Nail Fungus
Yes, that fungus making your nails look funky is highly contagious. According to the American Academy of Dermatology, it’s especially transmissible in warm, damp environments.
Plus, sharing your shoes with someone when you have an infection can also cause it to spread.
If and when you have fungus on your feet, make sure to avoid walking around barefoot—and generally, you should be extra careful about wearing shower shoes at the gym and double-checking your friends’ feet before you share shoes with them.
