How to prevent and treat chickenpox?

Chickenpox is an infectious disease caused by primary infection with the varicella-zoster virus, with fever and rash as the main symptoms. It develops rapidly and is highly contagious, mostly in children under 15 years old. After recovery, the virus will remain dormant in the ganglia of patients who have had chickenpox. When the body's immunity is weakened or the patient is older, the virus can be easily reactivated, causing adult herpes zoster. Everyone is responsible for preventing and treating chickenpox.
