Yellow fever is an extremely rare infection spread by a particular species of mosquito called the aedes aegypti, and it is endemic in areas of Africa and South America. The “yellow” in yellow fever alludes to the jaundice of the eyes and skin that transpire in some patients. Some of the most typical symptoms include fever, headache, nausea, and vomiting. In Africa, a small proportion of the people who contract a severe case of the virus die within 7 to 10 days. The number of cases has been on a rise since 1980. An approximate 200,000 cases happen each year. Of that large amount, about 30,000 die. Malaria is a rare disease caused by parasites and transferred by the bite of an anopheles mosquito that is carrying the infection.
