The data on the application of the principles of the self regulation of the epidemic process for understanding the annual dynamics of angina morbidity in organized groups of adults are presented. In this case the reservation of group A streptococci occurs in chronic (resident) carriers, whose proportion was found to be 15.8 +/- 2.6%. The epidemic manifestations of morbidity are regulated mainly by the concentration of newly arrived members in the groups, i. e. by the size of the stratum providing the optimum conditions for the parasitization of the streptococcal population. The annual morbidity levels depend essentially not only on the heterogeneity of the group members with respect to their susceptibility to streptococcal infection, but also on the conditions of their accommodation, affecting the transmission of droplet infection. The role of individual risk factors in the variation of the quantitative characteristics of the angina morbidity manifestations under study is calculated.
本文展示了运用流行过程自我调节原理来理解成年人群体中心绞痛发病率年度动态变化的数据。在这种情况下，A组链球菌在慢性（常住）携带者中存在，其比例为15.8±2.6%。发病率的流行表现主要受群体中新加入成员的数量调节，即受为链球菌群体寄生提供最佳条件的阶层规模调节。年度发病率水平不仅基本上取决于群体成员对链球菌感染易感性的异质性，还取决于他们的居住条件，这些条件影响飞沫感染的传播。计算了个体风险因素在所研究的心绞痛发病率表现定量特征变化中的作用。
