Italy reports 59 locally acquired dengue cases across nine clusters; France six

As of September 30, 2026, Italy had reported 59 locally acquired dengue cases across nine clusters and France six across four clusters. Italy added 12 cases and two newly identified clusters from the prior week, and all nine Italian clusters were active. France added one case, and none of its four clusters remained active. These are surveillance reports submitted to ECDC, not an estimate of every infection, and the figures remain subject to testing and reporting delays. No map point is shown, because the clusters are spread across two countries.
