Key Points:

Minnesota is experiencing the largest known outbreak in the U.S. of TMVII, a sexually transmitted fungus that causes genital ringworm, according to the Minnesota Department of Health (MDH).
TMVII was first identified in New York City in June 2024, with Minnesota confirming its first case 13 months later; over 30 cases have since been reported in the Twin Cities metro area.
The infection causes itchy, painful skin lesions and rashes on the genitals, buttocks, or abdomen, which can be mistaken for eczema or psoriasis, and treatment may last up to 12 weeks.
Health officials advise anyone with symptoms to seek medical care and recommend avoiding sexual or skin-to-skin contact if infected, as
