ENTEROVIRAL SYNDROMES IN TORONTO, 1964.

Abstract

Virological or serological investigations of 72 children in Toronto and environs, who were hospitalized between January and October 1964 with a variety of syndromes, revealed evidence of enteroviral infection in 29 subjects. Coxsackie B2 was the dominant enterovirus, being isolated from feces and/or cerebrospinal fluid (CSF) of three children with aseptic meningitis, three with pleurodynia, one with myalgia and one with pericarditis; four additional patients showed rising antibody titres to this virus. Coxsackie B1 virus, which has not been isolated in Toronto since 1950, was recovered from feces of three patients with pleurodynia, CSF of one patient with myalgia, and peritoneal fluid of a child with primary peritonitis; one patient with pericarditis showed a rising antibody titre to Coxsackie B1 virus. Coxsackie B3, B4 and Echo 23 viruses were associated with one case each of pleurodynia. Coxsackie B5 virus infected five patients with aseptic meningitis, and one each with pericarditis and myocarditis.
