Dengue fever is a virus-based disease spread by mosquitoes.
See also: Dengue hemorrhagic fever
Overview, Causes, & Risk Factors
Dengue fever is caused by one of four different but related viruses. It is spread by the bite of mosquitoes, most commonly the mosquito Aedes aegypti, which is found in tropic and subtropic regions. This includes parts of:
- Indonesian archipelago into northeastern Australia
- South and Central America
- Southeast Asia
- Sub-Saharan Africa
Dengue fever is being seen more in world travelers.
Dengue fever should not be confused with Dengue hemorrhagic fever, which is a separate disease that is caused by the same type of virus but has much more severe symptoms.
