This talk will begin by briefly discussing animal health surveillance in Canada and the role of the Canadian Animal Health Surveillance System (CAHSS). CAHSS is a distinct division of Animal Health Canada and uses a network of network approach to bring together and use data-driven information to demonstrate animal health, minimize impacts of disease, and guide planning on national animal health priorities. This system was put to the test following the detection of Highly Pathogenic Avian Influenza A(H5N1) clade 2.3.4.4b, genotype B3.13 in dairy cattle in the United states which widely and rapidly spread across the country and continues to cause problems. To date the US has reported 296 affected herds with frequent spill over into poultry operations resulting in the depopulation of around 17.6 million birds. The US Center for Disease Control has also reported 14 human cases, mostly among dairy and poultry workers. However, they have also reported one human case in Missouri with no known animal exposure and illnesses among other close contacts. This outbreak has been unprecedented and unexpected and remains difficult to control in the US. Fortunately, Canada has found success driven by a multi-stakeholder collaborative approach which we hope to continue to leverage in preparing for outbreaks in our animal agricultural sectors.
