France reports 124 locally acquired chikungunya cases across 19 clusters; Italy one

As of September 30, 2026, France had reported 124 locally acquired chikungunya cases across 19 clusters, including 34 additional cases and six new clusters since the preceding update, and 17 French clusters were active. Italy retained one locally acquired case in Rome, with its cluster still active. The increase and the number of active clusters materially change the regional surveillance picture. These are surveillance reports, not an estimate of every infection. No map point is shown, because the clusters are spread across two countries.
