Malaria is a parasitic disease transmitted through mosquito bites. It causes high fevers, shaking chills, and flu-like symptoms. The parasites travel to the liver and infect red blood cells, causing symptoms like anemia. Diagnosis involves examining blood smears under a microscope to detect the parasites. Treatment depends on factors like location and severity, but most cases only require medication prescribed by a doctor. Prevention involves eliminating mosquito breeding sites and using nets, repellents, clothing coverage and anti-malarial drugs.
