What is malaria


Through the bites of female Anopheles mosquitoes carrying the parasite that causes malaria, people can contract this dangerous and frequently fatal illness. Plasmodium parasites are the cause of the disease, with Plasmodium falciparum being the most lethal species. Malaria continues to pose a serious threat to international health, especially in tropical and subtropical areas where the Anopheles mosquito is most prevalent.

When an infected mosquito bites a human and injects sporozoites into the bloodstream, the malaria parasite’s life cycle starts. After arriving in the liver, these sporozoites develop and proliferate inside the cells of the liver. Depending on the species of Plasmodium, the parasites are released back into the bloodstream where they infect red blood cells after a few days or weeks. The parasites inside the red blood cells keep growing, which leads to the cells rupturing open and releasing more parasites into the circulation. The distinctive symptoms of malaria are caused by this cycle of red blood cell invasion, growth, and rupture.

Malaria usually manifests as fever, chills, headache, aches in the muscles, and exhaustion. Serious cases of malaria can result in organ failure, convulsions, coma, and even death. This is especially true if the illness is managed poorly or if receiving the right medical care and diagnosis takes longer than expected. Pregnant women and small children are among the groups most susceptible to severe malaria.

The use of insecticide-treated bed nets to lessen mosquito bites, indoor residual spraying to eliminate mosquitoes, and chemoprevention with antimalarial medications in endemic areas are some preventive strategies against malaria. Reducing the disease’s associated mortality and morbidity requires prompt and efficient antimalarial medicine treatment.

The global burden of malaria has been reduced through measures including vector control, better diagnoses, and treatment accessibility over the decades-long efforts to manage and eradicate the illness. There are still issues, though, such as medicine resistance, financing shortages, and how climate change is affecting mosquito habitats.


Malaria is a disease that can be prevented and treated, but it still presents a serious threat to public health in many regions of the world. In order to eradicate malaria worldwide and lessen its devastating impact on vulnerable populations, there must be sustained investment in research, preventative tactics, and healthcare infrastructure.
