"CHILDREN WITH RECURRENT INFECTIONS" AS A MANIFESTATION OF PRIMARY IMMUNODEFICIENCY

In modern pediatrics, children with recurrent infections are commonly referred to as frequently ill. Factors contributing to the development of frequently ill children, as described in various literature, include delayed development of the immune system, anatomical and physiological features of the respiratory tract in children (structural characteristics of the bronchi), nutrition, and living conditions. It is believed that frequently recurring or persistent infectious conditions are the main manifestation of primary immunodeficiency.
