Incidence of invasive meningococcal disease caused by serogroups B, C, W and Y, by age group for individual countries and Europe, 2017 (n = 2,859)

BEL: Belgium; CZE: Czechia; DEU: Germany; DNK: Denmark; ESP: Spain; FIN: Finland; FRA: France; GBR: UK; IMD: invasive meningococcal disease; IRL: Ireland; ITA: Italy; LTU: Lithuania; NLD: the Netherlands; NOR: Norway; PRT: Portugal; SWE: Sweden.

Data are for individual countries (black circles) and Europe (26 countries included; red diamonds). The number of IMD cases in Europe is indicated in red for each age group. Boxes indicate 25th, 50th and 75th percentiles of incidence rates for each group; whiskers indicate lowest and highest data point excluding any outliers. An incidence of 0 in specific age groups is likely to be related to the population sizes of the individual countries.
