目的了解长沙市人间布鲁氏菌病(布病)的感染情况,为布病疫情的防控提供科学依据。方法按照WS269-2007《布鲁氏菌病诊断标准》对2012—2015年长沙市布病疑似病例和接触人群,同时进行虎红平板凝集试验(RBPT)和试管凝集试验(SAT)血清学检测,用描述流行病学方法进行分析。结果 2012—2015年长沙市布病SAT阳性率32.34%(76/235),2015年最高为77.14%(χ2=46.573,P<0.001),男女阳性率分别为34.84%和27.50%,差异无统计学意义(χ2=1.299 P=0.254),各年龄组阳性率差异有统计学意义(χ2=25.334,P<0.001),50岁~组最高(52.56%),不同职业阳性率差异有统计学意义(χ2=25.334,P<0.001),以饲养放牧人群阳性率最高(44.59%),RBPT和SAT两种方法检测结果差异无统计学意义(P>0.05)。结论长沙市人间布病疫情有上升的趋势,早期血清学检测能有效的对疾病进行诊断,应该加强重点人群的血清学监测工作,加强布病防控知识的健康教育,减少布病的发生。
Objective To understand the prevalence of brucellosis (brucellosis) in Changsha and provide a scientific basis for the prevention and control of brucellosis. Methods According to WS269-2007 Diagnostic Criteria of Brucellosis, the serological tests of RBPT and SAT were carried out in the suspected cases of Clostridium brucellosis and contact with people in Changsha from 2012 to 2015, Describe the epidemiological method for analysis. Results The prevalence of brucellosis in Changsha was 32.34% (76/235) in 2012-2015, the highest was 77.14% in 2015 (χ2 = 46.573, P <0.001). The positive rates of male and female were 34.84% and 27.50% respectively, with no statistical difference (Χ2 = 1.299 P = 0.254), the positive rate of each age group was statistically significant (χ2 = 25.334, P <0.001), the highest age group of 50 years (52.56%), the positive rate of different occupations was statistically significant (χ2 = 25.334, P <0.001). The highest positive rate was found in rearing herd (44.59%). There was no significant difference between RBPT and SAT (P> 0.05). Conclusion The prevalence of brucellosis in Changsha City is on the rise. Early serological tests can effectively diagnose the disease. Serological surveillance of key populations should be strengthened to improve the health education of prevention and control of brucellosis and reduce the incidence of brucellosis.
