Health experts are cautioning that a highly contagious fungal skin infection is likely already spreading in the United Kingdom.
Instances of Trichophyton mentagrophytes genotype VII (TMVII), a sexually transmitted fungal infection known to cause severe ringworm (tinea), may be present in the UK. Confirmed cases have been reported across Europe and over 30 confirmed or suspected cases in Minnesota, where the largest outbreak in the US is currently happening.
The infection spreads through skin-to-skin contact or exposure to fungal spores and typically necessitates weeks to months of oral antifungal medications, as outlined by the American Academy of Dermatology.
Symptoms include ringworm on various body parts like arms, buttocks, genitals, and legs, manifesting as circular, coin-like red and irritated rashes with possible bumps and pimples on the surface, as stated by the Minnesota Department of Health. These rashes can be painful, leading to scarring and, in severe cases, more serious infections.
TMVII is thought to be as contagious as other skin fungi, easily transmissible between individuals. It is recognized as the sole known sexually transmitted infection caused by a fungus, according to the Cleveland Clinic.
The first documented case of TMVII was reported in New York City in June 2024, involving a man in his thirties who developed a persistent rash following sexual encounters with multiple men during his travels to England, Greece, and California, as reported by the Mirror US.
Minnesota is facing the largest known outbreak of TMVII in the US, with over 30 confirmed or suspected cases since July, according to the Minnesota Department of Health.
Experts have also highlighted the presence of TMVII in Europe, with cases linked to sexual activities or exposure in fitness clubs, as indicated in research cited by the National Library of Medicine.
Dr. David Denning, an infectious diseases specialist at the University of Manchester, expressed concerns that there may be undetected cases of TMVII in the UK, especially in the early stages.
He further mentioned, “It is probable that individuals with early symptoms might not seek immediate treatment, potentially leading to unintentional transmission to others through close contact. Although not more transmissible than other skin fungi, it can cause severe inflammation resulting in treatment resistance. Previous cases have been reported in countries like France, Germany, Canada, as well as in the Middle East in cities like Dubai and Abu Dhabi.”
Dr. Neil Stone, a consultant in infectious diseases and microbiology at University College London Hospitals, emphasized the need for global awareness and proactive measures by healthcare professionals to identify, test, and treat TMVII cases effectively.
He added, “There is a pressing need for increased research into the diagnosis and management of these emerging infections. Fungal infections have historically been overlooked, limiting treatment options available.”
