Overview of the Outbreak
Minnesota is currently experiencing the largest known outbreak of trichophyton mentagrophytes genotype VII (TMVII), a sexually transmitted fungal skin infection commonly referred to as ringworm. The Minnesota Department of Health has reported over 30 confirmed or suspected cases since July 2025, primarily concentrated in the Twin Cities metropolitan area. This outbreak follows the first reported case in New York City in June 2024, with TMVII also noted in sporadic cases across other major U.S. cities.
Symptoms and Transmission
TMVII is characterized by painful, itchy, red, coin-like rashes that can appear on various parts of the body, including the genitals, arms, and legs. These rashes may develop into lesions or open sores, increasing the risk of secondary bacterial infections. The infection spreads through skin-to-skin contact and exposure to fungal spores, particularly during sexual activity. Health officials have emphasized that TMVII is the only known sexually transmitted fungal infection, distinguishing it from other fungal infections like T. mentagrophytes and T. interdigitale.
Treatment and Prevention
Diagnosing TMVII requires advanced testing, which can be challenging as many laboratories struggle to differentiate it from similar infections. Treatment typically involves a lengthy regimen of oral antifungal medications, lasting several weeks to months. Health officials advise against the use of steroid creams, as they can exacerbate the infection. To mitigate the risk of transmission, individuals are encouraged to avoid sexual contact if they or their partners exhibit any new rashes, and to refrain from sharing personal items such as clothing and towels.
At-Risk Populations
The outbreak has disproportionately affected men who have sex with men (MSM), as well as individuals using anonymous dating apps and those with a history of sexually transmitted infections. While the overall public health risk is considered low, state health officials have highlighted the need for increased awareness and preventive measures within these communities.
Official Statements & Responses
The Minnesota Department of Health has been proactive in addressing the outbreak, urging those diagnosed with TMVII to inform their sexual partners and avoid skin-to-skin contact until treatment is complete. They have also provided guidelines for personal hygiene and care to prevent further spread of the infection.
Criticism & Opposition
Some health experts have raised concerns about the potential for stigma associated with TMVII, particularly given its prevalence among MSM. They argue that public health messaging should focus on education and prevention rather than inadvertently marginalizing affected communities.
