目的对河南石油勘探局新疆探区人群莱姆病进行监测,了解流行状况,为防治工作提供科学依据。方法采用间接免疫荧光抗体法(IFA)和酶联免疫吸附试验(ELISA),于1998-2003年对河南石油勘探局新疆探区人群莱姆病进行血清流行病学监测,结果统计学分析采用χ2检验。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。结果探区人群抗莱姆病螺旋体抗体(IgG和IgM)阳性率为12.07%～14.07%,平均阳性率为13.03%(1037/7956)。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%),且3组间感染率差异有显著统计学意义(χ2=101.1,P<0.01)。感染者中最小年龄6岁,最大年龄61岁,但不同年龄组感染率差异无统计学意义(χ2=7.1,P>0.01)(表2)。诊断为莱姆病者665例,患病率为8.35%。结论河南石油勘探局新疆探区人群莱姆病感染和患病率一直处于较高水平,应加强莱姆病的防治,以保护其健康。
Objective To monitor the Lyme disease in Xinjiang exploration area of Henan Petroleum Exploration Bureau to understand the epidemic situation and provide a scientific basis for prevention and treatment. Methods The indirect immunofluorescence antibody (IFA) and enzyme-linked immunosorbent assay (ELISA) were used to monitor the epidemiology of Lyme disease in Xinjiang exploration area from 1998 to 2003. The results were statistically analyzed using χ2 test. According to epidemiological data, clinical manifestations and serological test results for case diagnosis. Results The positive rate of anti-Lyme disease (IgG and IgM) was 12.07% ~ 14.07%, and the average positive rate was 13.03% (1037/7956). Among different occupational groups, the infection rate of Lyme disease was the highest (16.36%) in the field exploration and development group, the second (12.63%) in the field construction group and the lowest (7.58%) in the logistics service group, and the difference among the three groups was significant Statistical significance (χ2 = 101.1, P <0.01). The minimum age of infected persons is 6 years and the maximum age is 61 years, but there is no significant difference in infection rates among different age groups (χ2 = 7.1, P> 0.01) (Table 2). 665 cases diagnosed as Lyme disease, the prevalence was 8.35%. Conclusion The prevalence of Lyme disease and its prevalence in the Xinjiang exploration area of Henan Petroleum Exploration Bureau have been at a high level. The prevention and treatment of Lyme disease should be strengthened to protect their health.
