肺结核病人是肺结核的主要传染源,因此如何能有效地把肺结核病人发现出来,加以治疗和管理,使之消失传染性不再成为传染源,是控制结核病的最重要也是最有效的环节。这里必须强调,发现病人仅是一种手段,其目的是为了治愈病人不再成为传染源,因此发现病人自始至终应当和治疗管理紧密结合。如果发现了病人不加治疗或治疗不当,那么在流行病学及控制结核病工作中都是有害而无益的。发现病人的方法和手段肺结核是一种慢性传染病,它持续不断地在人群中发生和流行,因此发现病人必须是一项经常性的工作。它不同于流行病学调查中发现病人的工作。因为后者是一项有时间限制的 Tuberculosis patients are the main source of TB infection. Therefore, how to effectively find out TB patients for treatment and management so that they disappear. Infection is no longer a source of infection and is the most important and effective link in controlling tuberculosis. It must be emphasized here that the discovery of the patient is only a means of curing the patient from becoming a source of infection and therefore finding that the patient should be closely integrated with the management of the treatment. If the patient is found to be untreated or ill-treated, it is both detrimental and beneficial in the epidemiology and control of tuberculosis. Methods and Means to Discover Patient Tuberculosis is a chronic infectious disease that continues to occur and prevail in the human population and therefore found that patients must be a regular job. It differs from the patient’s job found in epidemiological surveys. Because the latter is a time limit
