Varicella

What is varicella?

Varicella, or chickenpox, is an infection caused by the varicella virus. Chickenpox is spread when an infected person coughs or sneezes. It is also spread when you touch the fluid that comes out of chickenpox blisters.

What are the signs and symptoms of chickenpox?

A rash usually appears on your child's chest, back, and scalp first. The rash then spreads to the arms and legs. It begins as itchy, red bumps. The bumps form blisters that are filled with fluid. The blisters then break and crust over. New blisters may continue to form for up to 4 days. It takes about 2 weeks for all the crusts and scabs to fall off. Your child may also have any of the following:

  • Fever
  • Headache
  • Tiredness
  • Mouth sores

How is chickenpox diagnosed?

Your child's healthcare provider can usually diagnose chickenpox based on your child's symptoms and physical exam.

    • Apply calamine lotion on your child's rash. Follow the directions on the label. Do not use this lotion on sores inside your child's mouth.
    • Give your child baths in lukewarm water. Add ½ cup of baking soda or uncooked oatmeal to the water. Let your child bathe for about 30 minutes. Do this several times a day.
    • Trim your child's fingernails. Put gloves or socks on his hands, especially at night. Wash his hands with germ-killing soap to prevent a bacterial infection.
    • Keep your child cool. The itching can get worse if your child sweats.
  • Help relieve painful mouth sores. You may be given medicine to put on your child's mouth sores. These may include numbing gels or an antacid solution. Use these medicines before your child eats or drinks. Avoid spicy, salty, hot, or sour foods.
  • Give your child liquids as directed to help prevent dehydration. Ask how much liquid your child should drink each day and which liquids are best for him. Good liquids include water, juice, or broth. He may need an oral rehydration solution (ORS). An ORS has the right amounts of water, salts, and sugar your child needs to replace body fluids. You can buy ORS at most grocery stores and pharmacies.
  • Help your child rest as much as possible and get plenty of sleep.
