Emerging Fungal Skin Infection Linked to Sexual Transmission in New York City

Health experts have identified a new sexually transmitted fungal infection in New York City, marking the first case of its kind in the United States. The infection, known as Trichophyton mentagrophytes type VII (TMVII), was detected in a man in his 30s who developed ringworm on his penis, buttocks, and limbs. Cases of TMVII have been increasing in Europe, particularly among men who have sex with men. The infected individual had a history of traveling to England, Greece, and California, engaging in sexual activities with partners who did not exhibit similar symptoms. Physicians are advised to inquire directly about genital rashes in sexually active patients, especially those with recent travel history and itchy skin elsewhere on the body.

Trichophyton indotineae, another fungal skin infection prevalent in India and recently identified in the US, poses challenges in treatment. Standard antifungal therapies like terbinafine may not be effective against this strain, leading to prolonged infections. Research conducted on patients with Trichophyton indotineae revealed resistance to terbinafine, prompting the use of itraconazole with improved outcomes. However, itraconazole usage comes with side effects such as nausea and diarrhea, necessitating careful monitoring. While cases of TMVII and Trichophyton indotineae in the US are currently low, dermatologists are urged to remain vigilant and adaptable in their treatment approaches. Ongoing studies aim to enhance understanding of these fungal infections and optimize patient care.
