[Streptococcal respiratory infection in large organized children's collectives and experience in optimizing its prevention].

Epidemiological analysis of the manifestations of respiratory streptococcal infection in the all-year-round pioneer camp "Ocean" over 1984-1990 and in similar large organized groups of children revealed some common regularities manifested as consecutively repeating morbidity rises in acute respiratory diseases, tonsillitis, scarlet fever over a year (rotations 1-3 and 9). Time course of the disease incidence over each rotation (month) had a specific pattern as well. Trials of our newly developed system of prevention and treatment with tomicid showed its high effectiveness, which manifested by a drop in the morbidity level and changes in the structure and dynamics of respiratory streptococcal infection.
