Chickenpox is an infection caused by a virus (varicella-zoster). It’s easily spread from person to person. We usually see chickenpox in children age 15 years and younger, but adults can get it too.

Symptoms last about 5 to 15 days and include:

  • An itchy, blistering rash
  • Fever
  • Headache

The rash:

  • Appears 10 to 21 days after exposure to the virus.
  • Produces small, fluid-filled blisters that break open and form crusts.

When first infected, you or your child might not have symptoms. During this time, you can spread the virus to others without knowing it. You’re contagious until 1 to 2 days before the rash appears.

Home treatment helps reduce itching and eases other symptoms. We may also prescribe antiviral medicine. Be sure to let us know if you or your child has chickenpox symptoms.


The first symptoms of chickenpox are fever, stomachache, headache, or loss of appetite.

Within 2 to 4 days, you develop a rash with fluid-filled blisters. It begins on the trunk, face, and scalp, then spreads over the body.

Within 1 or 2 days after the first blisters appear:

  • They burst and scab over.
  • New blisters develop in cycles.

Blisters can appear:

  • Inside the mouth
  • On the eyelids
  • Inside the ears
  • On the genitals, or inside the vagina

Unless you or your child scratches and infects the blisters, you won’t have scars after the blisters heal.

Children and adults who have eczema may have more severe blisters.

Symptoms usually last 5 to 15 days.

Possible Complications

Call us right away if you think your child (or you) has chickenpox. Blisters can become infected. This makes treatment more difficult and may make the illness last longer.

Early treatment can reduce the risk of rare but serious complications, such as:

  • Pneumonia
  • Arthritis
  • Heart infection (myocarditis)

Once you have chickenpox, the virus remains inactive (dormant) in your body after you get well. It can be triggered later in life, causing a condition called shingles.

Risk Factors

You and your child are at highest risk of getting chickenpox if you:

  • Haven’t had the chickenpox vaccine.
  • Have a weakened immune system (such as from chronic illness or medicine like steroids).

If an adult or child who is vaccinated develops chickenpox, the symptoms are usually mild. But they can still pass chickenpox to others.

Causes and Diagnosis

Chickenpox is caused by the varicella-zoster virus. It spreads when an infected person sneezes or coughs.

You or your child can be infected when you:

  • Breathe in the virus
  • Touch the fluid from blisters

You’re most contagious 1 to 2 days before the rash appears. You or your child might not have any symptoms yet. You might not realize that you’re spreading the virus to others.

We diagnose chickenpox by looking at the rash with blisters. If it’s not clear, we might order a blood test to confirm the diagnosis.

When a pregnant woman gets chickenpox, she may pass the infection on to her unborn baby. Chickenpox is usually severe in a newborn, especially if the mother hasn’t had it or been vaccinated.


The chickenpox vaccine is our best prevention tool.

Children get 2 vaccine doses at:

  • 12 to 15 months old.
  • 4 to 6 years old.

For children ages 12 months through 12 years, the second dose is given 3 months or more after the first dose.

For people age 13 years and older, the second dose is given 4 weeks or more after the first.

If you or your child were recently exposed to chickenpox and haven’t been vaccinated, we may recommend vaccination. This may prevent chickenpox or make symptoms milder.

Do not get the chickenpox vaccine if you:

  • Are pregnant.
  • Had an allergic reaction to a previous chickenpox vaccine.
  • Are already immune to chickenpox.
  • Have a severely weakened immune system.

If you have a weakened immune system, let us know before being vaccinated.

Home Treatment

Home treatment can soothe your child’s chickenpox symptoms. It’s usually all the care that is needed.

Reduce your child’s itching with an:

  • Oatmeal bath in lukewarm water.
  • Anti-itching lotion (Calamine).
  • Oral antihistamine, such as Benadryl.

To soothe other symptoms:

  • Reduce fever or pain with acetaminophen or ibuprofen.
  • Keep the fingernails trimmed short. Scratching the blisters can cause an infection.
  • Make sure your child gets plenty of rest, especially during the fever phase.

Do not give aspirin to a child with chickenpox. It can cause a serious condition called Reye's syndrome. If your child takes daily aspirin for another condition, let us know.

If you haven’t had chickenpox or been vaccinated, don’t take care of someone who has chickenpox.

Avoid touching the fluid from your child’s blisters. It could infect you with the chickenpox virus.

Don’t let your child return to school or play with other children until all the blisters have dried out or become crusty.

An adult should not return to work or public places until his or her chickenpox blisters crust over.

Treatment and Medications

We may prescribe an antiviral medication if your child or you have:

  • Severe chickenpox
  • Eczema
  • Another skin condition
  • A weakened immune system

Antiviral medication is most effective when taken within 72 hours after the rash first appears.

We might also give family members antiviral medication to prevent an outbreak in your home.

When to Call Us

If you think your child (or you) was exposed to chickenpox, and you haven’t had chickenpox or the vaccine, call us. You'll need to be vaccinated right away.

If your child (or you) develops a rash of fluid-filled blisters, call us. Most children do not need treatment. We can determine if treatment is needed for your child and others in your household.

If you have an emergency medical condition, call 911 or go to the nearest hospital. An emergency medical condition is any of the following: (1) a medical condition that manifests itself by acute symptoms of sufficient severity (including severe pain) such that you could reasonably expect the absence of immediate medical attention to result in serious jeopardy to your health or body functions or organs; (2) active labor when there isn't enough time for safe transfer to a Plan hospital (or designated hospital) before delivery, or if transfer poses a threat to your (or your unborn child's) health and safety, or (3) a mental disorder that manifests itself by acute symptoms of sufficient severity such that either you are an immediate danger to yourself or others, or you are not immediately able to provide for, or use, food, shelter, or clothing, due to the mental disorder.
