The clinical features of paediatric meningococcal disease Auckland, 1985-87

An epidemic of group A meningococcal disease began in Auckland in May 1985. There were 122 paediatric cases of meningococcal disease in the next 25 months including 98 cases due to group A. The commonest clinical symptoms were vomiting, headache and photophobia, while frequent signs included fever, seizures, petechial rash and meningism or a bulging fontanelle. Complications were uncommon and included sterile arthritis and prolonged fever. The majority had disease confirmed by positive blood or cerebrospinal fluid culture. Significantly fewer positive cultures were seen in those treated with antibiotics prior to admission. The overall mortality was 7%. If the acute illness was survived, the only detected long term sequela was sensorineural hearing loss seen in 6%. A vaccine programme has been undertaken to control this epidemic.
