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.
