目的分析锦州市1999-2013年布鲁氏菌病疫情流行病学特征,为今后制定防控策略提供参考依据。方法对布病疫情流行病学特征进行描述性分析,利用SPSS17.0对试管凝集试验阳性率与发病率之间进行Pearson相关性分析。结果 1999-2013年锦州市布病发病率在0.13/10万-12.04/10万之间。凌海市病例数最多,占45.37%。发病的时间主要集中在3-6月,共2 262例,占62.48%。发病人群男女性别比为3.03:1。采集重点人群血清4 861份,其中SAT阳性221份,阳性率4.54%。101份血培养标本中分离出布氏菌46株,其中羊种3型33株、羊种1型10株,羊种变异2株、犬种1株。结论锦州市布病发病率每3~4年出现一个自然流行周期,优势菌株主要是羊种3型。
Objective To analyze the epidemiological characteristics of brucellosis in Jinzhou City from 1999 to 2013 and provide reference for future prevention and control strategies. Methods The epidemiological characteristics of brucellosis were analyzed descriptively. Pearson correlation analysis was used to analyze the positive rate and incidence of coagulation test by SPSS17.0. Results The incidence of brucellosis in Jinzhou between 1999 and 2013 ranged from 0.13 / 100,000 to 12.04 / 100,000. Linghai City, the largest number of cases, accounting for 45.37%.
