Alert Issued Over Spread of Fungal Skin Infection in Minnesota
Minnesota health officials have recently raised alarms about a contagious fungal skin infection that is becoming a concern in the state. This infection is caused by a fungus known as Trichophyton mentagrophytes type VII (TMVII), which is the same fungus responsible for ringworm.
The main signs of this infection include round, red, itchy rashes that can spread across the body. These rashes can be quite irritating and painful, according to a health alert from state officials.
Dr. Hayden Andrews, an infectious disease specialist, explained that TMVII is part of a broader group of fungi that typically cause mild conditions like ringworm and athlete’s foot. He noted that the symptoms can appear similar to other common skin issues, which might lead to confusion with conditions like eczema.
The first case of TMVII in Minnesota was reported in July 2025. So far, the state has confirmed 13 additional cases, with 27 more suspected. The Centers for Disease Control and Prevention (CDC) also noted that the first U.S. case occurred in New York in 2024, with instances appearing in various cities across the country.
In response to the growing number of cases, Minnesota’s health department has put in place a system to monitor and identify new infections. Officials are concerned that the fungus could be spreading in close-knit groups, leading to larger outbreaks.
TMVII spreads through skin-to-skin contact, which can occur during sexual activity. It can also be transferred through contaminated items such as towels or surfaces, particularly in shared places like gyms and pools.
Health experts caution that certain groups are at higher risk for this infection, particularly men who engage in sexual activity with other men and sex workers. Those with a history of sexually transmitted infections may also be more vulnerable.
Diagnosis often involves examining the rash and may require tests such as skin scraping. However, doctors may start treatment based on the rash’s appearance alone, especially if over-the-counter medications are ineffective.
Dr. Andrews pointed out that this outbreak is notable for how the infection is spreading, emphasizing the need for careful monitoring and preventive measures. He warned that individuals with compromised immune systems could experience more severe symptoms and that untreated rashes may lead to complications, including scarring.
For effective prevention, health officials recommend that anyone experiencing symptoms should avoid close contact with others and refrain from sharing personal items. Thorough cleaning of linens and towels is also advised. Anyone showing symptoms should seek medical help promptly.
The health department emphasizes the importance of reporting any suspected cases for further investigation and testing.
