Nail Fungus on the Rise: Experts Warn Against Shared Socks and Poor Foot Hygiene

MEDİCENTER TV / TÜRKİYE

Fungal infections increasingly affect vulnerable groups—and even long-haul drivers

Nail fungus, once seen primarily among the elderly and athletes, is now spreading among a broader population—including long-haul drivers—according to podiatry expert Muharrem Tosun from Üsküdar University’s Vocational School of Health Services. Sharing socks and slippers, wearing the same shoes for days without ventilation, and poor foot hygiene are fueling the rise in cases.

Tosun emphasizes that people with weak immune systems, diabetes, athletes, seniors, and those who work in constantly wet environments (such as janitorial staff) are particularly at risk. “Recently, we’ve also observed a significant increase in nail fungus among long-distance truck drivers, likely due to prolonged shoe use in limited conditions,” he added.

The main culprit: Dermatophytes

Nail fungus—also known as onychomycosis—is primarily caused by dermatophytes, particularly Trichophyton rubrum and Trichophyton mentagrophytes. These fungi invade beneath the nail plate, leading to discolored, thickened, or deformed nails. If left untreated, the infection can spread, causing further complications and discomfort.

Key prevention tips: Hygiene and foot care

Tosun outlines several essential practices for preventing nail fungus:

• Wash and dry your feet thoroughly every day, especially between the toes

• Avoid sharing socks, slippers, or nail care tools with others

• Choose socks made of cotton, bamboo, or silver-infused materials

• Do not wear the same shoes for several consecutive days—ensure proper ventilation

• Avoid prolonged exposure to damp environments

• Seek regular podiatric care for nail trimming and foot health

Risky spaces: Public gyms, pools, and showers

Public facilities such as gyms, pools, and saunas are common sources of fungal transmission. Tosun recommends always wearing personal flip-flops, drying your feet completely after use, and avoiding barefoot walking in communal showers. “These environments can serve as breeding grounds for fungi, so personal hygiene is non-negotiable,” he says.

Treatment options and the importance of early intervention

According to Tosun, treating nail fungus requires a comprehensive approach. Topical antifungal creams, oral antifungal medications, laser therapy, and mechanical cleaning (curettage) with specialized tools are among the most effective methods. “Podologists can physically remove the infected tissue and support nail regrowth. However, a multidisciplinary collaboration with physicians enhances success,” he explains.

Untreated infections reduce quality of life

Nail fungus is more than a cosmetic issue. Thickened and deformed nails can cause pain, make walking difficult, and negatively impact self-confidence. If left unchecked, the infection can also spread to surrounding skin, causing itching and irritation. Tosun warns, “These symptoms, while seemingly minor, can significantly diminish a person’s quality of life.”

A long but manageable treatment process

Finally, Tosun reminds patients that fungal nail infections, especially on the feet, thrive in dark, moist conditions. “This makes the feet particularly vulnerable,” he notes. “Treatment often requires patience—it may take over a year. Consistent hygiene and adherence to medical advice are crucial for a successful recovery.”
