1952—2007年内蒙古自治区布鲁杆菌病疫情分析

Epidemic situation analysis of human brucellosis in Inner Mongolia during 1952 to 2007

目的分析内蒙古自治区布鲁杆菌病疫情，探讨不同时期影响疫情的可能因素，为制订内蒙古自治区当前布鲁杆菌病防治对策提供依据。方法收集1952—2007年内蒙古自治区布鲁杆菌病监测数据和已发表文献中相关数据，对布鲁杆菌病在不同时期、不同人群、不同地区分布情况进行描述性统计分析。结果1952—2007年间内蒙古自治区出现2次布鲁杆菌病流行高峰，20世纪50年代末60年代初出现第1次发病高峰，范围波及全区12盟（市），其中1961年发病率最高，达55．28／10万；病例职业构成中牧民最高，占72．9％；2000年后出现第2次发病高峰，其中2005年发病率最高，达38．44／10万，以中、东部地区最为严重；病例职业构成中以农民和牧民为主，分别占51．9％和28．7％。结论随着畜牧养殖业的快速发展，牲畜交易频繁，使得内蒙古自治区布鲁杆菌病疫情从90年代中期开始快速上升，2004—2007年达流行高峰。

Objective To explore the possible factors associated with twice human brucellosis epidemics in Inner Mongolia during 1952 to 2007 to provide scientific tactics for prevention and control brucellosis. Methods Surveillance data and literature about human brucellosis during 1952 to 2007 in Inner Mongolia was collected, descriptive analysis of human brucellosis incidence on distribution in the regions and among occupations was carried out during 1952 to 2007. Results In Inner Mongolia, the first epidemic of human brucellosis peak appeared in the early 1960s, spreading to 12 regions, at an incidence of 55.25/100 000 in 1961, 72.9% of the Brucella infected people were herdsman; another epidemic peak seriously hit middle and eastern regions after 2000, the incidence being 38.44/100 000 in 2005; 51.9% and 28.7% of the new brucellosis cases were respectively peasant and herdsman. Conclusions In Inner Mongolia, animal husbandry industry has been rapid developed since the early 1990＇s, resulting frequent livestock trade without quarantine, at the same time the public health system doesn＇t match the development, so the epidemic situation of brucellosis becomes more and more serious after mid90＇s, and has reached the peak during 2004 and 2007.
