2005-2006年深圳市布鲁氏菌病监测点监测结果分析

Analysis on the Brucellosis Surveillance in Shenzhen City from 2005 to 2006

目的对深圳市2005-2006年布鲁氏菌病(布病)疫情进行监测,掌握布病疫情动态,为制定防制对策提供依据。方法按全国布病监测方案要求,对全市监测点内7～60岁人群进行连续监测。结果2005-2006年在监测点内(均在宝安区公明监测点)共检出布病16例(其中新发感染10人),血清学监测阳性率为1.96%。2006年(3.2%)检查阳性率高于2005年(1.05%);两年血清学调查的815人中,配种员的感染率最高,为7.69%(1/13),其次为饲养员4.44%(15/338),其他职业未发现阳性;男性血清学阳性率为2.39%,女性阳性率为1.11%,性别阳性率无统计学意义(!2=1.52,P=0.22);对血清学检测中试管凝集1:500以上者5人份血清样本经广东省疾病预防控制中心病原分离,未分离出布鲁氏菌。结论深圳市布病监测点内疫情有上升趋势,职业人群中以青壮年为主,布病牛是我市人间布病的主要传染源,因此及时发现、处理布病牛是控制布病发生流行的关键措施。

Objective To analyze characteristics of brucellosis epidemic through 2005 to 2006 for the purpose of providing effective prevention and control strategies and measures for the disease in concern. Method According to the national surveillance protocol, populations aged 7 to 60 in the sentinel sites of surveillance were surveyed consecutively. Result In total during 2005 to 2006, 16 cases were found（including 10 new cases）, generating a serological positive rate of 1.96%. Statistic analysis proved that positive rate of 2006 （3.2%）out of 815 surveyed was higher than that of 2005（1.05%, x^2=4.95, P=0.03）. Hybridization persons had the highest infection rate （1/13, 7.69）, followed by breeding persons （15/338, 4.44%）. Other occupations were all negative. Positive rate for males （2.39%） and females （1.11%） were not statistically significant （x^2=1.52, P=0.22）. Guangdong Provincial CDC cultivated 5 samples with tube agglutination test （SAT） results of found higher than 1：500, but no bacterium was found. Conclusion There is an uprising trend of brucellosis epidemic in Shenzhen in the past two years, age group of 20-50 is at the highest risk, cows with brucellosis is the main infection sources in Shenzhen, and key control measures should be put on detecting and sacrificing the sick animals timely.
