Can athlete's foot cause cellulitis?

Athlete's foot is a fungal infection that commonly causes scaling, itching, and splits between the toes or along the sole. Those breaks can disrupt the skin barrier. Cellulitis is a bacterial infection of deeper skin and nearby tissue; it is different from the original fungal infection. The two can occur together, and treating athlete's foot helps reduce ongoing skin damage.

Keep feet clean and dry, dry carefully between the toes, change damp socks, and use an appropriate antifungal treatment as directed. Avoid sharing towels or footwear. Do not cover a weeping or cracked area with an occlusive dressing unless a clinician advises it. If redness or swelling develops, have the area assessed rather than assuming the fungal treatment is enough.

Seek same-day medical care for skin that becomes increasingly red, hot, swollen, tender, or rapidly enlarges, especially with fever, chills, or feeling unwell. Urgent assessment is also needed if redness reaches the face, the foot becomes difficult to move, or you have diabetes or reduced immune function. Rapidly worsening symptoms should not wait for a routine appointment.

Ask whether the changes fit athlete's foot, cellulitis, or both; which treatment is needed for each infection; and how to care for toe-web cracks while the skin heals. Ask what symptoms should trigger reassessment.
