目的分析梧州市大中专新生结素试验(PPD试验)强阳性人群的特征,为制定大中专学校结核病防控措施与方案提供科学依据。方法对梧州市2010-2015年大中专新生进行PPD试验,一年后对强阳性者(排除当年确诊结核者)进行X胸片复查,同时在“结核病管理信息系统”上监测有无发病,并对结果进行统计分析。结果新生PPD试验强阳性率为3.51%,各年强阳性率差异无统计学意义(χ2=8.308,P>0.05),发病率为22.57/10万。未在监测的强阳性学生中发现肺结核病例,近6年来梧州市大中专学校未发生结核病聚集性疫情。结论大中专学校的结核病防治工作任重道远,要采取综合干预措施,建立学校结核病预警,对重点学生群加强监测至关重要。
Objective To analyze the characteristics of strong positive population of freshmen in Wuzhou college and junior high school (PPD test), and to provide a scientific basis for the development of prevention and control measures and programs for tuberculosis in colleges and technical secondary schools. Methods The PPD test was conducted in freshmen of Wuchuan from 2010 to 2015. One year later, the X-ray examination of strongly positive persons (except the ones diagnosed with tuberculosis in those years) was carried out. At the same time, the “Tuberculosis Management Information System” was used to monitor the presence of Morbidity, and statistical analysis of the results. Results The positive rate of newborn PPD test was 3.51%. There was no significant difference between the two groups in the positive rate of PPD (χ2 = 8.308, P> 0.05). The incidence rate was 22.57 / 100000. Tuberculosis cases were not detected in the strong positive students monitored. In the past 6 years, there was no tuberculosis epidemic in Wuzhou colleges. Conclusion There is still a long way to go to TB prevention and control work in colleges and technical secondary schools. Comprehensive interventions should be taken to establish early warning of tuberculosis in schools and it is crucial to strengthen the monitoring of key student groups.
