Cluster of human dermatophilosis in Men Who Have Sex with Men in Lyon and Paris, France, 2025–2026
We report a genomically linked cluster of nine Dermatophilus congolensis cutaneous infections diagnosed within two months among men who have sex with men in Lyon and Paris, France (2025–2026). Genomic similarity and shared sexual exposures strongly suggest interhuman sexual transmission of this zoonotic bacterium.
