The average morbidity level in scarlet fever for the period of 1972-1990 in Moscow was 230.9 cases per 100,000 of the population and the annual economic damage was 2-2.5 million rubles. The highest morbidity rate values were registered among children attending children's institutions, and in this group among children aged 3-6 years. Cohort and disperse analysis revealed that age-dependent fluctuations of morbidity rate had a regular character and significantly differed. An increase in scarlet fever morbidity was registered simultaneously with elevated levels of morbidity in tonsillitis and acute respiratory diseases and occurred several weeks after a rise in tonsillitis morbidity. Contamination with group A streptococci was higher among "organized" children of preschool age than among other groups of the population. T serovars 4/28, 8/29/Imp.19, 3/13/B3254 and 1, constituting 44% of all isolated Streptococcus pyogenes strains, and OF type 2 (44%) and 22 (20%) occurred most frequently. Among the strains isolated from patients T-4 and OF-2 types prevailed.
1972年至1990年期间，莫斯科猩红热的平均发病率为每10万人230.9例，每年的经济损失为200万至250万卢布。发病率最高的值出现在就读于儿童机构的儿童中，且在该群体中3至6岁的儿童发病率最高。队列分析和离散分析显示，发病率的年龄依赖性波动具有规律性且差异显著。猩红热发病率的上升与扁桃体炎和急性呼吸道疾病发病率的升高同时出现，且在扁桃体炎发病率上升几周后发生。学龄前“集体生活”儿童中A组链球菌的感染率高于其他人群组。T血清型4/28、8/29/Imp.19、3/13/B3254和1型，占所有分离出的化脓性链球菌菌株的44%，其中OF型2（44%）和22（20%）最为常见。在从患者分离出的菌株中，T-4型和OF-2型占主导。
