There is evidence animal-to-human spread of the coronavirus is not possible, according to medical professionals.


Horse owners still have concerns about the coronavirus, however, and answers are not readily available.


The Centers for Disease Control and Prevention said there are many types of human coronaviruses. These include some that commonly cause mild upper-respiratory tract illnesses.


Of concern now is COVID-19, which is caused by the novel coronavirus SARS-CoV-2.


Equine veterinarians emphasize equine-enteric coronavirus and COVID-19 are not the same strain. Veterinarians said there is no indication that either is transmissible between species.


Equine veterinarian Nathan Slovis said the coronavirus strain in horses caused gastrointestinal illness.


One research trial found 27% of healthy foals and 29% of diseased foals had the coronavirus in their manure.


"Relevant to present conditions there are no cases of respiratory illness associated with the equine strain in humans," Slovis said. "Therefore, we can infer that horses infected with the coronavirus will not spread it to humans."


CDC officials said no evidence of COVID-19 horse-human spread has been reported. However, some dogs and cats have been infected by COVID-19 after close contact with people infected with COVID-19. As of April 22, there is no evidence that pets can spread the virus to people, the CDC reports.


There is no evidence that equine-enteric coronavirus poses a threat to humans or other animal species, CDC officials said.


Equine coronavirus is transmitted between horses when manure from an infected horse is ingested by another horse. It can be transmitted if a horse makes oral contact with items or surfaces that have been contaminated with infected manure.


Typically mild clinical signs include anorexia, lethargy, fever, colic or diarrhea.


Veterinarians diagnose equine-enteric coronavirus by testing fecal samples.


While frequency of this disease is low, when diagnosed, treatment includes fluid therapy and anti-inflammatories.


Biosecurity precautions quarantining the infected horse are necessary while keeping facilities as clean as possible.


Disposal of manure will help decrease the chances of horses contracting the virus.


As authorities take action to mitigate the spread of COVID-19, every horse activity also is being impacted.


Locally and nationwide rodeos, jackpot events, horse shows, clinics, fairs and more are being canceled or postponed.


The iconic Kentucky Derby has been postponed to September, Kenneland has canceled its spring meet and live racing is canceled at Belmont.


However, a Kent, Ohio, assisted living community invited horses this past Friday in hopes of bringing smiles to its residents.


Kentridge Assisted Living has had to restrict visitors to only staff. On Friday, the residents had a different view from their windows.


Horses from the Happy Trains Farm and Animal Sanctuary paraded past their windows, visiting through the glass.


"I want to see my residents amazed. I want to see them smiling. I want to see them just beaming from ear to ear," said John McAninch, Kentridge executive director. "We have to think outside the box. We have to find ways to keep the residents engaged. We are in new times so we are going to keep working on things like this."


CDC officials advised horse owners and all others to strictly observe social distancing restrictions, hand-washing and other infection-control measures.
