Malaria is a disease caused by a plasmodium parasite, which can be transmitted through the bite of an infected mosquito. The signs and symptoms of malaria include fever with rigorous chills, sweating, headaches, and fatigue, which usually occur with a few weeks of a mosquito bite. If you want to travel to areas where malaria is endemic, you must take prophylaxis drugs before, during and after the trip. Hydroxychloroquine and chloroquine are the most commonly used drugs to prevent as well as treat malaria.
