Concurrent Dengue-Malaria Infection: The Importance of Acute Febrile Illness in Endemic Zones.

Context: Acute febrile disease (AFI) in endemic tropical areas is a frequent reason for consulting the emergency services. Infection by 2 or more etiological agents may modify clinical and laboratory parameters, making diagnosis and treatment a challenge.

Case Report: We report the case of a patient who came from Africa and consults in Colombia, with AFI with thrombocytopenia that was eventually diagnosed to have concurrent infection with malaria and dengue.
