Age-dependent viremia in Florida cotton rats inoculated subcutaneously with 3 log10 PFU of subtype IE Venezuelan equine encephalitis virus. Randomly picked female and male animals aged 3–8 weeks were inoculated subcutaneously with 3 log10 PFU. Significant differences were detected on day 2 postinoculation (*p = 0.007) and day 3 (**p = 0.02) but not on day 1 (***p = 0.06). Bars indicate standard errors of the means.
