The highest incidence (more than 3/100,000) of meningococcal serogroup C meningitis was found in Ireland, Iceland, Malta, the United Kingdom, Denmark, the Netherlands, Scotland and Spain. One possible explanation could be the emergence of a new clone of group C infection that has spread through England and Wales, as well as some areas of Europe.
Countries of average incidence (1-3/100,000) include Belgium, Norway, Slovak Republic, Switzerland, Lithuania, Ukraine, Spain, Portugal, Austria, Czech Republic, Greece, Latvia and the European part of Russia.
Low incidence (less than 1/100,000) has been reported from Croatia, Finland, France, Sweden and other European countries. In Germany the incidence of meningococcal C infections seems to be stable over the recent years (79% of cases caused by type B, 21% by type C). The case fatality rate of the disease is about 10%. Careful surveillance of the epidemiology of meningococcal disease in Germany is mandatory.
According to data collected in 1999, the overall incidence in Europe is 1.8/100,000 inhabitants.
