Meningitis in an Irish community.

A series of 26 cases of meningitis occurring in one year in a defined area is presented. The clinical features, and complications are reviewed. Neisseria meningitidis occurred twice as commonly as Haemophilus influenzae, suggesting that the pattern of infection differs from that reported in England and Wales. An incidence of 4.6/100,000 for N. meningitidis is reported exceeding rates of infection in previous UK "epidemics".
