[A study on the examination of the incidences of streptococcal infectious diseases in the nationwide and the regional surveillance information of infectious diseases in Japan (1st report)].
As the first step to examine the incidences of streptococcal infectious diseases for the nationwide and the regional surveillance information of infectious diseases in Japan, the number of patients with streptococcal infectious diseases per year or week and the hospitals in the surveillance systems in 47 prefectures from 1982 to 1987 were compared. It was found to have the tendency that the numbers of the patients were comparatively more in Hokkaido, Tohoku, partial areas of Kyushu and Shikoku than in other regions, and more in rural areas than in urban areas. Because of the deviation from the tendency, however, it was also suggested that the information of the disease in some prefectures might be poor. Although ratios of no. of the patients against no. of patients with exanthema subitum in 16 prefectures, respectively, were calculated and compared, it was be not enough to analyze the difference among the incidences of streptococcal infectious diseases in these prefectures.
