5.C. Scientific session: Strengthen resilience against emerging vector-borne diseases through the ECDC Fellowship Programmes

Abstract Over the past decade, climate change has impacted the transmission of a wide range of vector-borne diseases (VBDs) in Europe, where locally transmitted outbreaks have occurred. It has been implicated in the observed expansion of competent disease vectors in Europe such as Aedes albopictus, which transmits diseases such as Zika, Dengue and Chikungunya. Climate may influence the life cycle of vectors, and the reproduction rate of viral particles inside vectors and human hosts, which means that upsurges in temperature can reduce the incubation period of these pathogens and the life cycle of vectors, thus boosting transmission risk through elevated vector populations. Moreover, globalization and international air travel contribute to pathogen and vector dispersion internationally. Risk mapping suggests further expansion of the species in northern Europe due to climate change. The above underscores the necessity for more proactive measures, such as developing an effective vector control program by monitoring the density and distribution of hosts and pathogens at urban, national, and cross-border levels. Additionally, establishing early warning systems based on integrated human and zoonotic and entomological surveillance is crucial to detect alerts promptly and comprehend where and when infections may emerge or spread. Furthermore, cross-border collaboration and harmonization of vector-borne surveillance systems across European countries may improve preparedness, control and response to mosquito-borne diseases. Preparedness and response require significant efforts from EU Member States and neighbouring countries. Only through a multidisciplinary approach, involving multiple sectors, can we truly prepare to address public health threats. To contribute to strengthening resilience against cross-border public health and emerging health threats in EU Member States and neighbouring countries, the European Centre of Disease Prevention and Control (ECDC) has established three fellowship training programmes. These programmes aim to create and maintain a network of highly qualified epidemiologists, microbiologists and public health professionals and strengthen the public health epidemiology workforce at EU and neighbor countries. This workshop will offer attendees a comprehensive overview of the ECDC’s fellowship programmes, describe how they function and explain their role in preparing for health threats. It will provide examples of three projects carried out by fellows on the implementation of preparedness, response and control measures for emerging vector-borne diseases in European countries at local, national and multinational levels. Those will set the scene for an in-depth analysis of the key challenges faced and can help promote awareness that integrated, multidisciplinary interventions are both feasible and effective in reducing the threat of vector-borne infectious diseases spreading in Europe and neighboring countries. Key messages • ECDC fellowship programmes aim to strengthen resilience against emerging public health threats in EU Member States and neighboring countries. • Fellows are engaged in national and cross-border integrated and multidisciplinary interventions to strengthen preparedness and mitigate the spread of emerging vector-borne diseases.
