THE COURSE OF CHICKENPOX IN CHILDREN IN DIFFERENT AGE GROUPS.

Abstract

Chickenpox (varicella) is an acute infectious disease common among children, caused by the Varicella zoster virus (VZV). The clinical course of the disease varies significantly depending on age groups: in infants and immunocompromised children, it is more severe and can be complicated; in healthy preschool children, it is often mild, but secondary bacterial skin infections are common; in adolescents, fever and general intoxication are more severe, and the risk of pneumonia and neurological complications is high. Epidemiological studies conducted in Uzbekistan show that chickenpox is most common in children aged 1–9 years, and the disease is more severe in unvaccinated children. International sources confirm the high effectiveness of the two-dose vaccination strategy, which sharply reduces the incidence and severity of complications. The article scientifically analyzes the clinical course of chickenpox in different age groups, complications, diagnostic methods and treatment principles, as well as the effectiveness of preventive measures used in Uzbekistan and world experience. These analyzes are important for identifying risk groups in pediatric practice, preventing severe complications, and improving vaccination strategies.
