目的探讨部队某部新兵连一起结核病聚集的流行因素,控制结核的进一步蔓延。方法对该部所有新兵及密切接触者进行流行病学调查、X线检查、结核菌素试验、X线检查异常者进行痰结核菌检查,查找结核菌,确诊结核病人,追踪传染源。结果 2008年2月-2009年2月1年内,640名新兵中共确诊活动性结核34例,罹患率5.31%。时间分布呈现两个小高峰,在春秋季。PPD检测人数扩大到新兵密切接触者,共833例,阳性共598例,结核感染率71.79%;强阳性48例,强阳性率5.76%。大大高于对照的未发病部队(P<0.01)。结论首发病例的误诊和未隔离是本次暴发的源头。应加强上下级卫生防疫部门的沟通,采取综合性的结核病防治措施,预防结核病的聚集流行。
Objective To explore the prevalence of tuberculosis in a recruits unit and to control the further spread of tuberculosis. Methods All recruits and close contacts of the department were investigated for epidemiological investigation, X-ray examination, tuberculin test and X-ray examination to find tuberculosis of sputum, to find out the TB bacterium, to confirm the tuberculosis patients and to track the source of infection. Results From February 2008 to February 2009, a total of 640 newly recruited Chinese confirmed the diagnosis of active tuberculosis in 34 cases, with an attack rate of 5.31%. Time distribution presents two small peaks in spring and autumn. The number of PPD detection increased to close contact with recruits, a total of 833 cases, a total of 598 cases of positive, tuberculosis infection rate was 71.79%; strong positive in 48 cases, strong positive rate of 5.76%. Significantly higher than the control of unaffiliated troops (P <0.01). Conclusions Misdiagnosis and non-isolation of the first case are the source of this outbreak. The departments of health and epidemic prevention at the lower and middle levels should strengthen their communication and adopt comprehensive anti-tuberculosis prevention and control measures to prevent the epidemic of tuberculosis.
