Emerging, vector-borne diseases in a changing European environment Renaud Lancelot (CIRAD) and Guy Hendrickx (Avia-GIS) EDEN Importance of vector-borne diseases Vector-borne diseases are a significant part of emerging infectious diseases and their relative importance is increasing They are highly sensitive to local and global environmental changes: • Climate change • Intensification of commercial exchanges and international travels • Land-cover and land-use changes • Socio-economic changes 14% 29% 12% 28% 40% 45% Jones et al., 2008. Global trends in emerging infectious diseases. Nature, 451 : 990-993. http://dx.doi.org/10.1038/nature06536 EDEN call (2004) The aim is to identify, evaluate and catalogue European ecosystems and environmental conditions linked to global change, which can influence the spatial and temporal distribution and dynamics of pathogenic agents. A coordinated European approach is needed to provide predictive emergence and spread models including global and regional prevention, early warning, surveillance, and monitoring tools and scenarios. Coordination with international organizations and third-world countries is essential. EDEN integrated project • 24 countries, • 49 partners, • 80 scientific teams, • 120 field sites, • 60 PhD Students, • 200 research years EDEN integrated project 49 24 Data Management & Information Systems (WP6.1) Low Resolution Remote Sensing & Spatial Modelling (WP6.2) High Resolution Remote Sensing & Environmental Change Monitoring (WP6.2) Mathematical Modelling & Disease Establishment and Spread (WP6.3) Africa WNV-RVF Malaria West Nile Leishmania - grouped under WP6 - Rodent Borne Horizontal Integration Teams Tick Borne Vertical Disease Sub-Projects For each indicator disease, field studies are conducted to understand patterns and processes: WP1 – Landscapes/biotopes WP2 – Vectors WP3 – Public health WP4 – Animal hosts/reservoirs WP5 – Integrated data analysis Biodiversity & Impact on Disease Spread (WP6.3) WP8 Training, Dissemination, Management & Coordination Tools and Scenarios - WP7 - EDEN findings A key outcome of EDEN is that many of currently observed changes in disease occurrence are driven by complex multifactorial causes and can often not simply be linked to a single cause. Socio-economic factors affecting behavior and contacts between hosts, vectors and pathogens often appear to be more important drivers of change than climatic factors. This complexity should not be overlooked in disease risk studies and public health policy making. e.g. Tick-borne encephalitis Conceptual model and empirical evidence of causes of spatio-temporal heterogeneity in TBE epidemiology in Central and Eastern Europe (Sumilo D, Asokliene L, Bormane A, Vasilenko V, Golovljova I, Randolph S 2007. PloS ONE, 2: e500) EDEN next One of the main EDEN assets is to have generated a pan-EU network of experts, including an extensive PhD network, in research on vectors and vectorborne diseases = VBD past-present-future. The EDEN network is now considered by publichealth agencies as ‘incontournable’ on the topic of vector-borne diseases. This already yielded spin-off projects with ECDC and ESA. The EDEN consortium will also coordinate replies to upcoming FP7 calls.
