Abstract

Several outbreaks of epidemic encephalitis have occurred in the United States in recent years. The most severe epidemic was in St. Louis in the summer of 1933. Smaller outbreaks were reported in Paris, Ill., Kansas City, Kan., and St. Joseph, Mo. We wish to report observations made during an epidemic which occurred in Toledo, Ohio, during the summer of 1934. It is our purpose to demonstrate that the disease which occurred in Toledo is epidemiologically, clinically and pathologic-anatomically identical with the St. Louis type of encephalitis and the Japanese type of encephalitis (encephalitis B of Kaneko and Aoki1) and is not identical with lethargic encephalitis (Economo's disease). Of the fifty cases that occurred in Toledo (tables 1 and 2), clinical and pathologic examination was possible in two.
