Malaria is a serious infection. It is common in tropical countries such as parts of Africa, Asia and South America. Malaria is a disease caused by a parasite called Plasmodium that lives in mosquitoes.
Malaria is caused by a bite from a mosquito infected with parasites. In very rare cases, people can get malaria if they come into contact with infected blood. You cannot get malaria just by being near a person who has the disease. What are the symptoms? Most malaria infections cause symptoms like the flu, such as a high fever, chills, and muscle pain. Symptoms tend to come and go in cycles. Some types of malaria may cause more serious problems, such as damage to the heart, lungs, kidneys, or brain. These types can be deadly.
