Background: Aseptic meningitis is a common disease in children; The present report describes the clinical and laboratory studies of 62 children involved in an outbreak of aseptic meningitis.
Methods: Sixty-two children with aseptic meningitis having been hospitalized from February to June 1993 were evaluated. The clinical data were obtained by review of the medical records. Initial cerebrospinal fluid (CSF) laboratory values were recorded, and CSF specimens were submitted to determine the viral etiology.
Results: Thirty-three percent of the cases were aged 2-5 years. Echovirus 30 was isolated from CSF specimens in 17 children, this is the only virus isolated from CSF during this period. The illness was characterized by transient fever, headache and vomiting. There was wide variation in the number of leukocyte from 14 to 2333 cell/mm3 in the spinal fluid. CSF protein ranged from 19 mg/dL to 114 mg/dL, and CSF sugar was normal in all specimens. Virus isolation was related to the cell count in CSF. There was no significant relationship between CSF cell count and protein content (r = 0.162, p = 0.2237). Hospital stay ranged from 1 to 14 days with an average of 3.9 days. CONCLUSIONS. The disease was mild and self-limiting without death or complication. Enterovirus isolation from CSF can substantially establish the diagnosis and the subsequent management, therefore, early discharge is expectable.
