Figure 4. Older Ifnar1−/− mice remain susceptible to ZIKV infection.

Figure 4

3, 4, or 6 month-old Ifnar1−/− C57BL/6 mice were infected with 103 FFU of ZIKV (H/PF/2013) by a subcutaneous route. A. Mice were weighed over 21 days with data censored at 9 days after infection, when mice began to succumb. Weights are expressed as a percentage of starting weight, shown as the mean ± SEM of 5 mice per group. B. Survival was monitored for 21 days.
