CDC recently released a new guide, Response to Dengue Cases in Non-Endemic Areas of the United States, to assist state, tribal, local, and territorial health departments in areas where dengue is not endemic to investigate and respond to importation and potential transmission of dengue virus (DENV). This includes algorithms to guide the investigation of suspected dengue cases, DENV transmission risk levels and recommended actions for travel associated dengue cases, and recommended actions for locally acquired dengue cases. This document provides guidance on how to use the algorithms and additional considerations when implementing recommended actions. CDC is available to support jurisdictions and health care providers with any inquiries, consultations, or assistance with investigations by contacting the Dengue Branch at dengue@cdc.gov.
CDC has also compiled Public Health Considerations for Dengue for responding to travel-associated or locally acquired dengue cases in areas where the disease does not occur frequently.
