Chikungunya Fever in Clinically Diagnosed Patients: A Brief Report of Comparison Between Laboratory Confirmed and Discarded Cases

摘要

Objectives: In 2015, a total of 1607 chikungunya cases were confirmed in Yucatan, Mexico, where they all took place in the second half of the year, meaning a simultaneous occurrence of both chikungunya and dengue outbreaks. This coexistence of both outbreaks posed a challenge to differentiate clinical diagnosis. The current study aimed at identifying signs and symptoms to clinically discriminate chikungunya from dengue fever in ambulatory cases.
