Dengue: A focused review for the emergency clinician

Michael J Pajor et al. Am J Emerg Med. 2024 Aug.

Abstract

Dengue is an arbovirus transmitted by the Aedes spp. mosquito. Approximately 390 million infections occur annually per World Health Organization estimates, with significant increases in infections throughout the last decade. The disease is endemic in warmer climates throughout the world, though cases may also be imported to non-endemic regions by returning travelers. Patients experience a wide variety of symptoms ranging from asymptomatic infection to severe disease requiring critical care. Emergency clinicians should consider the diagnosis of dengue in patients from endemic areas presenting with a flu-like illness, rash, and evidence of bleeding.

Keywords: Dengue; Emergency department; Infectious disease; Mosquito; Returning traveler; Vector-borne disease.
