Explanation - Dengue is a vector-borne disease transmitted by the bite of an infected female Aedes Aegypti mosquito. The mosquito becomes infected when it feeds on the blood of a person infected with the virus. After about one week, the mosquito can then transmit the virus while biting a healthy person. There are 4 serotypes of the virus that causes dengue. These are known as DEN-1, DEN-2, DEN-3, DEN-4. Type II and IV are considered to be more severe and may require hospitalisation. Infection with one strain will provide life-time protection only against that particular strain. However, it is still possible to become infected by other strains and develop into severe dengue. Dengue cannot be spread directly from person to person. However, a person infected and suffering from dengue fever can infect other mosquitoes. There is no vaccine or specific medication for dengue fever. Patients should seek medical advice, rest and drink plenty of fluids.
