2007—2013年秦皇岛市卢龙县人间布鲁菌病流行情况

Epidemic of human brucellosis in Lulong County of Qinhuangdao from 2007-2013

目的了解秦皇岛市疾病预防控制中心在卢龙县监测点人间布鲁菌病(以下简称布病)流行规律及地区分布情况,为政府制定防治策略提供科学依据。方法根据GB 16885-1997《布鲁氏菌病监测标准》及《全国人间布鲁氏菌病监测方案》,对卢龙县2007—2013年人间布病监测检验结果进行分析。结果 7年间卢龙县12个乡镇共检测采集血清标本1 762份,检出阳性126份,阳性率为7.15%;其中主动检验362人,阳性67例,阳性率18.50%;抽样监测检验1 400人,阳性59例,阳性率4.21%。职业人群以饲养员感染率最高,为12.12%(79/652),不同职业发病率差异有统计学意义(P<0.01);男女阳性率分别为8.13%、4.03%,差异有统计学意义(P<0.01)。不同年龄组阳性率差异无统计学意义;不同地区间人间布病监测检验阳性率差异无统计学意义,其中蛤泊乡最高,为11.67%(23/197)。结论卢龙县人间布病疫情2007—2010年逐年上升,近几年有下降趋势,主要与近几年防治力度加大有关,应加强传染源的管理控制,继续加强人间布病监测,深入开展对重点人群进行宣传教育和行为干预。

[ Objective ] To understand the epidemic law and regional distribution of human brucellosis in Lulong County of Qin- huangdao, provide basis for formulating the preventive and control measures.

[ Results] 1 762 serum specimen were collected in 12 villages of Lulong County in 7 years. 126 samples were positive, the positive rate was 7.15%. There were 362 examination volunteers, among which the posi- tive rate was 18.5% with 67 positive samples; there were 1 400 random supervision samples, among which the positive rate was 4. 21% with 59 positive samples. The infection rate of breeder was the highest with 12.12% （79/652） , the difference of the inci- dence among different career groups was statistically significant （ P 〈 0.01 ）. The positive rates of male and female were 8.13% and 4.03%, and the difference was statistically significant （ P 〈 0.01 ）. The difference of the positive rate among different age groups was not statistically significant （ P 〈 0.01 ）. The difference of the positive rate among different regions was not statistically significant （P 〈 0.01）, among Habo Village was the highest with 11.67% （23/197）. [ Conclusion ] The epidemic situation of hu- man brucellosis in Lulong from 2007-2010 rises year by year, but there is a downturn in recent years because of the stronger force of the disease prevention and control.
