An outbreak of viral central nervous system infection occurred from May to September, 1991 in Shanghai, China. Totally 376 cases were admitted into our hospital, 54% with encephalitis and 46% with meningoencephalitis. Echovirus type 30 was isolated from CSF and stools of the patients. Only 3 of the patients were under 1 year of age. CSF examination revealed the cell count from 0-1600 x 10(6)/L. Interestingly, 9 had CSF PMNs over 90% and 13 had low sugar levels. EKG was randomly done in 20 patients and 15 demonstrated myocarditis. The outcome was uneventful in all except 1 who had psychological problem at the time of discharge.
