Incidence of infectious diseases in children in the 1st 7 years of life

: The dynamics of changes in the occurrence of infectious diseases in 1180 children during the first 7 years of life has been studied. The possibility of dividing children into groups with rare and frequent occurrence of diseases as early as during the first years of life has been demonstrated. The group of children falling ill frequently determines, to a considerable extent, the morbidity level in infectious diseases among children of the corresponding age group.
