我国恙虫病(Scrub typhus)主要流行于江南诸省,八十年代以来,南方老疫区连续发现新的传播媒介,北方新的疫区不断被发现,恙虫病不仅流行于北纬30°以南地区,1986年山东、江苏首次发现恙虫病流行,并从病人血液、黑线姬鼠、小盾纤恙螨分离出恙虫病立克次体。由于新疫区,新媒介诸方面的发现,本病的研究工作取得了很大进展,现就近几年来流行病学方面的进展简述如下。地区分布目前我国恙虫病的地区分布还缺乏全面调查,根据现有资料分析,主要流行于长江以南的东南和西南地区的台湾、福建、广东、广西、云南、西藏、浙江等省区。八十 Scrub typhus is endemic in Jiangnan provinces. Since the 1980s, new vectors have been continuously found in the endemic areas in southern China. New epidemic-prone areas in northern China have been continuously discovered. Scrub typhus is not only endemic to the area south of 30 ° N In 1986, Shandong Province and Jiangsu Province first discovered the epidemic of scrub typhus and isolated Rickettsia tsutsugamushi from the blood of patients, Apodemus agrarius, and chigger mite. Due to the discovery of new epidemic areas and new media, great progress has been made in the research of this disease. The progress of epidemiology in recent years is summarized as follows. Regional distribution At present, there is still a lack of comprehensive survey on the distribution of scrub typhus in our country. According to the analysis of available data, it is mainly popularized in Taiwan, Fujian, Guangdong, Guangxi, Yunnan, Tibet and Zhejiang provinces in the southeast and southwest of the Yangtze River. eighty
