👉 Ontario infection, also known as Ontario virus or Ontario virus disease, is a rare viral illness primarily affecting horses in Ontario, Canada. It is caused by the Parvovirus B19, which belongs to the parvovirus family. This virus typically causes mild infections in healthy horses, but in some cases, it can lead to more severe complications, particularly in young horses and those with weakened immune systems. Symptoms include fever, lethargy, anemia, and in severe instances, jaundice and death, especially in foals. The virus spreads through direct contact with infected bodily fluids or contaminated environments. While most infections are asymptomatic or mild, Ontario infection can be serious, necessitating veterinary intervention to manage symptoms and prevent complications.
