The clinical features and long-term sequelae of invasive meningococcal disease in children.

We evaluated the outcome of invasive meningococcal disease in children <15 years of age (n = 181). Neisseria meningitidis serogroup B comprised 78% of bacterial isolates. Case fatality rate was 11.6%. In follow-up interviews (115/160 survivors, 72%), at least 1 long-term sequela was reported in 38/115 children (33%), including learning-academic difficulties (22.6%), hearing impairment (7%), neurologic (12.2%), behavioral (14.8%) and motor (10.4%) deficits.
