为了揭露生产場所气象条件在生产工人咽峡炎的病因学中所起的作用与意义,作者分析了列宁格勒工人的咽峡炎发病率:1925—1950年期间计480,000例,1951—1955年计291,000例。分析结果表明:发病率有着按年度的周期性的波动。发病率水平升高持续几年,接着下降,以后又复有几年升高。这种波动主要是由于人群免疫力变动的结果,不作详述。
To reveal the role and significance of meteorological conditions in production sites in the etiology of angina in production workers, the authors analyzed the incidence of angina in Leningrad workers: 480,000 cases between 1925 and 1950, 1951-1955 291,000 cases were counted. The results of the analysis show that the incidence is cyclically fluctuating on an annual basis. The incidence rate increased for several years, then declined, and then increased again in recent years. Such fluctuations are mainly the result of changes in the population’s immunity and will not be described in detail.
