Definition
Fungal infections are very common on both fingernail and toenails. It is a living organism that thrives in dark, damp environments such as under and around nails. Toes are more likely to be affected by fungus since it is attracted to a dark and damp environment which is more common on the foot than on the hand.
Cause
Trauma to the nail.
Poor hygiene of the foot.
Susceptibility (such as decreased immunity) of the person who has contact with the fungus.
Treatment & Prevention
Wear natural cotton Toe socks because they absorb moisture from your feet (from sweating) and provide good ventilation.
Wear breathable shoes.
When drying your feet, only use your towel once on your fungus area, and then wash it.
Do not share your towels or wash cloths with others; you may spread or collect spores.
Use a paper towel or toilet paper to dry your affected area, and throw away when finished.
Do not use nail polish until the disease is gone.
File the infected nail thin so that a local treatment can penetrate the nail more effectively.
