Plasmodium is a genus of single-celled parasites known for causing malaria, a serious disease transmitted through the bites of infected Anopheles mosquitoes. There are several species of Plasmodium, with Plasmodium falciparum being the most dangerous. These parasites enter the human bloodstream, where they multiply and invade red blood cells, leading to symptoms like fever, chills, and fatigue. The life cycle of Plasmodium is complex, involving both humans and mosquitoes. After a mosquito bites an infected person, it ingests the parasites, which then develop in the mosquito before being transmitted to another human. Understanding this cycle is crucial for controlling malaria and reducing its impact on public health.
