Ringworm Contagiousness and Treatment

Transmission and Prevention

The American Academy of Pediatrics recommends that individuals with ringworm avoid close contact with others until antifungal treatment has been initiated and is showing clinical response, typically within 24-48 hours after starting treatment, to prevent transmission in high-risk groups such as healthcare workers, childcare providers, and athletes in contact sports 1
Direct skin-to-skin contact is the primary mode of transmission, and hand hygiene with soap and water is essential for preventing transmission, particularly in household settings 1
