Malaria - Definition
Malaria is a serious, infectious disease spread by certain kinds of mosquitoes. It is common in tropical climates and is characterized by chills, fevers, and an enlarged spleen. These symptoms reappear again and again. The disease can be treated with medication, but it tends to come back even after being cured. Malaria is endemic in many developing countries. An endemic disease is one that occurs frequently in a particular location. Isolated, limited outbreaks of malaria sometimes occur in the United States.
