Clinical, virological, and antibody profiles of overlapping dengue and chikungunya virus infections in children from southern Colombia

The pediatric population in southern Colombia was rapidly exposed to CHIKV infections during the first months following its arrival, with up to 12% of hospitalized children suspected of having dengue experiencing CHIKV monoinfection, supporting that complex and dynamic epidemiological patterns may lead to delayed or missed diagnoses. The overlapping infections of DENV and CHIKV were frequent and did not lead to worse clinical or fatal outcomes.
