IgM and IgG responses in a cross-sectional survey: A Antibody levels. Box-plots represent the median and the interquartile range; error bars indicate the 5–95 percentiles; filled symbols represent outliers. Differences in the antibody levels between the age groups were analyzed with Kruskal-Wallis test with Dunn’s multiple-comparison test. B Seropositive rates. Bars represent the proportions of IgM and IgG seropositive individuals in the different age groups. The seropositive cut off values (mean + 2SD) for antibody types were: IgM 8.82 × 10− 3 and IgG 9.32 × 10− 4. Error bars indicate 95 % confidence intervals. Differences between the groups were analyzed with Fisher’s exact test. ****p < 0.0001, ***p < 0.001, **p < 0.01, *p < 0.05
