Dengue fever is a dangerous vector-borne disease that is widespread in regions with subtropical and tropical climates. Aedes aegypti mosquitoes are the main carriers of the disease. Without carriers, the disease doesn't pose an epidemiological threat. Symptoms of dengue include a high fever, nausea, dizziness, headache and lumbar pain. The hemorrhagic variant of the fever is followed by severe internal bleeding caused by collapse of blood vessels. According to the World Health Organization, the mortality rate from the severe form of the disease is 2.5% and can reach 20% without proper treatment.
