What causes ringworm around the mouth?

Ringworm around the mouth may be caused by several factors: 1. Fungal infection: This is one of the most common causes, particularly infection with dermatophytes. The area around the mouth can become infected when it comes into contact with lesions from another person with ringworm, or through autoinfection from existing tinea infections such as hand or foot fungus. 2. Malnutrition: Deficiency in nutrients, especially vitamins, may trigger skin conditions such as pityriasis alba. When the condition affects the corners of the mouth, it can result in ringworm-like symptoms around the mouth. 3. Other skin diseases: Conditions such as pityriasis rosea, which may be triggered by herpesvirus infection or decreased immunity, can cause skin lesions around the mouth that resemble ringworm. Treatment approaches for these causes include using antifungal medications, supplementing essential nutrients, and managing the underlying skin condition. Additionally, maintaining good personal hygiene and avoiding cross-infection can help prevent and treat ringworm around the mouth.
