Abstract:

目的　中国南澎列岛恙虫病发病率近年明显增高，而国内并无该地区恙虫病疫源地的记载，为了当地军民的健康，本研究对该地区作为恙虫病疫源地进行全面调查与研究。方法　疫源地流行病学调查、病原分离、当地预防措施的制定。结果　该地区为南亚热带岛屿疫源地，主要宿主为褐家鼠，主要媒介为地里纤恙螨。褐家鼠与地里纤恙螨的季节消长与发病均一致。从宿主与媒介分离到恙虫病立克次体经鉴定为Karp株。血清流行病学调查表明该岛临时居民恙虫病抗体100.0%阳性，部队人群阳性率达4.0%。本研究确立了中国南澎列岛恙虫病疫源地的存在，同时制作了卫生宣教录像片、编写了恙虫病防护手册与流行前期的卫生课，对该地区军民进行卫生宣教提高防病意识，流行季节前对该疫源地进行大面积灭鼠、灭螨措施，对人员进行个体防护。综合措施应用后当年无病例发生。结论　中国南澎列岛是恙虫病疫源地。

Objective To investigate the region fo r the epidemic area of tsutsug amushi disease. Methods　Epidemiological studies, Orientia tsutsug amushi isolation, and preventive measures were used. Results　The region belonged to epidemic area of south subtropical zone.The main host was found Rattus norvegicu.The main biological vector was Leptotrombidium deliens.The seaso nal trends of the quantity of Rattus no rveg icu and Leptotrombidium deliens w ere consistent with the incidence change of the disease in the region.Orientia tsutsug amushi has been isolated from Rattus norvegicu and Leptotrombidium deliens. Data showed that Orientia tsutsugamushi isolated strains mainly belong s to Karp.Sero-epidemiological data show ed that antibodies of Orientia tsutsugamushi are 100.0% positive in the residents of the regio n and 4.0% in army men.After taking comprehensive preventive measures, the incidence was descending.
