济南东郊秋冬型恙虫病临床流行病学研究

Studies on Clinical Epidemiology of Tsutsugamushi Disease of the Autumn winter Type in the Easten Suburbs of Jinan

作者对济南东郊１５４例恙虫病做临床流行病学研究。结果表明，济南东郊恙虫病临床特点与南方恙虫病不尽相同，以全身中毒症状为主，典型特征不明显，焦痂或溃疡仅占１４．９４％，而且多见于秋冬季；临床病例以轻型为主，不仅合并器官损害多，而且呈散在分布，患者以青壮年农民占多数；恙虫病立克次体（Ｒｔ）为弱毒株，流行血清型Ｇｉｌｉａｍ型。

This paper reported the epidemiological characteristics of 154 cases under investigation for tsutsugamushi disease of autumn winter type in the eastern suburb of Jinan. Results showed that the characteristics differed greatly from those in the southern part of China. Majority of patients had toxic symptoms due to infections but specific characteristics were less obvious. Eschars and ulcers appeared only in 14.94% of the cases and occurred only in autumn winter season. Clinically mild cases constituted the majority. Cases not only distributed sporadically,but also had multi organ lesions (MOL). Young peasants seemed to be most vulnerable. The pathogen of the disease belonged to low virulent strain. Serological typing belonged to the Gilliam type. The diagnosis and the treatment of the disease were discussed. Specific serum IgG of the disease was detected 6 years after convalescence.
