Anyone can develop fungal nails. Up to 10% of people develop fungal nails during their life. Some things that can make it easier for people to develop fungal nails include:
- Age
- Poor circulation
- Bad diet
- Male
- Illness or disease
- Nail damage
You can contract a nail infection by direct contact, such as on the shower floor, or by sharing infected items of clothing like used socks or footwear.
Fungal infections can enter nails easier when it is wet. Wearing closed in footwear like gumboots or tight shoes can make this worse. Likewise, very sweaty feet can also be a problem.
