Background: Regions of southern Europe are increasingly colonised by Aedes albopictus, with incidence of autochthonous dengue cases rising in recent years.AimWe describe and compare Aedes-borne disease (dengue, chikungunya and Zika) incidence from 2017 to 2023, and the surveillance systems and response measures operating in France, Italy and Portugal in 2023, to improve surveillance, prevention, preparedness and response in Europe.MethodsWe performed a benchmarking analysis to systematically capture the systems used in each country. We collected data from key-informant interviews, national guidelines, reports and scientific literature using a standardised questionnaire adapted from the European Centre for Disease Prevention and Control framework.ResultsAll three countries have an integrated surveillance system for Aedes-borne diseases and share similarities in surveillance type, geographic coverage and case definitions. Differences entail mainly event-based and active surveillance activities. Geographic coverage of vector surveillance is national in France and Portugal but regional in Italy. In response to autochthonous transmission, all countries implement/foresee active case-finding and blood safety protocols, while France and Italy strongly rely on vector control. Upon vector detection in non-colonised areas, the three countries implement ad hoc entomological surveillance and vector control.ConclusionsSurveillance systems and response measures in France, Italy and Portugal are broadly similar, with variations reflecting differences in healthcare system organisation (centralised in Portugal and France, regionalised in Italy), Ae. albopictus distribution and local transmission of Aedes-borne diseases. Risk-based surveillance, considering the national and cross-border epidemiological and entomological situations, can strengthen preparedness and early warning for Aedes-borne diseases in Europe.
Key public health message: - What did you want to address in this study and why? Different human and vector surveillance systems operate nationally to detect and report cases of Aedes-borne disease and Aedes vector presence and population dynamics in southern Europe. We aimed to describe and compare surveillance systems and response measures to Aedes-borne disease in France, Italy and Portugal to improve preparedness and response to emerging arbovirus diseases in Europe. - What have we learnt from this study? France, Italy and Portugal have integrated surveillance systems for Aedes-borne disease that share similarities in their coverage, surveillance type, disease notification and case definitions. France also operates active surveillance and Italy and Portugal event-based surveillance. The three countries implement invasive Aedes spp. surveillance in colonised areas and at points of entry. Regional variation exists due to differences in vector colonisation and health system organisation. - What are the implications of your findings for public health? Cross-border collaboration between neighbouring European countries can facilitate shared good practices in surveillance and response to Aedes-borne diseases strengthening preparedness and early warning for these diseases in Europe.
