[A study on the incidences of streptococcal infectious diseases in the regional surveillance informations of infectious diseases in Japan (2nd report)].
The incidences of streptococcal infectious diseases in the regional surveillance informations of infectious diseases of 47 prefectures were compared with each other by the ratios of number of patients with streptococcal infectious diseases, exanthema subitum and varicella to the populations of surveyed age groups, respectively. It was estimated that although there were almost no regional differences in the ratios of exanthema subitum and varicella, the ratios of streptococcal infectious diseases were high in Hokkaido, Akita, Yamanashi, Shiga and Ehime Prefectures, respectively, and was low in Okinawa Prefecture. The corrected incidences of number of patients with streptococcal infectious diseases, calculated on the basis of the ratios of exanthema subitum and/or varicella, were also high in the regions of Hokkaido, Akita, Iwate, Nagano, Yamanashi, Gifu, Shiga, Okayama and Ehime Prefectures, respectively, and were low in the regions along the Pacific from the southern Tohoku (northern Japan) through a part of the Shikoku Island and the Sea of Japan from the Hokuriku (central Japan) through the Kyushu Island, and the regions of Nara and Okinawa Prefectures, respectively. The climate in the regions with high corrected incidence belonged to the Tohoku-Hokkaido, the Central Highlands and the Seto Inland Sea types, respectively. On the other hand, the regions with low corrected incidence belonged to the Tokai-Kanto, the Nankai (southern sea of Japan), the Hokuriku-Sanin, the Kyushu and the Okinawa climate types, respectively.
