Change from baseline WBC counts following challenge of CMs with CHIKV. WBC counts of CMs challenged by ID inoculation (top graph) or by aerosol (bottom graph) were determined on days 2, 4, 6, 8, and 13 post-challenge. Mean changes from baseline WBC counts are shown with standard normal 95% confidence intervals for each group. * - group mean WBC count significantly decreased compared to baseline at 0.05 level; # - group mean WBC count significantly increased compared to baseline at 0.05 level; numbers in parentheses represent the number of groups significantly different from baseline at that time point
