Dengue fever is a disease caused by the infection of the dengue virus to humans and is an acute febrile disease accompanied by high fever. Mosquitoes with the dengue virus spread during human bites. This mosquito is distributed in the tropical and subtropical regions of Asia, the South Pacific, Africa, and the Americas. It is a disease that does not exist in Korea, but recently, about 30 cases have been reported every year after visiting the epidemic area. Mosquitoes that transmit the dengue virus are mosquitoes that live around the house, usually in rainy lung tires or water puddles, and are mainly active during the day. When infected with the dengue virus, a sudden high fever occurs, and the fever lasts for three to five days, and severe headache, muscle pain, joint pain, and loss of appetite occur. In the early stages, red spots sometimes appear throughout the body. As the fever drops, skin rashes continue all over the body for 1 to 5 days. Initially, a millet-shaped rash temporarily appears on the face, neck, and chest, and then begins on the chest and torso on the 3rd to 4th day and spreads to the limbs and face.
