Definition of Dengue fever:

Dengue fever is a virus-based disease spread by mosquitoes.

Causes, incidence, and 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

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.
