Health experts are raising awareness about a little-known infection called Trichophyton mentagrophytes genotype VII, or TMVII, a fungal disease that can spread through sexual contact. Doctors say the infection has been increasingly reported in recent years, particularly among men who have sex with men (MSM). Although it is treatable, TMVII can cause painful skin lesions and may be mistaken for other skin conditions, delaying diagnosis and treatment.

TMVII is part of a group of fungi called dermatophytes, which cause infections commonly known as ringworm. Despite the name, ringworm is not caused by worms but by fungi that infect skin, hair, or nails.

Understanding what TMVII is, how it spreads, and how it’s treated can help people recognize symptoms early and seek medical care.

What is TMVII?

TMVII (Trichophyton mentagrophytes genotype VII) is a recently recognized fungal infection that can cause a type of ringworm affecting the skin. It produces red, irritated rashes that may appear on the genitals, buttocks, face, thighs, or other parts of the body. Read more here.

Health officials say the infection has circulated in parts of Europe for several years and has recently been detected in the United States. Public health researchers have noted that many early cases occurred among men who have sex with men, though the infection itself is not limited to any specific group.

Although TMVII is sometimes described as a sexually transmitted infection (STI), experts emphasize that the fungus spreads through direct skin contact, which means it can theoretically infect anyone exposed to it.

How Is TMVII Transmitted?

TMVII spreads primarily through skin-to-skin contact with an infected person, including during sexual activity. Because the rash often appears around the genitals or buttocks, intimate contact makes transmission more likely.

However, sexual activity is not the only way it spreads. The fungus can also be transmitted through contaminated items such as:

  • Towels
  • Bedding
  • Clothing
  • Sex toys
  • Razors or personal hygiene items

If these items come into contact with infected skin and are shared without proper cleaning, the fungal spores can spread to others.

What Are the Symptoms of TMVII?

TMVII infections usually appear as skin rashes that resemble ringworm. The symptoms may develop days or weeks after exposure and can vary in severity.

Common symptoms include:

  • Red or circular rash on the skin
  • Itching or burning
  • Painful or inflamed patches
  • Scaly or raised borders
  • Blisters, bumps, or pimples on the rash

These lesions often appear on the face, genitals, buttocks, trunk, arms, and legs, but they can spread to other parts of the body.

Because the rash can resemble eczema, psoriasis, or other skin infections, people sometimes delay seeking medical help. This can allow the infection to spread or worsen. (Yahoo News)

In some cases, TMVII can lead to complications such as secondary bacterial infections or scarring if untreated. Read here for more.

How Is TMVII Treated?

TMVII infections are usually treated with antifungal medications. In many cases, doctors prescribe oral antifungal drugs, since topical creams alone may not fully eliminate the infection, CDC reports. Treatment typically lasts several weeks, and some patients may require up to 12 weeks of medication before the infection completely clears.

Doctors also recommend additional steps to prevent spreading the fungus, including:

  • Avoiding skin-to-skin contact until treatment is complete
  • Informing sexual partners
  • Washing clothing, towels, and bedding at high temperatures
  • Avoiding shared personal items

Early diagnosis is important because untreated infections can persist and spread to others.

Why Awareness Matters

While TMVII is still considered relatively uncommon, health authorities are encouraging clinicians and the public to be aware of it. Early recognition can help reduce transmission and ensure patients receive proper treatment.

Anyone who notices unexplained rashes, especially around the genitals or buttocks, should consider seeking medical advice.
