Is Nail Fungus Contagious?
Your feet are tough, carrying the weight of your body through each day. It may be surprising to learn that a microscopic organism called a dermatophyte can affect this robust part of your body. A type of mold fungus, dermatophytes are the reason behind many cases of nail fungus, an infection that changes the composition of your toenails.
General and aesthetic podiatrist Francine Rhinehart, DPM, specializes in treating nail fungus infections at her practice in the Oak Cliff neighborhood of Dallas. In fact, toenail fungus is one of the most common reasons that people see podiatrists. About 10% of Americans overall will experience a nail fungus infection, with that number climbing to 50% for those aged 70 and older.
The causes behind nail fungus
Your feet naturally carry a population of fungi that persist even with ideal hygiene, and you can acquire others from common surfaces that support fungal growth.
Most types of fungus generally thrive in warm, dark, and moist environments. In the case of the dermatophytes that affect your feet, the protein keratin is an ideal source of energy. Your nails are loaded with keratin. When dermatophytes penetrate beneath the surface of a toenail, they can grow unabated when conditions are right.
You’re more at risk of developing a fungal infection when you experience any of the following conditions:
- Poor blood circulation, such as peripheral vascular disease
- Diabetes
- Nail injuries
- Hyperhidrosis (excessive sweating)
- Psoriasis
- Weakened immune system
- Over age 65
- Regular use of artificial nails
Wearing closed-toed shoes for long hours can enhance the warm, moist environment for existing fungi, while frequent use of public showers or swimming pools could expose you to new sources of fungus.
Is nail fungus contagious?
Toenail fungus is very contagious, and it spreads easily when people touch infected surfaces. A common fungus is athlete's foot, which spreads through barefoot contact with contaminated surfaces in places like locker rooms, swimming pool decks, or public places where shoes aren’t usually worn.
Nail salons are another place where you may encounter dermatophytes. Ask about their sanitizing procedures, since a fungus could be transferred from clippers, files, and other tools that aren’t sufficiently sterilized.
If someone in your home has a fungal infection, you have an increased risk of contracting it, too.
Preventing and treating nail fungus infections
If you’re regularly exposed to high-risk environments for foot fungus, take extra care to protect your feet. While there are treatments for fungal infections, these conditions can be notoriously difficult to eradicate.
Over-the-counter solutions usually aren’t very effective, so a visit to Dr. Rhinehart is your best option when nail fungus takes hold. Your best option is avoiding an initial infection. Keep your nails fungus-free by following these suggestions:
- Avoid being barefoot in public areas by using flip-flops or shower shoes
- Keep toenails clean and trimmed
- Wash and dry your feet regularly
- Wash your hands thoroughly when touching an infected toe, since fingernails are vulnerable, too
- Limit use of nail polish and artificial nails
While you can reduce your risk of developing a fungal infection, you likely won’t be able to eliminate it. However, if you do get an infection, Dr. Rhinehart can help. She offers treatments with the Q-Clear™ laser system, a platform that’s particularly effective against nail fungus.
