Dengue fever is a quite dangerous febrile disease that can even cause death. Nowadays, this disease can be found in the tropics and Africa. Do not think that it is only thick forests where dengue fever can be found. The urban areas of many developed countries like Brazil, Singapore, Taiwan, Indonesia, and India are also vulnerable to this disease. Dengue fever is transmitted by the Aedes aegypti mosquito, which also transmits such diseases as Chikungunya and yellow fever.
