目的 分析甘肃省2009和2010年人间布鲁杆菌病（布病）疫情流行特点及规律，为布病防制提供依据。方法 利用“中国疾病预防控制信息系统”数据库以及人间布病爆发调查资料，分别计算2009和2010年甘肃省布病发病率以及新发病例构成，慢性期布病构成，分析病例的三间分布。结果 2009和2010年布病发病率分别为0.37/10万和0.17/10万，新发病例占报告病例总数的54.6％(83/152)和51.8％(43/83)；慢性期病例分别达到53.3％(81/152)和56.6％ (47/83)。甘肃省86个县（市、区）约1/3有疫情，病例集中在河西走廊和陇东一带，有3个县发生爆发疫情。5、7、9、12月为发病高峰期，呈锯齿状，9月最高。病例男女性别之比为3:1,平均年龄46岁，67.7％(159/235)为农民，其次为离退人员以及牧民，各约占7％。结论 甘肃省人间布病疫情呈迅速上升趋势，全年均有发病，受累人群主要为男性青壮年农民，布病慢性化比例高。今后应加大防治力度，提高布病防护意识。

Analysis of surveillance results on human brucellosis in 2009 and 2010 in Gansu province

Objective Through analyzing the epidemic characteristics and laws of human brucellosis in Gansu province during the past two years,to provide the basis for control of the disease. Methods Using "China Information System for Diseases Control and Prevention V2.0" and survey data of human brucellosis outbreak,we calculated the incidence of brucellosis and the composition of new cases and chronic cases in 2009 and 2010, respectively, and analyzed the three distributions of the disease. Results Brucellosis incidence was 0.37 per million in 2009, and 1.7 per million in 2010. The new cases accounted for 54.6％(83/152) and 51.8％(43/83),and chronic cases were 53.3％ (81/152) and 56.6％ (47/83), respectively. About 1/3 of the counties (cities,districts) was found to be with the disease, and most cases were clustered in Hexi Corridor and Longdong area of Gansu province. There were three counties with outbreak. Time distribution of the disease was jagged. May, July,September and December were high, with September the highest. Sex ratio was 3 : 1, and mean age was 46 years old.67.7％ (159/235) of cases were farmers, followed by retired officers and herders, with a percentage of about 7％,respectively. Conclusions Epidemic of human brucellosis shows a rapidly rising trend in Gansu province. There are new patients throughout the year, and young farmers are the main victims. A high proportion of chronic brucellosis is more harmful. Strengthen the prevention and control of the disease to increase their brucellosis protective awareness.
