UK Families Battling Toxic Super-Fungus Spread

A once-rare genital super-fungus, known as trichophyton indotineae, is now a growing concern across the UK, with cases surging by nearly 500% in the past three years. This infection, which was first reported in India in 2014, has mutated to resist standard antifungal treatments, making it notoriously hard to eradicate.

The fungus causes itchy, red rashes primarily on the groin, thighs, and buttocks, but if left untreated, it can spread to other body parts, leading to pain, inflammation, and scarring. Experts highlight that the infection is not life-threatening but can be severely socially limiting, potentially causing individuals to feel ashamed and become 'social pariahs'. Diagnosis can also be challenging, as it may be mistaken for eczema or psoriasis.

Recent data presented at a conference in Poland revealed a sharp increase in infections in the UK and Ireland, rising from 44 before 2022 to 258 by March 2025. The fungus spreads easily within families through contaminated items like towels and clothing, and previous reports have linked it to sexual contact. While most reported cases in the UK are among people of South Asian heritage, experts predict it will spread to the wider population soon.
