摘要: 目的 查明河南油田所属新疆石油探区人群莱姆病感染与发病情况,为防治工作提供科学依据。方法 采用普查方法进行流行病学调查,间接免疫荧光抗体法(IFAT)和酶联免疫吸附试验(ELISA)进行血清抗莱姆病螺旋体抗体检测。根据流行病学资料、临床表现和血清学检查结果 进行病例诊断。统计学分析采用χ2检验。结果分别进行了5次调查,共计7956人,检测到抗莱姆病螺旋体抗体(IgG/IgM)阳性者1037份,感染率为12.07%~14.07%,平均感染率为13.03%。不同职业人群中,莱姆病感染率以野外勘探开发组最高(16.36%),野外建设施工组次之(12.63%),后勤服务组最低(7.58%),3组间感染率差异有统计学意义(χ2=101.1,P<0.01)。感染者中年龄最小6岁,最大61岁,但不同年龄组感染率差异无统计学意义(χ2=7.1,P>0.1)。诊断为莱姆病者665例,患病率为8.36%。结论 河南油田新疆石油探区人群存在莱姆病感染,并有莱姆病的发生和流行,应加强莱姆病的防治,以保护其健康。

Abstract: Objective To investigate the Lyme Borreliosis status of infection of population in Xinjiang Prospecting Bureau of Henan oilfield to provide scientific basis for Lyme disease prevention and cure. Methods With census method epidemiological investigations were carried out in the crowd. All serum samples were detected by IFAT and ELISA for antibodies (IgG/IgM) against Borrelia burgdorferi. Cases of Lyme disease were made a definite diagnosis by epidemiology,clinical symptoms and serological results. The results were analyzed with χ>2 test. Results Total 7 956 people were investigated in five times of which 1 037 people had a significant antibody titer,the average positive rate was 13.03% ( 12.07%-14.07% ). Among different professional populations,the positive rate in the wild prospecting population was the highest ( 16.36% ),in the wild constructing population was the second ( 12.63% ),and in the service population was the lowest ( 7.58% ),in which there were significant difference (χ2=101.1,P<0.01). The youngest infected with Lyme spirochete was 6 years old and the oldest was 61,but there were no significant difference in age groups (χ2=7.1,P>0.1). 665 cases with Lyme disease were confirmed,the prevalence rate was 8.36% . Conclusion The results showed that the population of Xinjiang Prospecting Bureau of Henan oilfield were infected with Lyme borreliosis,and in which Lyme disease has occurred. So the prevention and treatment must be enhanced.
