[The main trends in a diphtheria epidemic process and the potentials for its elimination in a large city]. / Osnovnye tendentsii épidemicheskogo protsessa difterii i vozmozhnosti ee likvidatsii v usloviiakh krupnogo goroda.

In recent years the tendency towards the activation of the epidemic process of diphtheria, i.e. the appearance of cases of diphtheria simultaneously with the increased levels of circulation of toxigenic and nontoxigenic Corynebacterium diphtheriae and with antitoxic immunity characteristics in children and adults constantly remaining low, has been registered. For the effective control of diphtheria, the profound study of such problems as bacterial carriership, antibacterial immunity and the development of supplementary means of specific prophylaxis is necessary.

[Seasonality of Sonne dysentery among organized and unorganized groups of children in years with different morbidity levels]. / Sezonnost' dizenterii Zonne sredi organizovannykh i neorganizovannykh detei v gody s raznymi urovniami zabolevaemosti.

Differences in the monthly distribution of morbidity in Sonne dysentery among children of preschool age in children's institutions and among those not attending such institutions have been revealed. In years characterized by a high morbidity level, the epidemic process develops simultaneously among all children with some prevalence in its activity being observed from January to August among children not attending children's institutions and from September to December among institutionalized children. In years characterized by a low morbidity level, the rise of morbidity among children aged up to 3 years, both seasonal and not connected with the season (in January), is determined by the rise of morbidity among those children who attend children's institutions, while among noninstitutionalized children aged 4-6 years the seasonal rise of morbidity begins and becomes manifest earlier.
