    The importance of ISAV HPR0 for causing clinical outbreak of ISA

    The project will develop a method for ranking of individual site risk of ISA (based on the presence of HPR0 and local spread of virulent HPR-deleted ISA virus) by determining a quantitative risk estimate for each site. Such a model will be useful both in terms of more effective and risk-based surveillance, and the possibility to implement more optimal disease prevention. Ranking of sites will be based on factors such as fallowing management, biomass density, mortality, sea temperature, distance to the slaughterhouse, others diseases, lice treatment etc. The analysis will be based on isolated ISA outbreak of 2003-2014, aquaculture data and journal data from the Norwegian Veterinary Institute and knowledge generated in subproject 1.
