WITH the purpose of determining whether or not there occurs any deficiency in nerve function after the acute stage of Japanese B encephalitis had been passed safely, 19 persons were studied who had had the disease within the preceding forty-five to sixty days. The patients were adult Americans confined to the 361st Station Hospital in Tokyo. In addition, 12 Japanese patients with late effects, over half of them children, were surveyed at the Komagome Hospital, in Tokyo. The disease had been proved serologically in both the American and the Japanese group. The Japanese remained in the hospital because of the severity and the crippling nature of their residual defects; the Americans, because the military services wanted to make certain that their patients had made the maximum recovery.

In addition to the epidemic of 1948, large outbreaks of Japanese B encephalitis had been recorded in Japan in 1871, 1924 and 1935.
