In May 2022, several countries reported mpox cases from patients without history of traveling to endemic areas. France was one of the most affected European countries. In this study, we described the clinical characteristics of mpox cases in France, and studied the genetic diversity of the virus. Patients diagnosed with mpox infection (qPCR ct<28) between 21 th May and 4 th July 2022 and between 16 th August and 10 th September 2022 were included to this study. Twelve amplicons corresponding to the most polymorphic regions of the mpox genome and covering ~30,000 nucleotides were generated and sequenced using the S5 XL Ion Torrent technology to evaluate the genetic diversity of mpox sequences. One hundred and fourty-eight patients were diagnosed with mpox-infection. 95% were men, 5% transgender (M-to-F), 50% were taking HIV pre-exposure prophylaxis, and 25% were HIV seropositive. One hundred and sixty-two samples were sequenced and compared to GenBank sequences. Thirty-two distinct mutational patterns were identified. Overall, low genetic diversity of mpox sequences was found compared with pre-epidemic Western-African sequences, with 32 distinct mutational patterns. Our results provide a first glance at the mutational landscape of early mpox 2022 circulating strains in Paris (France).
