Tinea cruris is a type of fungal infection. This disease is highly contagious and recurrent. Generally, it can be completely cured with proper treatment. If there is a recurrence, it is often related to incomplete healing or re-infection after recovery. Treatment is usually simple, with the most common treatment being the application of antifungal creams. However, the treatment course must be long, lasting at least one to two months. After recovery, it is important to prevent recurrence by avoiding public baths and swimming pools. If you have athlete's foot, make sure to wash socks and underwear separately and avoid sharing towels or washcloths. It is advisable to bathe more frequently during the treatment period.
