目的通过T-SPOT.TB试验检测了解人群聚集场所人员结核分枝杆菌潜伏性感染状况。方法对人群聚集场所人员组(122名)、结核病相关医护技人员组(64名)和涂阳肺结核组(22名)共208名受检对象分别进行T-SPOT.TB试验,了解结核分枝杆菌潜伏感染状况。结果 208名受检人员中,结核潜伏感染人群90人,总潜伏感染率43.27%。人群聚集场所人员潜伏感染率57.38%(70/122);医护技人员潜伏感染率31.25%(20/64);涂阳肺结核患者阳性率100%(22/22)。结论人群聚集场所人员结核潜伏感染率高,应加强防控措施。
Objective To detect the latent infection of Mycobacterium tuberculosis in the crowded places by T-SPOT.TB test. Methods T-SPOT.TB test was performed on 208 subjects in the crowd gathering place (122), tuberculosis related medical technicians (64) and smear-positive pulmonary tuberculosis (22) Bacillus latent infection. Results Of the 208 subjects examined, 90 were latent tuberculosis infection, with a total latent infection rate of 43.27%. The prevalence of latent infection in people gathering places was 57.38% (70/122), the latent infection rate of medical technicians was 31.25% (20/64), and the positive rate of smear-positive pulmonary tuberculosis was 100% (22/22). Conclusion There is a high latent infection rate of tuberculosis among people in crowded places, and prevention and control measures should be strengthened.
