Candidiasis in Children
What is candidiasis?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?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. Medicine with antibiotics or corticosteroids can also cause the yeast to overgrow. This is because those medicines kill normal bacteria that usually prevent too much yeast to grow.
Who is 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, such as diabetes, cancer, or HIV
What are the symptoms of candidiasis?
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
Corners of the mouth (perlèche)
Nail beds (peronychia)
The symptoms of candidiasis can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.
How is candidiasis diagnosed?The healthcare provider will ask about your child’s symptoms and health history. He or she will give your child a physical exam. And the healthcare provider may scrape off a skin sample to check in a lab.
How is candidiasis treated?
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 is treated with ointment.
- 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 oral anti-yeast medicines.
What are possible complications of candidiasis?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.
Can candidiasis be prevented?
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
- 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
