Paul Torgerson, Sonja Hartnack, Philip Rasmussen and Violeta Muñoz presented their research at the 16th International Symposium of Veterinary Epidemiology and Economics (ISVEE) held in Halifax, Canada. Sonja presented a poster on Covid-19 diagnostic tests and how to evaluate sensitivities and specificities in the absence of a perfect gold standard. This work relates to the COST-Action Harmony. As part of the GBADs programme, Philip gave two oral presentations on the comobidity model and its applicability to assess the economic burden due to endemic diseases among dairy cattle in high-income countries. Violeta presented a poster showing preliminary results of the burden of diseases and other causes of morbidity and mortality in backyard chicken farms in low-income and middle-income countries. The ISVEE conference offered a great opportunity to acquire the latest knowledge on the field and to meet face-to-face with international experts after two years of online interactions!
