Athlete's foot is caused by a fungal infection. Fungi are contagious, so it is possible for the infection to spread to the face and even other parts of the body. In such cases, it is necessary to use antifungal creams. Currently, common treatments include Nystatin Ketoconazole Cream or Miconazole Nitrate Cream. However, the treatment period is relatively long, requiring at least one month of continuous medication, or continuing treatment for an additional ten days to half a month after the symptoms have completely disappeared. Athlete's foot itself also needs to be treated thoroughly, as only by completely curing athlete's foot can the spread of the infection to other parts of the body be prevented. It is recommended that personal items such as foot-washing towels and basins be used separately from other family members to prevent cross-infection. Items that have been used should be thoroughly disinfected and exposed to sunlight to kill the fungi.
