title: [Patterns in the epidemic process of scarlet fever in various territories differing in respect of climate and geography].
abstract: Observations carried out in Ashkhabad and Petrozavodsk permitted to reveal specific features of the epidemic process in scarlet fever at the territories differing in climato-geographic respect. This was expressed in a different level of morbidity, differences in the character of periodicity, seasonality and age structure of morbidity. Along with this there were noted differences in the spread of the carrier state of hemolytic streptococcus and of their biological properties, and also in the process of immunity formation in the population. The data obtained suggest that one of the causes of epidemiological differences in scarlet fever detected in the southern and the northern districts were peculiarities of the immunological reactivity of the population and a difference in the carrier state of the highly toxigenic streptococci.
