ASEPTIC MENINGITIS ASSOCIATED WITH ECHO VIRUS TYPE 9 INFECTION. WITH SPECIAL REFERENCE TO VARIABILITY BY SEX AND INCIDENCE OF PARALYTIC SEQUELAE

Abstract

The clinical and clinical laboratory findings in a group of 104 patients with aseptic meningitis associated with ECHO-9 infection were widely variable.A male to female case ratio of 3.7:1 was noted, and the mean age of the female group was significantly greater than that of the male group. The median of cerebrospinal fluid leukocyte counts was significantly higher in the male than in the female patients. Clinical manifestations of the disease were similar to those noted in other reports. Residual paralysis was rare and mild. Further study of the ecology of aseptic meningitis seems indicated for elucidation of the factors governing variability of the disease by sex.
