IFNAR−/− mice inoculated with CCHFV Hoti develop an inflammatory immune response to the infection. IFNAR−/− mice were inoculated with 1 TCID50 of CCHFV strain Hoti. At the indicated time points, serum was collected and irradiated, and cytokine levels were quantified with a 23-plex mouse cytokine kit. Statistical comparison to mock-infected mice was performed using an ordinary one-way ANOVA with the Holm-Sidak multiple-comparison test. *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001. n = 5 to 8 per group. Horizontal bars indicate the mean.
