目的对高校两起肺结核疫情暴发及其潜伏期进行分析探讨,为早期诊断、早期治疗肺结核,防止暴发肺结核疫情提供可借鉴经验。方法对研究对象进行PPD试验检测、胸部X线检查并进行流行病学资料调查分析,并对结果进行探讨。结果结核病人现多无临床症状;两起疫情传染源的密切接触者都是在短期内感染发病,且早期可为潜伏感染,2~4周发病。结论对学校这一特殊群体,应警惕较短的潜伏期内结核感染集中发病;且有必要反复跟踪检查,以避免肺结核在校园内暴发流行。 Objective To analyze and analyze the outbreak of two tuberculosis outbreaks in universities and to provide experience for early diagnosis, early treatment of tuberculosis and prevention of outbreak of tuberculosis. Methods The subjects were tested by PPD test, chest X-ray examination and epidemiological data investigation and analysis, and the results were discussed. Results There was no clinical symptom in TB patients. The close contacts of both epidemic sources were all infected in a short time, and could be latent infection in the early stage, with onset of 2 ~ 4 weeks. Conclusions For this special group in school, we should guard against the concentration of TB infection in a short incubation period. It is also necessary to follow up and check repeatedly to avoid the outbreak of tuberculosis on campus.
