Chickenpox: Brief Version


What is chickenpox?

Chickenpox is a disease caused by a virus. Most likely, your child was around a child with chickenpox about 2 weeks before. Here's what you can expect:

  • At first, you'll see small, red bumps. These bumps may become thin-walled water blisters.
  • After that, you may see cloudy blisters or open sores.
  • In about a day, you may see them turn into dry, brown crusts.
  • More and more red bumps will crop up all over your child's body for about 4 or 5 days.

The disease can spread to other people until all the sores have crusted over. Most of the time, all the sores crust over about 5 to 7 days after the rash starts. It may take 2 weeks for all of the scabs to fall off.

How can I take care of my child?

  • Itching. Give your child a cool bath every 3 to 4 hours. Add 4 tablespoons of baking soda, oatmeal, or cornstarch to the tub of water. If the itching is very bad, or keeps your child from sleeping, give your child a pill called Benadryl. You can get this antihistamine at your drug store. You don't need a doctor's order.
  • Fever. If your child has a fever over 102° (39°C), give acetaminophen (Tylenol). Do not give aspirin or ibuprofen.
  • Sore mouth. Give soft foods and cold fluids. For babies, use a cup instead of a bottle. The nipple may hurt. Stay away from salty foods and citrus fruits. You can also have your child gargle or swallow 1 teaspoon of an antacid after meals.
  • Preventing infected sores. Trim your child's fingernails short. Also, wash your child's hands with an antibacterial soap often during the day.

Call your child's doctor right away if:

  • Your child has red skin, red streaks, or red rash.
  • Your child starts acting very sick.

Call your child's doctor within 24 hours if:

  • A scab looks infected (gets larger or drains pus).
  • The fever lasts over 4 days.
  • The itching is very bad and doesn't get better when treated.
  • You have other questions or concerns. If you take your child to a doctor's office, call ahead to let the staff know that you think your child has chickenpox.
