In the prevalence of Japanease B Encephalitis in Okayama and Kagawa Prefecture in 1956, the number of the patients increased with a sudden drop in temperature by typhoon No. 9.
In the past, the Japanease B Encephalitis spreaded in order to Kagawa Prefecture→south Okayama Prefecture→north Okayama Prefecture. While in the prevalence of 1956, this tendency could not be demonstrated, the epidemie occurred simultaneously. The two strains “Okayama 56 E” “Okayama 56 F” were isolated from the brain of the patients respectively, and this both strains were serologically identified with “Japanease B Encephalitis Nakayama strain”.
