Infected Toenail Causes & Risks


Paronychia occurs when a bacteria or fungus enters damaged skin surrounding the nail. The damaged skin can be torn cuticles, cuts, or cracks.

Risk Factors

A risk factor is something that increases your chance of getting a disease or condition.

The risk of paronychia increases with:

  • Diabetes
  • Work that requires frequent exposure to chemical solvents or water (eg, food service, cleaning, dentistry, bartending, hairdressing, nursing)
  • Habitual nail-biting
  • Overly aggressive manicuring
