Coefficient of variation (CV) values allowed the categorization of the perception of future and current risk in two classes based on a cut-off of 4 (< 4 and ≥ 4) that described the main trend for the different situations and different arboviral diseases. Generally (dots in grey color), the coefficients of variation (CV) values were higher for values lower than 4 (corrected CV = range values between 36.160 and 93.415, p < 0.001) than for values higher or equal to 4 (corrected CV = range values between 22.004 and 50.095, p < 0.001). Conversely, for the imported cases of dengue nation-wide (in red color), the variation coefficients were identical in both groups (corrected CV = 43.553 and 44.420, respectively, p = 0.995).
