Equine influenza has been confirmed in Simcoe County, Ontario. On November 4, 2024, there was fever, coughing and nasal discharge in a group of miniature horses. Two minis were new to the property, were housed separately for two weeks but were adjacent to the resident herd's paddock. The horses are recovering. The horses were not vaccinated against equine influenza. The farm owner has instituted voluntary animal movement restrictions and is working with their veterinarian on biosecurity measures.
