The work deals with the results of typhoid morbidity in Moscow for the period of 1980-1988. The morbidity rate varied from 0.98 to 0.17 cases per 100,000 of population with a tendency towards decrease. In the structure of morbidity local cases accounted for 46.8% and cases of infection contacted outside Moscow accounted for 53.2%. The morbidity level was low throughout the whole territory, only in two districts morbidity rate was significantly higher (P = 95%) than the average morbidity rate in the whole of the city. In the group of local cases morbidity had no pronounced seasonal character, in contrast to cases due to infection contacted outside the city which were mostly registered in summer and autumn. Persons aged 21-30 years were found to be the most affected age group. The general factors, and not the contact route, are supposed to play the main role in the realization of the mechanism of infection transfer. Under modern conditions, some manifestations of the epidemic process of typhoid infection can be detected only at the level of the whole city, or even the whole country.
该研究涉及1980 - 1988年期间莫斯科伤寒发病率情况。发病率从每10万人0.98例至0.17例不等，呈下降趋势。在发病构成中，本地病例占46.8%，在莫斯科以外感染的病例占53.2%。全市发病率水平较低，仅两个区的发病率显著高于全市平均发病率（P = 95%）。在本地病例组中，发病无明显季节性特征，而在莫斯科以外感染的病例大多在夏季和秋季登记。21至30岁的人群是受影响最严重的年龄组。一般因素而非接触途径被认为在感染传播机制的实现中起主要作用。在现代条件下，伤寒感染流行过程的一些表现仅在全市甚至全国层面才能被发现。
