An Influenza epidemic in Kyushu and Yamaguchi Prefectures occurred the months of January to March of 1964. This epidemic was unusual in that it was prevalent only in Kyushu and Yamaguchi profectures, contrary to past epidemics which have generally spread, in time over all the districts of Japan. This fact seemed to indicate that the present epidemic was due to a new type of influenza virus and (or) to a specific immunological state in these districts.The present study was designed to determine the type and character of this particular virus, and to clarify the degree to which it spread in the course of the epidemic. Therefore, epidemiologic examinations were carried out on the isolated virus and on es imating the situation of antibody retention before and after the epidemic.
