Dengue is an infectious disease caused by the dengue virus (DENV). There are 4 serotypes called DENV-1, DENV-2, DENV-3 and DENV-4. Infection with one serotype produces lifelong immunity against that serotype reinfection. Successive infection with two different serotypes is a risk factor for developing the severe forms of the disease.
The Aedes aegypti and Aedes albopictus mosquitoes are transmitters of dengue.
