Are Fungal Nail Infections Contagious? (And How to Treat Them)

You might not think twice about a discoloured or thickened toenail, but fungal nail infections are more than just a cosmetic issue. They're highly contagious, often stubborn to treat, and can easily spread to others or even to your other nails if not addressed early.

At Treat Your Feet, we help people across Wombwell (Barnsley) and Morley (Leeds) manage fungal infections safely and effectively. In this blog, we’ll explain what causes them, how they spread, and what you can do to get rid of them for good.

What Is a Fungal Nail Infection?

Fungal nail infections—also known as onychomycosis—are caused by microscopic fungi that thrive in warm, moist environments. They typically enter the nail through tiny cracks in the nail or surrounding skin, often after damage or prolonged exposure to damp conditions.

You might have a fungal nail infection if you notice:

• Yellow, brown, or white discolouration

• Thickened or brittle nails

• A distorted nail shape

• A slightly foul odour from the nail

• Pain or pressure in the nail area (especially in severe cases)

• 
  

Are Fungal Nail Infections Contagious?

Yes, they are. Fungal spores can spread through direct and indirect contact, including:

• Shared showers or changing rooms (like in gyms or swimming pools)

• Walking barefoot in public places

• Sharing nail tools (like clippers or files) with someone infected

• Wearing sweaty socks or tight shoes for long periods

The infection can also spread to other toenails, the skin on your feet (commonly causing athlete’s foot), or even to fingernails in some cases.

How to Prevent the Spread of Fungal Infections

To reduce the risk of spreading or contracting fungal nail infections, try the following:

✅ Always wear flip-flops or sliders in communal areas

✅ Change socks daily and wear breathable footwear

✅ Avoid sharing towels, socks, or nail tools

✅ Keep feet clean and dry—especially between the toes

✅ Disinfect clippers and files after each use

How to Treat a Fungal Nail Infection

Unfortunately, fungal nail infections rarely go away on their own. The earlier you begin treatment, the easier they are to manage. At Treat Your Feet, we offer professional fungal nail care and guidance tailored to your condition.

Here are the most common treatment routes:

1. Topical Treatments

• Antifungal nail lacquers or creams may be effective for mild cases

• Require consistent, long-term application

• Often used in combination with other treatments

2. Oral Antifungal Medication

• Prescribed in more persistent or widespread infections

• Can take several months and may have side effects

• Requires monitoring by a healthcare professional

3. Professional Nail Debridement

• We reduce the thickness of the infected nail to improve comfort

• Allows topical treatments to penetrate more effectively

• Helps improve appearance and speed up recovery

4. Laser or Advanced Treatments (if needed)

• Available via referral in more severe or recurring cases
