Dengue | Dengue Fever: Symptoms, Causes, and Treatments

Dengue is a viral infection caused by the dengue virus (DENV), transmitted to humans through the bite of infected mosquitoes.
About half of the world's population is now at risk of dengue with an estimated 100-400 million infections occurring each year.
Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas.
While many DENV infections are asymptomatic or produce only mild illness, DENV can occasionally cause more severe cases, and even death.
Prevention and control of dengue depend on vector control. There is no specific treatment for dengue/severe dengue, and early detection and access to proper medical care greatly lower fatality rates of severe dengue.
