帯状疱疹および熱帯性疾患

GEOGRAPHIC DISTRIBUTION OF HERPES ZOSTER AND TROPICAL DERMATOSES

I．帯状疱疹

第1図は西日本地区における帯状疱疹の分布状態の色分けの規準を示したもので，人口10万対の患者数を横軸にとり，各々に該当する地域数を縦軸下にとり，これらの地域数の高さが大体似かよつたものを1群として大ざつぱに区切つた各群に属する地域数の総数を縦軸上に示したものであるが，ただ患者数50以上では分布も極めて疎らになるので，区切のよいように50から100迄と100以上とに分けた。すなわち：

　第1群は患者数が「0」及至1.9迄の地域で，「0」地域が49,1.9迄の地域が5，総計54地区である。

1. Distributitn pattern of the incidence of herpes zoster in the southern part of Japan : It is higher in Kyushu than Chugoku district, especially in the cities on the coast in the western part of the Kyushu Mountains. In Chugoku it had higher incidence in Yamaguchi prefecture and in some parts of Hiroshima prefecture, especially in the cities on the coast of the Seto-naikai.

In general, its occurrence is lower in the mountainous area of inland than in the coastal area. Some borderline area between the prefectures had extremely low frequence of herpes zoster.

2. Geographic distribution of filariasis in southern part of Japan : The order of its frequ-ency was in Kumamoto and then in Nagasaki prefecture. It is higher in southern part of the Kyushu Mountains. It is not rare in the cities on the coast of the Setonaikai.

Its sporadic occurrence was observed in other prefectures than above mentioned ones except Hiroshima and Tokushima prefecture.

Because most of the patients with filariasis consulted urologist, this statistical analysis was not perfect. In this report Shimane, Ehime, Kagawa and Kochi prefecture were omitted because their informations were not sufficient for statistic studies.
