Trichophyton mentagrophytes type VII is a fungal species that are usually transmitted through environmental spores. This fungal infection normally causes skin issues in animals. But wait – there’s more. Trichophyton mentagrophytes type VII can also affect humans. And it’s spread through sexual contact, leading to a fungal STI that causes drug-resistant, difficult-to-treat genital ringworm (“tinea genitalis”). I’m sure you don’t want this fungus among us. However, at least one case of Trichophyton mentagrophytes type VII infection was reported in New York City.
According to EmilyAnn Jackson’s reporting, the rare fungal STI appeared in a man in his 30s after a period of travel. The man enjoyed his time in Greece, England, and California. During the trip, he engaged in sexual contact with various different men. A study published by the CDC (and unrelated to this specific case) suggests that Trichophyton mentagrophytes type VII infection could be more common in men who have sex with men (MSM).
A Case Study: Contracting and Treating a Rare Fungal STI
After the man returned home, he noticed something concerning: an itchy rash began to spread across his legs, buttocks, and groin. The itchiness increased; the rash became increasingly flaky, red, and irritated. Eventually, the man couldn’t wait any longer. He sought out a doctor.
An observational case study published in JAMA Neurology shares that tests came back positive for Trichophyton mentagrophytes type VII. Other forms of Trichophyton fungus have been observed in the US, including a Trichophyton indotineae infection in an immunocompromised woman in Philadelphia. But the man’s case is the first time Trichophyton mentagrophytes type VII specifically was identified within the country.
There is a positive: this fungal STI is treatable (although treatment is often long-lasting). In this case, the man was treated with oral anti-fungal medication for 18 weeks (approximately 4.25 months).
Doctors want to stress that Trichophyton mentagrophytes type VII is likely nothing to panic about. This infection is uncomfortable, but not deadly. And, given the uniqueness of this case, there remain no outbreaks of this infection across the US. However, doctors also note that if you observe an itchy rash in your groin area, or lesions you believe look like ringworm, you should speak to a professional as soon as possible.
