Candidiasis in Children

What is candidiasis in children?

Candidiasis is an infection caused by yeast called Candida. Candida normally causes no harm, and is found on the skin, vaginal area, and digestive system. But in some cases, it can overgrow. This can cause a rash, itching, and other symptoms.

What causes candidiasis in a child?

Yeast normally lives on and in the body and causes no harm. It’s found on the skin, in the digestive system (including the mouth and throat), and in the genital area. But it can cause an infection in certain conditions. This can happen when the skin is damaged, when it’s warm and humid, or when a child has a weak immune system. In some very sick children, it can infect deeper tissues or the bloodstream and cause serious illness. Antibiotics can also cause the yeast to overgrow. This is because antibiotics kill normal bacteria that usually prevent too much yeast from growing. Treatment with other medicines, such as corticosteroids, may also promote candidiasis.

Which children are at risk for candidiasis?

A child is at risk for candidiasis because of:

  • Hot, humid weather

  • Too much time between diaper changes

  • Poor hygiene

  • Taking medicines, such as antibiotics or corticosteroids

  • Health conditions that weaken the immune system

What are the symptoms of candidiasis in a child?

Symptoms can occur a bit differently in each child. And they vary depending on where the infection occurs. The most common symptoms include:



Skin folds or navel

  • Red rash

  • Patches that ooze clear fluid

  • Pimples

  • Itching or burning


  • White or yellow discharge from the vagina

  • Itching

  • Redness in the outside area of the vagina

  • Burning


  • Redness on the penis

  • Scaling on the penis

  • Painful rash on the penis

Mouth (thrush)

  • White patches on the tongue, top of the mouth, and inside of the cheeks

  • Pain

Corners of the mouth (perleche)

  • Cracks or tiny cuts at the corners of the mouth

Nail beds (paronychia)

  • Swelling

  • Pain

  • Pus

  • White or yellow nail that separates from the nail bed

The symptoms of candidiasis may be caused by other health conditions. Make sure your child sees their healthcare provider for a diagnosis.

How is candidiasis diagnosed in a child?

The healthcare provider will ask about your child’s symptoms and health history. They will give your child a physical exam. And the provider may scrape off a skin sample to check in a lab.

How is candidiasis treated in a child?

Most cases of candidiasis are mild and respond well to medicine. Treatment depends on where the infection is and how severe it is. For example:

  • Candidiasis on the skin may be treated with medicines to put on the skin, such as creams or gels.

  • Yeast infections in the vagina or anus can be treated with medicated suppositories.

  • Thrush may be treated with a medicated mouthwash or lozenges.

  • Severe infection or infection in a child with a weak immune system may be treated with anti-yeast medicines taken by mouth (oral) or vein (intravenous).

Mild cases may also go away on their own with improved hygiene.

What are possible complications of candidiasis in a child?

In rare cases, it can cause serious and life-threatening illness. This can happen when a child has a weak immune system, and the infection enters the bloodstream.

What can I do to prevent candidiasis in my child?

You can help prevent candidiasis by:

  • Keeping your child’s skin as clean and dry as possible

  • Changing diapers often

  • Allowing your child to have diaper-free time

  • Using antibiotics on your child only when needed

  • Watching for candidiasis symptoms after the use of antibiotics

  • Teaching your child about personal hygiene, such as how to brush their teeth and take a bath

  • Talking about prevention with your child’s healthcare provider if your child has a weak immune system

When should I call my child's healthcare provider?

Call the healthcare provider if your child has:

  • Symptoms that affect a large area

  • Symptoms that get worse

  • Signs of a skin infection, such as increased redness, warmth, swelling, or fluid

  • New symptoms

Next steps

Tips to help you get the most from a visit to your child’s healthcare provider:

  • Know the reason for the visit and what you want to happen.

  • Before your visit, write down questions you want answered.

  • At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you for your child.

  • Know why a new medicine or treatment is prescribed and how it will help your child. Also know what the side effects are.

  • Ask if your child’s condition can be treated in other ways.

  • Know why a test or procedure is recommended and what the results could mean.

  • Know what to expect if your child does not take the medicine or have the test or procedure.
