Fungal nail infection is termed onychomycosis, and it may affect both fingernails and toenails

. While common in adults, fungal nail infection in children is rare. Only 2.5% of all babies and children are known to be affected by the fungal infection. However, the frequency of fungal nail infections in children has increased over the last few years (1) (2). Read this post as we bring to you the causes, signs and symptoms, home remedies, treatment, and prevention of fungal nail infections in children.

Key Pointers

  • Fungal nail infections in children can be caused by restricted ventilation in shoes, sharing towels, weakened immune system, and nail injuries.
  • Symptoms include changes in nail color, brittle or thinning nails, and debris under nails.
  • Treatment options include oral medications, topical antifungal treatments, laser treatment, photodynamic therapy, and nail removal.
  • Prevention methods include keeping feet and hands dry, wearing proper shoes, avoiding sharing personal items, and taking care of existing nail injuries.

Causes Of Fungal Nail Infection In Children

Fungal infection is caused by a variety of fungi belonging to the groups of dermatophytesiGroup of fungi that uses keratin protein to grow and is limited to skin, nail, and hair infections. , non-dermatophytic molds, and yeasts

. They cause infection when they have the right conditions to attach and propagate on a nail. The following factors can cause a fungus to infect a fingernail or toenail (3) (4) (5).

  1. Wearing shoes with restricted ventilation and socks that do not absorb perspiration, or boots all day may cause fungal toenail infection due to sweat.
  1. Sharing towels and napkins with others may cause the child to catch the fungus.
  1. Children who play in water or swim may have their hands and feet damp for a long time, thus increasing the risk of fungal infection.

  1. Children with diabetes, suppressed or weakened immune system, and problems with the circulation system may be at a higher risk.
  1. Some conditions, like psoriasisiAn autoimmune disorder that makes the skin itchy and scaly. and Down syndromeiA genetic condition where a person has an extra chromosome apparent through facial features, and speech and language problems. , increase the risk. Existing nail injuries may also increase the risk.
  1. An existing athlete’s foot in children (fungal infection in the foot) may cause the spread of infection to other toenails, from where it could reach fingernails.
  1. Humid and warm environments may increase the overall risk of fungal infection.

Signs And Symptoms Of Fungal Nail Infection In Children

The signs of toenail fungal infection vary from one child to another. While some may have toenail discoloration, others could have dull nails. Some of the common signs include (6):

  • The color of the nail might change to yellow, brown, or white
  • The nail may get dry or crumble or start to come off

Check regularly for early signs of nail infections such as changes in nail texture, swelling, itching, or dryness around a nail (12).

When To Seek Medical Help

Take your child to a doctor for immediate care in the following cases (17) (18).

  • Discoloration of nails
  • Pain or discomfort in the affected nail, particularly when applying pressure
  • Inflammation, itchiness, swelling, redness, or cracks on the surrounding skin of the affected nail
  • A blister with pus next to the affected nail

Diagnosis Of Fungal Nail Infection In Children

The dermatologist or doctor can diagnose fungal infection in nails through various steps:

  • Visual examination of the nail and skin around it to identify the symptoms of fungal infection.
  • A sample of the nail debris could be collected by nail scraping for analyzing it under a microscope.
  • Fungal culture tests may be done to identify the specific fungus and fungal infection (7).
  • In rare cases, the doctor might recommend a biopsy to rule out other nail conditions.

Diagnosis Of Fungal Nail Infection In Children 

The dermatologist or the doctor will examine the nail and skin around it for symptoms of fungal infection. A sample of the nail debris could be collected for analyzing it under a microscope. It can help conclusively diagnose fungal infection and the exact type of fungus causing the infection. (7).

Treatment And Home Remedies For Fungal Nail Infection 

The doctor may prescribe any of the following treatment methods for onychomycosis treatment (1).

  1. Oral medication: These are antifungal medicines administered orally. Common examples of these medicines are griseofulvin and terbinafine. Griseofulvin is the only drug that is approved by the US Food and Drug Administration (FDA) for pediatric use, but the medicine does not cure all cases of infection. Terbinafine is more effective but not approved by the FDA for pediatric use. Some studies find the drug to be safe for children. A doctor may consider administering terbinafine in the case of older children and teens. A joint study conducted by Stony Brook University and Weill Cornell Medicine in the US has revealed encouraging cure rates of 59% for fingernail infections and 38% for toenail infections. Nevertheless, never self-medicate with these medicines.

  1. Topical treatment: It involves topical application of antifungal ointments, creams, and lotions. The US FDA approves the use of the medicines Tavaborole, Amorolfine, Efinaconazole, and Ciclopirox to treat fungal nail infection. Your child’s doctor will prescribe the medicine needed to treat the fungal nail infection in the child (1) (7).
  1. Combination therapy: A doctor may consider the use of oral and topical antifungal medicines together. Combination therapy may be considered if one mode of treatment does not work or if the infection is severe. Combination therapy may work faster than using a single plan.
  1. Nonpharmacological approaches include:
  • Laser treatment
  • Photodynamic therapyiA treatment involving a combination of light and light-activated medications to get rid of abnormal cells, such as in cancer.
  1. Nail removal: The doctor may suggest the removal of the nail when other methods of treatment do not yield results. Nail removal can be achieved by the application of chemicals that cause the nail to fall. If this process is not possible, then the doctor may perform minor surgery to remove the infected nail from the nailbed to treat a nail bed infection.

Some substances and compounds can be applied topically to the affected nail at home.

These home remedies for fungal nail infection have anecdotal evidence, but more research may be needed to support them scientifically.

  1. A study found that the topical application of Vicks VapoRub for children could treat the affected nail. The cure happened when Vicks VapoRub was applied once a day for 48 weeks (11 months) (8).

  1. Application of tea tree oil with a cotton swab twice daily for six months may help provide relief (9).
  1. Regular application of oregano oil may help treat toenail fungus. Oregano oil contains a compound called thymol, which is known for its antifungal properties (10).
  1. Snakeroot extract contains antifungal properties. The topical application could help treat fungal nail infections (11).
  1. Application of plain or white vinegar may also be useful in treating fungal nail infection (12).

protip_icon Quick tip
Fungus may reside on footwear. On recovering from nail fungus (especially toenail) discard the footwear used before and during the treatment to prevent a re-infection (13).

If your doctor prescribes a medicine for the infection, then stop the use of home remedies since it may interfere with the effective action of the medicinal compound.

Can Fungal Nail Infection Be Prevented?

It is possible to prevent fungal nail infection in children by following a few simple measures.

  • Parents should see that their children stay away from pets and individuals who have a fungal infection.
  • Soap, shampoos, towels, and combs of your children should not be used by others to prevent the spread of fungal infection from others.
  • Teach your children about good hygiene practices. For instance, washing hands with soap, keeping nails trimmed, and changing socks regularly can help prevent infections.
  • If your child sweats a lot or you live in a humid climate, then you may consider using talcum powder to absorb perspirationiRelease of fluids from the body’s sweat glands, commonly called sweating. .

Alternating shoes (to allow them to dry) and sprinkling antifungal powder in your shoes can prevent fungal growth inside them and subsequent fungal toenail infection (13).

Frequently Asked Questions

1. Can apple cider vinegar help get rid of nail fungus?

Apple cider vinegar is believed to lower the skin’s pH and thereby reduce the levels of fungus on the nail and feet thereby eliminating the infection. However, there is no specific medical research that claims apple cider vinegar to be effective against toenail fungus (14).

2. Do nails grow back after a fungal infection?

Yes, nails usually grow back after an infection has been successfully treated, however, the nail may appear infected or unhealthy until it grows out. Fingernails may take four to six months, while toenails usually take 12 to 18 months to grow out (7).

3. What foods should my child avoid if they have a fungal infection?

A diet high in refined carbohydrates, sugar, or yeast may make them prone to fungal infections such as candidiasis (15). Reduce your child’s intake of these foods when they already have an infection.

4. Can a vitamin deficiency cause toenail fungus?

A deficiency of vitamin D may make you more susceptible to fungal infections (16)

5. Is nail fungus contagious?

According to board-certified dermatologist Dr. Alpana Mohta, “Nail fungus, or onychomycosis, is contagious. It can spread through direct contact with infected nails or indirectly through contact with contaminated surfaces like floors, shoes, or nail clippers.”

Fungal nail infection may develop in children when their hands and feet are damp for long, weakened immune systems, or live in warm and humid environments. As a result, they may experience a change in color of the nails, rough nails, or debris formed under the nails. Consult a doctor for any fungal nail infection. The treatment procedure may involve medications, topical ointments, or laser therapy. Home remedies, such as tea tree oil and oregano oil may also work. It is important to follow the full course of treatment suggested by the doctor to prevent a relapse of the infection. Also, maintaining good hygiene and managing perspiration can minimize the spread of infection.
