The epidemiology of meningococcal disease in Europe since 1945 has shown fluctuations in incidence, serogroup distribution and case-fatality rate. Outbreaks and epidemics driven by the introduction of new virulent strains into Europe have occurred unpredictably. Epidemics associated with serogroups A and B have occurred in all regions of the continent. Additionally, there have been periods of increased outbreak frequency, such as those associated with serogroup C in the 1980s and 1990s, against an endemic disease incidence of around one to two cases per 100,000 population. Serogroup W135 disease was observed in the 1970s and again in 2000, while serogroup Y has recently emerged in Sweden and the Czech Republic. This article describes the changing epidemiology of meningococcal disease in Europe. An understanding of this is important for informed decision-making about different meningococcal vaccines that may be considered for use in Europe.
