Association of clinical presentation, laboratory findings, and virus serotypes with the presence of meningitis in hospitalized infants with enterovirus infection.
One hundred eight hospitalized infants with enteroviral infections were studied to determine the association of clinical presentation, laboratory findings, and virus serotypes with the presence of meningitis. Of 108 infants, 55 (51%) had meningitis. Clinical manifestations on admission did not distinguish between infants with and those without meningitis. Echoviruses 30 and 11 and coxsackie virus B were frequently associated with meningitis (34/38; 90%) whereas echoviruses 18, 24, and 25 were not (5/35; 4%). The virus isolation rate was directly proportional to the number of leukocytes in cerebrospinal fluid: 5 of 58 (9%) when up to 9 cells/mm3 were found, 10 of 21 (48%) when 10 to 99/mm3 cells were found, and 25 of 29 (86%) when greater than equal to 100 cells/mm3 were found. Meningitis is often unsuspected in children hospitalized with enterovirus infection. The frequency of meningitis among hospitalized infants is serotype dependent and is most frequently, but not exclusively, found with pleocytosis of the cerebrospinal fluid.
