Malaria is an infectious disease caused by several species of parasites transmitted by mosquitoes. About 2 million deaths per year occur due to malaria, the majority of them being children. The largest numbers of deaths and infections occur in sub-Saharan African countries.
Malaria signs and symptoms: After the initial mosquito bite, the incubation period is usually about one to three weeks but may range from a few days to about one year in some individuals. The initial symptoms are flu-like with fever, chills, muscle aches, and headaches. A cough, nausea, vomiting, and diarrhea could develop and within a few days, cycles of chills (shaking chills), fever, and sweating episodes that repeat every one, two, or three days is typical for malaria patients.
