Ringworm Incubation Period: When Symptoms Appear

Ringworm (dermatophytosis/tinea) incubation varies by species and host immunity:

• Tinea corporis/cruris/pedis: 4–14 days typically.
• Tinea capitis: 10–21 days.
• Tinea unguium (onychomycosis): Weeks to months.

Some infections remain subclinical. Asymptomatic carriers can transmit. Early treatment (topical terbinafine, clotrimazole; oral for scalp/nails) limits spread. See a clinician for diagnosis (KOH prep, culture) if suspicious annular, scaly, pruritic lesions appear.
