This news item from Horse Magazine is about: When a horse spikes a fever without the nasal discharge, coughing, and other respiratory signs you’d expect to see with an infectious disease, the potential causes could be vast. In the Great Lakes region and eastern United States, which are the areas known to have the highest tick-borne-disease incidence in both human and animals, one suspect is tick-borne disease. To find out how prevalent tick-related fevers are in horses, Linda Mittel, MSPH, DVM, senior extension associate at Cornell University’s College of Veterinary Medicine, in Ithaca, New York, studied causes of fever of unknown origin (FUO). She presented her results at the 2018 American Association of Equine Practitioners Convention, held Dec. 1-5 in San Francisco, California.
