Newly Emerged Sexually Transmitted Fungal Infections: Trichophyton mentagrophytes type VII and Trichophyton indotineae - Unresponsive to Standard Therapies

Experts are warning healthcare providers and the public about the emergence of new and highly contagious forms of ringworm or jock itch in the United States. These fungal infections, which can take months to clear up even with treatment, have been identified as Trichophyton mentagrophytes type VII (TMVII) and Trichophyton indotineae. The first reported case of TMVII was documented in an NYC man who had traveled to Europe and California and had multiple male sex partners. This sexually transmitted infection has also been on the rise in Europe, particularly among men who have sex with men.

The New York State Department of Health is partnering with NYU Langone Health to investigate the largest group of patients in the country with this fungal strain that resists standard therapies. Both TMVII and Trichophyton indotineae often cause skin rashes, or tinea, and can be confused with lesions caused by eczema.

Healthcare providers should ask about rashes around the groin and buttocks for sexually active individuals who have recently traveled abroad. It is important to note that these infections may not respond to standard antifungal therapies such as terbinafine, and alternative treatments like itraconazole may be necessary.

While US rates of these fungal infections remain low, healthcare providers should stay informed about their signs and symptoms to ensure proper diagnosis and treatment. It is also crucial for individuals to practice good hygiene and avoid close contact with infected individuals to prevent the spread of these contagious fungi.

  • Unique Points
    • An NYC man in his 30s is the first reported case of a sexually transmitted form of ringworm called Trichophyton mentagrophytes type VII (TMVII) in the US.
    • The man had traveled to England, Greece and California before developing a rash on his penis, buttocks and limbs.
    • Healthcare providers should ask about rashes around the groin and buttocks for sexually active individuals who have recently traveled abroad.
  • Accuracy
    • The tinea explored in the new reports can look very different from the neat, regular circles seen in most forms of ringworm and may be confused for lesions caused by eczema.
    • Trichophyton mentagrophytes type VII (TMVII), the sexually transmitted form of ringworm, has been increasingly diagnosed throughout Europe with 13 instances reported in France in 2023.
    • Patients are often reluctant to discuss genital problems, so physicians need to directly ask about rashes around the groin and buttocks, especially for those who are sexually active, have recently traveled abroad, and report itchy areas elsewhere on the body.
    • Cases of the fungus are rare in the US, but people experiencing itchy eruptions in areas like the groin and buttocks should see a doctor.

  • Fallacies (95%)
    No formal fallacies found. However, there are some inflammatory rhetorical elements and a potential appeal to authority. The author uses phrases like 'highly contagious fungal strains', 'first reported case in the US', and 'on the rise in Europe, especially in men who have sex with men' to create a sense of urgency and fear around the topic. Additionally, there is an appeal to authority from Dr. Avrom S. Caplan and Dr. John G. Zampella, which provides credibility to the claims made in the article.
    • Health experts are warning of new and highly contagious fungal strains after an NYC man in his 30s developed a sexually transmitted form of ringworm — the first reported case in the US.

    • A man in his 30s who developed tinea (ringworm) after traveling to Europe and California, and having multiple male sex partners was diagnosed with Trichophyton mentagrophytes type VII (TMVII), a sexually transmitted fungus.

    • TMVII rashes may be confused with lesions caused by eczema, which can delay treatment.
    • Standard antifungal therapies such as terbinafine may not clear up TMVII infections, but itraconazole has shown better results.
    • Trichophyton indotineae, another contagious skin infection that causes similar rashes, often resists terbinafine treatment and can be a greater challenge for dermatologists.
