Number of positive human serum samples in the hemagglutination inhibition assay (titer >40) for each test virus compared with the total number of samples tested per birth cohort. Birth cohorts are represented as different colors. During August 2017–January 2018, a total of 549 serum samples were collected from immunocompetent persons in Belgium.
