Malaria is a life-threatening disease caused by parasites that are transmitted to humans through the bites of infected Anopheles mosquitoes. Symptoms typically include fever, chills, and flu-like illness, and if not treated promptly, it can lead to severe complications and even death. The disease is prevalent in tropical and subtropical regions, particularly in parts of Africa, Asia, and South America. Preventive measures include the use of insecticide-treated bed nets, indoor spraying, and antimalarial medications. Efforts to control malaria focus on reducing mosquito populations and improving access to treatment.
