Which parasite causes malaria?

The cause of malaria is a protozoan parasite belonging to the genus Plasmodium. This group of single-celled organisms is transmitted to humans primarily through the bites of infected Anopheles mosquitoes. The life cycle of Plasmodium involves multiple stages, including an asexual phase in humans and a sexual phase in mosquitoes. The protozoan infects red blood cells and multiplies within them, leading to the symptoms commonly associated with malaria, such as fever, chills, and anemia.

Understanding that malaria is caused by a protozoan highlights the importance of targeted vector control measures and treatment strategies that specifically address these types of organisms. Other types of pathogens like fungi, viruses, or bacteria play no role in causing malaria, which makes the identification of the causative agent critical for effective prevention and management efforts.
