Framework to Detect Emerging Infectious Diseases

Dengue is a viral disease transmitted by the bite of an Aedes mosquito. The infection causes a flu-like illness that occasionally develops into a life threatening condition known as severe dengue. Dengue is mainly found in tropical and sub-tropical climates worldwide, and the US typically only sees cases imported from travelers who became infected while visiting areas where dengue commonly exists. However, in recent years, outbreaks have occurred within the US where residents had no travel history indicating that transmission is occurring locally.

State and local public health laboratories diagnose suspected dengue cases through virus isolation, serological tests or molecular methods. In order to support public health laboratories, APHL and CDC are developing dengue testing guidance documents to build a framework to detect dengue in the US.
