Abstract
<jats:p>Recurrent respiratory infections in children remain one of the leading problems in modern paediatrics, placing a significant medical and social burden. Acute respiratory diseases account for up to 65% of paediatric pathology, whilst true immunodeficiency is found in only a small proportion of patients. In most cases, recurrence is due to multifactorial influences, including functional immaturity of the immune system, environmental factors, nutritional deficiencies and concomitant allergic conditions. The aim of this study was to summarise current data on the epidemiology, risk factors and prevention of recurrent respiratory infections in children. The methodology was based on the analysis of 44 scientific sources using systematic search and content analysis. The results confirm the important role of local immunity, particularly secretory immunoglobulin A, as well as the influence of lifestyle, physical development and nutritional status. The importance of vitamins A and D has been established, as deficiency in these vitamins is associated with an increased frequency and severity of infections. The efficacy of probiotics, bacterial lysates and podotimod in reducing the frequency of episodes has been demonstrated. Conclusion. Effective management of children requires an individualised approach, taking into account risk factors and immune status. The integration of non-pharmacological measures and evidence-based immunomodulation is key to reducing the frequency of illnesses and preventing their chronicity.</jats:p>
