Horse 1: 
Age: 5; Gender: Mare; Breed: Quarter Horse (QH); Clinical Signs: This mare is one of several horses displaying signs of respiratory disease in the barn which range from fever, nasal discharge, mildly swollen lymph nodes and occasional cough. Horses returned from a competition a few days before the index case (a gelding) was examined for nasal discharge and slightly enlarged lymph nodes. S. equi testing was negative in the index case and the influenza-positive mare. Within the next 48-72 hours several of the horses in the barn developed similar respiratory signs. Some of the horses are vaccinated for influenza and have more mild signs.; Confirmation Date: 6/26/2024;
