Can tinea cause serious illness?
A fungus rarely spreads below the surface of the body to cause serious illness. Your body usually prevents this. However, people who have weak immune systems, such as people who have HIV or AIDS, may have a hard time getting rid of a fungal infection.
Tinea infections usually don't leave scars after the fungus is gone. Sometimes, people don't even realize they have a fungal infection and get better without any treatment.
