hallmarks of human malaria including anemia and enlargement of the spleen and liver. [2]
Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms. Either via their bite, as in the case of malaria spread by mosquitoes, or via their faeces, as in the case of Chagas' Disease spread by Triatoma bugs or epidemic typhus spread by human body lice. Many invertebrates are responsible for transmitting diseases.
Anopheles (/ ə ˈ n ɒ f ɪ l iː z /) is a genus of mosquito first described by the German entomologist J. W. Meigen in 1818, and are known as nail mosquitoes and marsh mosquitoes. [1] Many such mosquitoes are vectors of the parasite Plasmodium , a genus of protozoans that cause malaria in birds , reptiles , and mammals , including humans.
P. malariae can infect several species of mosquito and can cause malaria in humans. [2] P. malariae can be maintained at very low infection rates among a sparse and mobile population because unlike the other Plasmodium parasites, it can remain in a human host for an extended period of time and still remain infectious to mosquitoes.

Malaria is caused by a parasite that spreads through mosquito bites. The United States has seen five cases of malaria spread by mosquitos in the last two months — the first time there's been ...
The world's deadliest animal can be squashed flat with a quick slap: It's the mosquito.. The buzzing insects are more than annoying — they spread disease. When they bite and drink blood from a ...
Mosquito-malaria theory (or sometimes mosquito theory) was a scientific theory developed in the latter half of the 19th century that solved the question of how malaria was transmitted. The theory proposed that malaria was transmitted by mosquitoes , in opposition to the centuries-old medical dogma that malaria was due to bad air, or miasma .
