Ringworm, despite its name, is not caused by worms but by a common fungal infection triggered by humid conditions. This summer, Maine is experiencing a surge in cases due to the heat and humidity, ideal conditions for the spread of this fungal disease.
Dr. Dora Mills, Chief Health Improvement Officer for MaineHealth, noted the seasonal uptick: “We tend to see more cases in the summer. With the recent hot and humid weather, we expect an increase in tinea infections.”
Tinea, caused by mold-like parasites that naturally reside on skin, hair, and nails, manifests as red, raised circles resembling parasitic worms. Commonly known as ringworm when on the body and athlete’s foot on the feet, these infections thrive in warm, moist environments.
Transmission occurs through direct contact with infected skin or animals; pets and livestock can also harbor the fungus. Treatment typically involves over-the-counter antifungal creams and efforts to reduce moisture. However, scalp infections may require prescription medications and special shampoos.
Dr. Mills cautioned against using steroid-containing products for itch relief, as steroids can exacerbate fungal growth. Instead, she recommended non-steroidal topical treatments for symptomatic relief, advising caution with children due to potential side effects like drowsiness from absorbed medications.
Preventative measures include thorough cleaning of items exposed to infected skin, such as towels and clothing. Maintaining dry, clean conditions on vulnerable areas of the body is crucial in preventing infection. Athletes, in particular, are advised to keep feet dry and ventilated, using foot powders and changing into dry shoes to minimize risks.
Dr. Mills emphasized the importance of personal hygiene practices, such as daily changes of socks and underwear, and avoiding shared athletic gear and public facilities without foot coverings.
Despite its alarming name, Dr. Mills reassured that ringworm is manageable with proper care and hygiene practices: “It’s a misleading name with an ‘ick’ factor, but with timely treatment and hygiene, it can be effectively controlled.”
