Chickenpox is caused by the varicella-zoster virus and is highly contagious, usually spreading through the air. Once infected, a person can quickly transmit the disease to others within a small area. After a confirmed diagnosis, antiviral medication is needed, which can be administered orally or through infusion. During treatment, chickenpox may cause high fever; if this occurs, appropriate fever-reducing medication can be used. Throughout the treatment period, it is important to drink plenty of water, rest, avoid strenuous activity, and eat a light diet. Try to isolate during treatment and avoid contact with other children or elderly people to prevent cross-infection.
