The overall aim of the project is to develop a fully functional framework for a dynamic risk-based surveillance for vector borne diseases. The potential risk of outbreaks of vector borne diseases and consequently the spread within the population at risk will be continuously estimated. This will permit 1) active surveillance to be focused on specific periods and areas of elevated risk and 2) active surveillance activities to be fitted to the available resources at EU and national level. This framework for continuous risk based surveillance will be based on three independent pillars: (1) risk of introduction, (2) potential for spread if introduced and (3) syndrome surveillance. The proposed surveillance system will be based on computer models scanning and interpreting risk parameters already collected for other purposes (weather data, environmental data, import data, syndromes) and costs may therefore be very low.</br></br>The Norwegian Veterinary Institute main contribution within the project will be on syndromic surveillance. Syndromes in this context are events that may occur because of the disease. These events might either be reports of veterinarians of unspecified disease or mortality, but can also be registration of antibiotic use or others. The surveillance system will indicate areas and periods with unusual high numbers of such events. Bluetongue and West Nile virus will be used as examples to develop a generic framework for syndrome surveillance. Norwegian data will be analysed to identify time periods, geographical areas, or animal populations with a higher probability of having a disease, for example by cluster analyses and multivariate statistical process control.
