The Sarcoidosis is a world-wide phenomenon. The history of its epidemiological investigation is very instructive. The expectancy of noted sarcoidosis-researches that epidemiologic studies might also help to find out the cause of sarcoidosis failed. The available epidemiologic data are still confuse--the probable reasons for that has been explained. Socio-economic parameters--hitherto neglected--find increasingly consideration. The incidence is the only parameter which is suitable for reflecting the epidemiologic situation exactly. The principal problem of a reliable epidemiological research in sarcoidosis is world-wide the mode of ascertainment of the diseased persons. There is no evidence for an increase of the disease in the last 30 years.
结节病是一种全球性现象。其流行病学调查的历史很有启发性。著名结节病研究人员期望流行病学研究也有助于找出结节病的病因，但这一期望落空了。现有的流行病学数据仍然混乱——对此可能的原因已作了解释。社会经济参数——此前一直被忽视——越来越受到关注。发病率是唯一适合准确反映流行病学状况的参数。在全球范围内，结节病可靠的流行病学研究的主要问题是确定患病者的方式。没有证据表明在过去30年中该病有所增加。
