Tinea pedis medically refers to tinea pedis, which is not a lack of vitamins in the body, but a superficial fungal infection of the feet caused by fungi such as Candida albicans and Trichophyton rubrum that invade the intertoe, toes, heel, and lateral margins of the foot. Tinea pedis is mainly caused by dermatophytes such as Trichophyton rubrum and Trichophyton mustelii, but it can also be caused by fungi such as Candida albicans, resulting in blisters, itching, flaking, and erosion of the feet. The causative agent can spread from person to person, and people who often walk barefoot in public areas such as public bathrooms, swimming pools, and gyms, as well as people who share towels and foot wash basins with those who suffer from tinea pedis are prone to suffer from tinea pedis. When suffering from tinea pedis, you should clarify the pathogen under the guidance of a doctor, actively treat it, pay attention to personal hygiene in daily life, and do not share shoes and socks with others.
