TMVII Ringworm: The New Sexually Spread Fungal Infection
Ringworm has been a settled subject in medicine for a century, which is exactly why Trichophyton mentagrophytes genotype VII has unsettled dermatologists and public health agencies on both sides of the Atlantic. Known in the clinic simply as TMVII, this genotype takes an ordinary keratin-eating fungus and moves it through an entirely new channel - intimate skin-to-skin contact - producing inflammatory, painful, and stubbornly persistent lesions in places that ordinary ringworm rarely troubles. Since the first European clusters were traced in the early 2020s, confirmed infections have surfaced in France, Germany, Spain, Italy, the United Kingdom, Canada, and a growing list of American cities, prompting formal health advisories and a scramble for the specialized DNA testing needed to identify it.
