Tinea cruris is a disease caused by fungal infection, and there are many factors contributing to this condition. It can be completely cured through proper treatment, achieving a radical cure. Some people do not respond well to treatment, which is largely due to non-standard treatment, or re-infection after recovery. Generally, the application of common antifungal creams can completely cure the condition, and the treatment course should last at least one to two months. After recovery, one should avoid soaking in public baths or swimming to prevent cross-infection. If you have athlete's foot, make sure to wash socks and underwear separately, sun them, and disinfect them. Do not share towels or bath mitts. It is advisable not to keep small animals at home and to avoid working in overly damp or hot environments.
