Neisseria meningitidis Infections in Northern Norway: An Epidemic in 1974-1975 Due Mainly to Group B Organisms
A severe epidemic of disease due to Neisseria meningitidis has been occurring in northern Norway since 1974. Based on bacteriological and clinical examination of cases during the 18 months between January 1, 1974 and June 30, 1975, an overall attack rate of 26.3 cases per 100,000 population per year...
