There occurred an explosive outbreak of aseptic meningitis in Ulsan, in the year of 2002. In this study, we report clinical manifestations, laboratory data and causative viruses of the outbreak. METHODS: Were assessed 371 children with aseptic meningitis who were admitted to the Department of Pediatrics, Ulsan University Hospital in Ulsan between May and July, 2002. We reviewed the sex, age, clinical manifestations, peripheral blood examinations and CSF examinations of the patients. Virus isolation and serotype identification were performed by cell cultures of cerebrospinal fluid and stool. RESULTS: The ratio of males to females was 1.9:1. The majority of aseptic meningitis occurred in children between 1 and 5 years of age with a mean age of 6.8+/-5.1 years. The clinical manifestations was fever, headache, vomiting, and abdominal pain and 16.2% of the patients developed neck stiffness. The mean duration of fever was 3.2 days. The mean value of peripheral blood leukocytes was 10,355+/-4,800/mm3 and the mean value of CRP was 0.96+/-1.67 mg/dL. Initial CSF findings revealed leukocytes 212+/-385/mm3, protein 37.0+/-18.9 mg/dL and glucose 68.3+/-17.6 mg/dL. Viruses were isolated 67(18.1%) out of 371 patients and the serotypes were echovirus 6 in 10 cases, echovirus 9 in 15 cases, echovirus 11 in 4 cases, echovirus 13 in 18 cases, and unclassified enterovirus in 20 cases. CONCLUSION: Aseptic meningitis was prevalent in Ulsan, in the year of 2002. The clinical manifestations and the laboratory findings of the patients were compatible with those of previous reports. The causative viruses were echovirus 6, echovirus 9, echovirus 11, echovirus 13 and unclassified enterovirus.
