Rain rot surfaces in humans across Europe, raising STI questions
Rain rot (dermatophilosis) is normally an animal skin infection caused by Dermatophilus congolensis, but a small European outbreak among men who have sex with men has prompted discussion of possible human-to-human transmission and a wider STI classification; most exposures stem from contact with animals, yet prolonged intimate skin-to-skin contact could spread the bacteria. Symptoms include crusty, itchy patches on the face and genitals; diagnosis is by skin samples or cultures, and treatment with topical or oral antibiotics is usually effective. The condition is rare and typically not serious, but awareness and proper hygiene—especially for those working with livestock or frequenting humid venues—are advised.
