We report that Aedes albopictus Paris collected in June 2023 were experimentally able to transmit at least three dengue virus (DENV) serotypes, from 14 days post-infection (dpi) for DENV-3 and DENV-4, and from 21 dpi for DENV-2. Given the growing number of dengue autochthonous cases reported in France, episodes of active transmission in Paris are expected as it was reported in 2023 in the greater Paris area.
