Mumps and enteroviral meningitis in Toronto, 1966.
Of 52 children admitted to hospital for apparently typical mumps meningitis in 1966, 50 had their cerebrospinal fluid (CSF) examined. In only 17 was the mumps virus isolated from the CSF. Mumps antihemagglutinin conversions or increments were detected in 32 subjects including 10 whose CSF yielded virus. Antibody conversions were found in 16 patients and fourfold increments in another nine whose serum pairs were collected only one to four days apart. Initial sera from 20 patients were obtained three days or less after the onset of meningitis. Antibody increments were frequently noted about one day after defervescence and clinical improvement. Interferon was detected in CSF from two of eight patients, both of whom yielded virus. Enteroviruses were isolated from CSF and/or feces in seven of 15 cases of aseptic meningitis which occurred between July and October. Six patients including three virus excretors showed enteroviral neutralizing antibody increments during convalescence. The dominant enteroviral serotype was coxsackievirus A9.
