How is malaria transmitted


The main way that malaria is spread is by the bites of female Anopheles mosquitoes carrying Plasmodium parasite infections. These mosquitoes have the ability to carry and spread the parasites from one person to another, making them disease vectors. The parasite’s sporozoites are injected into the circulation when an infected mosquito bites a human. The sporozoites then proceed to the liver, where they develop and proliferate inside of liver cells.

The parasites develop in the liver for a while before being discharged back into the circulation and invading red blood cells. The parasites develop and proliferate inside the red blood cells until the cells finally rupture. This sequence of red blood cell invasion, proliferation, and burst results in the typical malarial symptoms, including fever, chills, headache, and exhaustion.

It’s crucial to remember that not every type of mosquito may spread malaria. The parasites that cause malaria can only be transmitted by female Anopheles mosquitoes. In areas where malaria is endemic, sleeping under insecticide-treated bed nets is an essential preventive precaution because these mosquitoes usually bite at night or in the early morning.

Although mosquitoes are the main carrier of malaria, the illness can also spread through organ transplants, blood transfusions, and pregnancy-related transmission from mother to fetus (congenital malaria). In contrast to mosquito-borne transmission, these mechanisms of transmission are less frequent.

The main goal of efforts to stop the spread of malaria is to lower the number of mosquitoes that carry the disease by using vector control techniques like insecticide-treated bed nets, indoor residual pesticide spraying, and environmental management to remove mosquito breeding grounds. Key tactics for stopping the spread of malaria also include early detection and treatment of infected patients as well as chemoprevention with antimalarial drugs.


 The main way that malaria is spread is by the bites of Anopheles mosquitoes carrying the infection, which injects malaria parasites into the bloodstream during feeding. To effectively prevent and manage malaria and lessen its global impact on impacted populations, it is imperative to comprehend the mechanics of malaria transmission.
