With 40% of the world's population living in areas at risk for transmission, dengue virus infection is a leading cause of illness in the tropics and subtropics.

Although dengue rarely occurs in the continental United States, it is endemic in most US Territories such as Puerto Rico and the US Virgin Islands. Dengue is endemic in essentially all tropical and subtropical tourist destinations, worldwide (see map at right). The public health problem is that dengue incidence is increasing worldwide, and the severity of disease appears to be worsening.

Dengue is a reportable condition in the United States as of 2010. All confirmed and presumptive cases of dengue should be reported to local and state health departments.
