  "summary": "Circular RNAs (circRNAs) are covalently closed RNA molecules with regulatory functions. Although virus-derived circRNAs (vcircRNAs) are well characterized in DNA viruses, their occurrence in RNA viruses remains poorly understood. Recent reports in coronaviruses and hepatitis C virus suggest that vcircRNA production extends beyond nuclear-replicating viruses. Here, we show that Zika virus (ZIKV),…",
