Dengue is spreading in Europe: how worried should we be? 

The post-COVID travel boom combined with a warm summer have led to dengue outbreaks in Italy and France. 

The resumption of international travel after the COVID19 pandemic has brought more travellers back from dengue-endemic areas. As of 27 October, France reported 1,414 imported instances of dengue; in 65% of cases, individuals had arrived from Martinique (550) and Guadeloupe (369). By contrast, only 217 imported cases were reported in 2022 and 164 in 2021.
