Chickenpox is a self-limiting disease, and when there are no complications, treatment generally focuses on symptomatic relief. During illness, isolation should be maintained to prevent infection and enhance care, such as frequently changing underwear, trimming the child's nails, and wearing gloves to prevent scratching. Keep the air well-ventilated, provide sufficient fluids and easily digestible food. If a secondary bacterial infection occurs, antibiotic treatment should be administered. The child should be isolated until all the rash has crusted over.
