Zika Virus and Chikungunya Virus CoInfections: A Series of Three Cases from a Single Center in Ecuador. American journal of tropical medicine and hygiene Zambrano, H., Waggoner, J. J., Almeida, C., Rivera, L., Benjamin, J. Q., Pinsky, B. A. 2016; 95 (4): 894-896


Zika virus (ZIKV) and chikungunya virus (CHIKV) cocirculate throughout much of the tropical Western Hemisphere; however, few cases of coinfection with these two pathogens have been reported. Herein, we describe three cases of ZIKV-CHIKV coinfection detected at a single center in Ecuador: a patient who developed symptoms on postoperative day 5 from an orthopedic procedure, a woman who had traveled to Ecuador for fertility treatment, and a woman who was admitted for Guillain-Barré syndrome and had ZIKV and CHIKV detected in serum and cerebrospinal fluid. All cases were diagnosed using a multiplex real-time reverse transcription polymerase chain reaction, and ZIKV viremia was detected as late as 16 days after symptom onset. These cases demonstrate the varied clinical presentation of ZIKV-CHIKV coinfections as well as the importance of multiplexed arboviral testing for these pathogens.
