Seroprevalence of tick-borne encephalitis virus (TBEV) in patients and healthy donors according to gender, type settlement, and age. (a) Comparison of total prevalence values between the studied groups. (b) Comparison between the groups of males, and also between females from patients and healthy donors. (c) The patients and donors were also compared when inhabiting in urban, or from rural areas. (d). Comparisons were performed in each age group as well, despite the no children or seniors individuals were present in the cohort of healthy donors. RR: relative risk, indicate the probability of an individual in the groups of “Patients” to be seropositive to TBEV. RR = ∞ (undefined) when the prevalence value equals 0 in a group. The significance of the association was also tested by Fisher exact test (* p < 0.05; ** p < 0.01; ns, non-significant).
