title: [Epidemiological characteristics of meningococcal infection in a number of territories of the RSFSR (1969-1984)].
abstract: In this work the dynamics and morbidity level in respect of meningococcal infection at 11 territories of the RSFSR at the period of 1969-1984 are analyzed. The study covered altogether 16 cities and 211 districts. The role of big cities as the sources of infection spreading into rural areas and further "fixation" of this infection mainly in regions with a population of 60,000 and more had been established. The data on meningococcal morbidity and carriership among different age groups are presented. The study has shown a pronounced increase in the incidence rate of meningococcal infection among children aged up to 2 years, as well as an increase in the proportion of these children among patients with meningococcal infection in recent years.
