Acute bronchiolitis, as an inflammatory disease of the lower respiratory tract, in most cases involves the small bronchi and bronchioles and develops in children under 2 years of age (frequently in children under 1 year). The symptom complex of acute bronchiolitis includes lower respiratory tract obstruction, manifesting against the background of acute respiratory viral infection (or exposure to other irritants), accompanied by cough and symptoms of respiratory failure.Annually, 150 million cases of bronchiolitis are registered worldwide (11 cases per 100 infants), of which 7-18% require inpatient treatment and 5-20% require intensive care unit hospitalization. The seasonal peak of bronchiolitis incidence in our country continues from November to April.Sufficient data on the diagnosis and treatment of children with acute bronchiolitis (AB) has been accumulated in the literature. However, this information is formed mainly on the general population of patients with AB and is often not applicable to patients with severe disease.The purpose of this descriptive review is to provide information to practicing physicians and students about acute bronchiolitis in children.The aimof this review is to systematize current data from the scientific literature on OB in children and to provide a comprehensive review of its clinical presentation, differential diagnosis, treatment, and preventive measures. This review may subsequently be used by practicing physicians and students in their work with information on OB in children.Keywords:acute bronchiolitis, etiology, pathogenesis, differential diagnosis, clinical presentation, treatment.
