[Epidemiology of diphtheria in the RSFSR during mass immunization over many years].
The work defines the characteristic epidemiological features of diphtheria in the RSFSR at the present moment when a high level of antitoxic immunity is generally determined in children. With the diphtheria morbidity level having, on the whole, a sporadic character in the RSFSR, the intensification of the epidemic process has been found to occur in some regions. Changes in the ratio of morbidity rates among the urban and rural population are observed, the morbidity rate among the latter have the tendency towards increase. At present the characteristic feature of diphtheria is the prevalence of adults in the general morbidity structure. An important fact is a permanently high level of toxigenicity in Corynebacterium diphtheriae. As before, autumn is the season of the highest morbidity level.
