在没有系统接种卡介苗和环境分枝杆菌感染频率低的低患病率国家，应对每一个确认的结核病病例或结核分枝杆菌感染进行源检测。有时这种搜寻会导致发现一种微流行病。如果将观察到的群体流行率与预期的群体流行率进行比较，就可以很容易地确定微流行中接触者筛查的程度。所描述的方法说明了在源情况周围的同心圆中寻找接触点的方法：池中石头原理。
In a low prevalence country with no systematic BCG vaccination and a low frequency of environmental mycobacterial infections, for each recognized case of tuberculosis or infection with M. tuberculosis source detection should be undertaken.Sometimes this search will lead to the discovery of a microepidemic. The extent of contact screening in a microepidemic can easily be determined if observed group prevalences are compared to expected group prevalences. The described method illustrates this search for contacts in concentric circles around the source case: the stone-in-the-pond principle.
