Equine rabies.

This research article discusses the impact of the increase in wildlife rabies cases on horses in the United States and Canada, the difficulties in diagnosing the disease while the animal is still alive, and the importance of vaccination for animals and veterinary workers.

Increased Wildlife Rabies Cases

• The article begins by outlining the threat posed to horses due to the rising number of wildlife rabies cases across the United States and Canada.
• As the instances of rabies in wildlife grow, the likelihood of horses and other domestic animals being exposed to this life-threatening disease also goes up.

Challenges in Diagnosing Rabies

• Diagnosing rabies in horses is complicated because currently, there are no quick, definitive diagnostic tests that can be performed while the horse is alive (antemortem tests).
• The diagnosis must resort to assessing highly variable and sometimes nonspecific clinical signs that the horse may demonstrate.
• While cerebrospinal fluid (CSF) analysis can sometimes aid the diagnosis, it is not always practical in the field and may not always show abnormalities related to rabies.
• The only definitive diagnostic test— the Fluorescent Antibody Test (FAT) for detecting the rabies virus— can be carried out only after the horse has died (at necropsy).

Vaccination is Crucial

• The study emphasizes the importance of vaccinating horses with inactivated rabies vaccines, which are believed to be safe and effective.
• Horses in areas where the disease is endemic should especially be vaccinated.
• Veterinary practitioners are encouraged to communicate with state or provincial authorities to understand the necessity of vaccination in their specific areas.
• It is also vital for veterinarians, veterinary technicians, and other animal health workers to be vaccinated against rabies due to their higher risk of exposure to the disease.
