How common are fungal nail infections?

ANSWER

Fungus is the cause of up to half of all nail infections. It’s very common among adults 60 and older -- about 3 out of 4 seniors have the problem, while only 1 of 5 younger adults are affected.

You can get a fungal nail infection on your fingernail as well, but it’s much more likely to show up on your toenails.
