Transition in the cause of fever from malaria to dengue, Northwestern Ecuador, 1990-2011

Abstract

In tropical areas, the predominant cause of fever has historically been malaria. However by 2011, among febrile patients in northwestern Ecuador, dengue was identified in 42% and malaria in none. This finding suggests a transition in the cause of fever from malaria to other illnesses, such as dengue.

Keywords: ELISA; Ecuador; dengue fever; dengue virus; etiology; febrile; malaria; reemergence; reverse transcription PCR; surveillance; vector-borne infections; viruses.
