Hand and foot tinea are caused by fungal infections, which are both contagious and recurrent. However, they are not related to sports activities or running. Even if one contracts hand or foot tinea, running is still possible, but it is best to avoid swimming to prevent repeated cross-infection. The standard treatment involves applying antifungal cream twice a day for at least one month continuously, which can completely eradicate the infection. After treatment, it is important to maintain a proper diet and lifestyle habits, avoid public baths and swimming, avoid contact with small animals, sand, and dirty water, and if affected by athlete's foot, it is advisable to wear gloves while washing feet to prevent cross-infection.
