Meningococcal meningitis is an acute bacterial infectious disease with severe sequelae and high mortality. The morbidity of this disease is low in Taiwan and most cases were sporadic. One junior high school student was reported in March, 2008 and later confirmed. In retrospective investigation and follow-up monitoring, another 4 cases were confirmed. Pulsed-field gel electrophoresis examination also revealed identical genotyping of bacterial strains isolated from these patients. This was a rare cluster outbreak of meningococcal meningitis occurred at school campus in recent years in Taiwan.
Two runs of mass chemoprophylaxis had been administered in school for disease control. This report discussed the effectiveness and adverse drug reaction of prophylaxis of this disease. Furthermore, crowding environment may be an important factor in this outbreak and, thus, environmental improvement was proceeding in this school to prevent further infection of meningococcal meningitis or other respiratory diseases.
