​On March 8, 2017, NevadaCounty.com in California reported that two local horses in the Penn Valley area were officially diagnosed with equine Coronavirus by veterinarians. The following is reported from that government website.

Testing on other horses in the immediate contact area is underway. Equine Coronavirus is transmitted through contact with feces. There is no threat to humans, but there is significant threat to horses. The mortality rate for horses is fairly low with proper diagnosis and treatment. Isolation and monitoring, and contacting a veterinarian immediately is recommended. Equine Coronavirus is extremely contagious and limiting interactions between horses and animals outside their property is recommended. People riding on trails must be careful and people visiting other ranches or horse facilities should wash their hands and limit interactions with other animals.

Signs of Equine Coronavirus:

• lethargy
• off feed
• mopey
• dehydration
• frequently laying down 

With Equine Coronavirus, horses can go from having no fever to a high fever in a very short amount of time. Contact your veterinarian immediately if you think your horse is displaying any of these clinical signs. A veterinarian can perform a simple test on a fecal sample. 

Persons around horses can take the following protection measures:
• hand washing and avoiding contact
• changing your clothes and shoes before and after interacting with your horses
• putting together a bleach dip for your shoes at the entrance of your barn
• cleaning hoof picks, feed buckets, and farm tools with bleach on a daily basis
• placing stall waste and horse manure that could be contaminated in a separate area
• limiting interaction between your horses and outside horses until the virus has subsided, roughly 3-4 weeks You may contact the Nevada County Agricultural Commissioner Department at 530-470-2690 or agdept@co.nevada.ca.us for more information.
