Is Malaria Transmitted by Female Mosquitoes?

August 20, 2012 By Malaria Q&A Leave a Comment

QUESTION Is malaria caused by only female mosquitoes? ANSWER Malaria is only transmitted by female mosquitoes, yes. This is because only female mosquitoes of the genus Anopheles (the genus that transmits malaria in mammals, including humans) feed on blood, and the parasite that causes malaria (called Plasmodium) spends part of its life cycle in the blood. Therefore, when a female mosquito … [Read more...]

Structure and Size of Malaria Mosquito

QUESTION Which are malaria hosts and how does malaria have an effect on one of them? ANSWER The parasite which causes malaria (called Plasmodium) requires two different hosts—a vertebrate intermediate host, such as a human, and an insect definitive host, also known as the vector. For the types of malaria which infect humans and other mammals, the vector is always a mosquito of the … [Read more...]

Causes of Malaria

June 5, 2012 By Malaria Q&A Leave a Comment

QUESTION What are the causes of malaria? ANSWER Malaria is caused by a parasite called Plasmodium, which is transmitted via the bites of infected mosquitoes. In the human body, the parasites multiply in the liver, and then infect red blood cells. Usually, people get malaria by being bitten by an infective female Anopheles mosquito.  Only Anopheles mosquitoes can transmit malaria and … [Read more...]

Is Malaria a Mosquito STD?

May 27, 2012 By Malaria Q&A Leave a Comment

QUESTION Is Malaria a type of STD for mosquitoes? ANSWER No. Mosquitoes pick up the malaria parasite from feeding on the blood of infected humans. Since only female mosquitoes feed on blood (the males feed on nectar), male mosquitoes never get infected with the malaria parasite. The life cycle of malaria in the mosquito is also completely different than in humans, and mosquitoes have a … [Read more...]

Life Cycle of Malaria

May 22, 2012 By Malaria Q&A Leave a Comment

QUESTION Why does the malaria parasite first enter the liver? ANSWER The malaria parasite enters the liver in order to transform from a sporozoite (which can infect liver cells) to a merozoite, which is capable of infecting red blood cells. Both stages also include a proliferation step, but in the blood, the merozoites are also able to differentiate into gametocytes, which are then taken … [Read more...]

Anopheles Mosquito

May 1, 2012 By Malaria Q&A 4 Comments

QUESTION Why is it only the female anopheles mosquito alone can cause malaria but not the male anopheles mosquito or any other mosquitoes? ANSWER Malaria is actually caused by a single-celled parasite called Plasmodium—it is transmitted via the bite of a female mosquito, of the genus Anopheles, as she takes a blood meal from a human (or other mammal) host. Male mosquitoes do not … [Read more...]
