Usually, the disease will go away on its own and the doctor may only advise your child to use antihistamine for itching and other symptomatic treatments for healthy children. Patients are advised as followed:

• Quarantine themselves from school or work until spots have formed a scab in around 5 days after appearance of spots

• Drink plenty of fluid to avoid dehydration

• Use paracetamol and antihistamine to relieve fever and itch as necessary

• Do not scratch the blisters

• Bathe or shower with cool water then pat skin dry without rubbing

If your child has high risk of complication, a pediatrician may prescribe antiviral medicine to shorten the length of infection and reduce risk of complications if necessary.
