ECHO VIRUS TYPE I AND ASEPTIC MENINGITIS. REPORT OF A CASE WITH VIRUS ISOLATION FROM THE CEREBROSPINAL FLUID.

ECHO virus, type I was isolated from the cerebrospinal fluid and feces of an infant with aseptic meningitis. A fourfold rise in neutralizing antibody to the prototype virus occurred. This virus has been recovered from sick and well individuals but its isolation from cerebrospinal fluid has not been reported previously in the English literature. The patient subsequently appeared retarded but other possible responsible factors were present. Our findings contribute to the evidence that ECHO Type I may be etiologically related to aseptic meningitis.
