Dengue is a mosquito-borne viral infection or illness where a mosquito which is known as an Aedes mosquito carries the dengue virus, bites a person, and infects him/her with it. The mosquito is the carrier of the virus that carries it from an unhealthy person to a healthy person through bites and infects the blood. It does not spread through contact with the person having dengue or through touching contaminated objects as it is not a contagious disease but if the mosquito bites a person after carrying the virus from the infected one then the person can suffer from the dengue very next. Besides dengue, this infection is also known as Adan dengue, dandy, break bone fever, etc., and has symptoms such as vomiting, fever, rashes, eye pain, and many more.
