    Snippet: Ribavirin is a well-known nucleotide analog and its anti-flavivirus activity has previously been reported [20, 35] . Ribavirin showed moderate anti-ZIKV activity in our assay (EC 50 value of 45.5 ± 13.5 µM and EC 90 value of 114.5 ± 18.0 µM), consistent with previous reports displaying a variable efficacy range of ribavirin against ZIKV (EC 50 between 20 and 48 µM) [37] [38] [39] .

    Document: Ribavirin is a well-known nucleotide analog and its anti-flavivirus activity has previously been reported [20, 35] . Ribavirin showed moderate anti-ZIKV activity in our assay (EC 50 value of 45.5 ± 13.5 µM and EC 90 value of 114.5 ± 18.0 µM), consistent with previous reports displaying a variable efficacy range of ribavirin against ZIKV (EC 50 between 20 and 48 µM) [37] [38] [39] . Favipiravir failed to display anti-ZIKV activity in our assay. Lei Cai et al. have showed an EC 50 value above 100 µM (EC 50 was 110.9 ± 13.1 µM) for favipiravir, which was the highest compound concentration in our assay [40] . Thus, antiviral activity might have been observed with increased concentration of favipiravir.
