fungal skin in children

Overview

A fungal skin infection is a common skin problem caused by tiny living organisms called fungi. These germs can live on the outer layer of the skin and cause red, itchy, scaly patches. In children, these infections often appear on the scalp, feet, groin, or other warm, moist areas of the body.

Yes, fungal skin infections are one of the most common skin problems in children. Many will have at least one during childhood.

Fungal skin infections can affect children of all ages, but they are especially common in school-age children. Some types, like ringworm of the scalp, are more often seen in younger children, while athlete's foot is more common in teens and older children.

Symptoms

Common symptoms

• Red, scaly, or flaky patches on the skin
• Itching, which may be worse after sweating
• A ring-shaped rash with a clear center (often called ringworm)
• Cracked, peeling, or sore skin between the toes
• White or yellowish patches on the nails
• Bald patches on the scalp with scaly or red skin

Symptoms in children

• Patches may appear on the scalp and cause hair loss or broken hairs
• Rashes may spread quickly through school or daycare
• Children may complain of itchiness more than older children
• Patches can appear anywhere on the body, including the face and neck

Symptoms in older adults

• Fungal infections in older adults are more likely affect the feet, groin, or nails
• Skin may become thickened, cracked, or discolored
• Older adults may have less obvious itchiness but more skin damage from scratching

Causes

Main causes

• Tiny fungi (like dermatophytes) that live on the outer layer of the skin, hair, or nails
• Direct skin-to-skin contact with an infected person or animal
• Touching contaminated objects such as towels, combs, hats, or shower floors
• Warm, damp environments where fungi grow easily

Risk factors

• Sharing personal items like towels, combs, or sports equipment
• Walking barefoot in damp public places like swimming pools or changing rooms
• Wearing tight, non-breathable clothing or shoes for long periods
• Sweating heavily
• Having a weakened immune system due to illness or certain medicines
• Close contact with pets or farm animals that may carry fungi

When to see a doctor

See a doctor urgently if:

• The rash is spreading quickly or covering a large area of the body
• The scalp is affected and there are bald patches
• Your child has a fever or seems unwell
• The skin is very swollen, painful, or leaking fluid
• The infection is not getting better after using pharmacy treatments for one week

Book a routine appointment if:

• Your child has a new skin rash that does not go away after a week or two
• The rash keeps coming back
• The rash is itchy or uncomfortable and affecting sleep or play
• Other family members or close contacts have the same rash

Diagnosis

A doctor or nurse can usually diagnose a fungal skin infection by looking at the affected skin. They may ask questions about your child's symptoms, activities, and contact with other people or animals.

Tests that may be done

• Sometimes a doctor will gently scrape a small sample of skin or hair to look at under a microscope
• A fungal culture may be done, where the sample is sent to a laboratory to see if fungi grow
• Rarely, a small piece of skin (a biopsy) is taken if the diagnosis is unclear

What to expect at your appointment

The doctor will examine the rash and may use a special light to check for certain types of fungal infections. Tests are usually painless, though a scraping may feel slightly uncomfortable. Results can take a few days if a culture is sent to a lab.

Treatment

Treatment for fungal skin infections depends on the type of infection, where it is, and your child's age. Most infections are treated with antifungal creams or liquids applied directly to the skin. For scalp infections, oral medicines are often needed because creams cannot reach the hair roots. It is important to follow the full treatment course even if symptoms improve.

Self-care at home

• Keep the affected area clean and dry, especially after bathing
• Wash towels, bedding, and clothes in hot water
• Avoid sharing towels, combs, brushes, hats, or clothing until the infection is gone
• Dress your child in loose-fitting, breathable fabrics like cotton
• Use a separate towel for the infected area and wash it regularly
• Avoid scratching, as this can spread the infection and cause breaks in the skin

Medical treatments

Doctors may prescribe antifungal creams, ointments, lotions, shampoos, or oral medicines. The type of medicine and how long it is used depends on the kind of fungal infection and its location. Always consult your doctor or pharmacist about the best treatment for your child and follow their instructions exactly. Do not use leftover medicines from other family members.

When is surgery considered?

Surgery is almost never needed for fungal skin infections. In very rare cases of fungal nail infection that does not respond to other treatment, a healthcare professional may need to remove the affected nail.

Living with this condition

While your child has a fungal skin infection, help them follow the treatment plan and keep the affected skin clean and dry. It can be helpful to keep nails short and clean to avoid scratching. Make sure your child washes their hands after touching the affected area to prevent spreading the infection.

Lifestyle tips

• Change socks and underwear daily, and let shoes air out between wears
• Wear sandals or shower shoes in public showers and pool areas
• Wash sports uniforms, towels, and bedding regularly in hot water
• Check pets and other children in the household for signs of infection

Diet and exercise

There is no specific diet to cure a fungal skin infection. Eating a balanced diet helps support the immune system, but it does not replace medical treatment. Your child can continue normal activities and play, but they should avoid swimming pools and shared changing rooms until the infection is no longer contagious or as advised by a doctor.

Mental health and emotional wellbeing

Skin infections can sometimes make children feel self-conscious or embarrassed, especially if the rash is visible. Reassure your child that this is a common problem and that treatment helps. Talk openly about what is happening and encourage questions. If your child seems worried, withdrawn, or anxious, consider speaking with a trusted healthcare professional for support.

Prevention

Fungal skin infections are very contagious, but there are ways to lower the risk. Good hygiene and avoiding shared personal items are the most effective steps. Teach children to wash their hands regularly and not to share combs, hats, towels, or sports equipment.

Vaccines

There is currently no vaccine for fungal skin infections.

Screening programmes

There is no routine screening for fungal skin infections. If you suspect your child has been exposed to ringworm or another fungal infection, watch for signs such as red or scaly patches and see a doctor if they appear.

Complications

If left untreated

• The infection may spread to other parts of the body or to other people
• Intense scratching can lead to breaks in the skin and a bacterial infection
• Scalp infections can cause temporary hair loss, which may become permanent if untreated for a long time
• In rare cases, a fungal infection can spread deeper into the skin or body in children with weakened immune systems

Long-term outlook

With proper treatment, most fungal skin infections in children go away completely within a few weeks. Even scalp infections, which take longer to treat, usually respond well. Rarely, the infection may come back, but this can be managed with good hygiene and further treatment. Most children return to normal activities without lasting skin damage.
