Estimated posterior distributions of the susceptibility to infection of 5-14y (A), 15-64y (B) and 65 + y (C) age group (mean and 95%CI) relative to the 0–4 years age group (for which the susceptibility to infection is set to the reference value of 1). Only types/subtypes that accounted for more than 15% of the positive samples are considered. The values reported above the vertical lines in the right panels represent the 97.5% percentile of the distribution, when the value exceed the limit of the vertical axis
