  1. Overview showing results for all four sampled herds, including the number of individuals of different tick species collected, CCHFV-positive ticks (Pos.), and analysis of the correlation between the three identified species and CCHFV status by χ2-test (p < 0.05)
  2. CI Confidence interval, NA not available (due to the absence of H. impeltatum at the sampling site)
