Fungal Infections

Written by Kristina Collins, M.D., FAAD

Fungal infections can take on many forms and are super common during adolescence. Red, itchy rashes in the groin area (tinea inguinal) or scaling on the bottom and sides of the feet (tinea pedis) can both be due to fungal infections. Commonly, these problems are referred to as jock itch or athlete’s foot. Fungus is highly contagious. It grows and thrives in moist, sweaty environments so the groin and feet are the most common locations for fungal overgrowth. When circular, itchy red patches occur on the body, tinea corporis, or ringworm may be to blame.

If you think you may have a fungal infection:

  • Make sure to keep the area as dry as possible.
  • You can wipe off excessive sweat and use sweat-absorbing powders to maintain a dry environment and wear sweat-wicking socks/clothing to help absorb moisture.
  • Wear flip-flops in the gym shower to avoid possibly exposing your feet to other people’s fungus.
  • Grab an over-the-counter anti-fungal cream and apply it twice daily to the affected area for two weeks.
  • If this doesn’t do the trick, you may need to consult your doctor.
