Question: Are my horses prone to COVID-19?

page_title: COVID-19 and Animals
section_headers: Risk of animals spreading the virus that causes COVID-19 to people
section_content: Some coronaviruses that infect animals can sometimes be spread to humans and
then spread between people, but this is rare. This is what happened with the
virus that caused the current outbreak of COVID-19. However, we do not know
the exact source of this virus. Public health officials and partners are
working hard to identify the source of COVID-19. The first infections were
linked to a live animal market, but the virus is now spreading from person to
person.
The virus that causes COVID-19 spreads mainly from person to person through
respiratory droplets from coughing, sneezing, and talking. Recent studies show
that people who are infected but do not have symptoms likely also play a role
in the spread of COVID-19. At this time, there is no evidence that animals
play a significant role in spreading the virus that causes COVID-19. Based on
the limited information available to date, the risk of animals spreading
COVID-19 to people is considered to be low.

section_headers: Risk of people spreading the virus that causes COVID-19 to pets
section_content: We are still learning about the virus that causes COVID-19, but it appears
that it can spread from people to animals in some situations.
CDC is aware of a small number of pets, including dogs and cats,
reported to be
infected with the virus that causes COVID-19, mostly after close contact with
people with COVID-19. Only a few of the pets reported to be positive showed
signs of illness.

Reviewer feedback on this answer:
Discusses only household animals and not horses
Says that some cats and dogs have been reported as infected with COVID-19, but doesn't mention horses specifically.

How can I safely run my equestrian facility?
section_content: You should follow your state and/or local jurisdictional guidance regarding
continuing operations at your facility. There have not been any reports of
horses testing positive for the virus that causes COVID-19. Based on the
limited information available to date, the risk of animals spreading the virus
that causes COVID-19 to people is considered to be low. COVID-19 is primarily
spread from person to person, so steps should be taken to reduce the risks for
people visiting your facility.

Encourage employees and other visitors, including boarders, owners, farriers, veterinarians, and those taking lessons, not to enter the facility if they are sick. Employees should not return to work until the criteria to discontinue home isolation are met, after talking with their doctor. Implement sick leave policies that are flexible, nonpunitive, and consistent with public health guidance, allowing employees to stay home if they have symptoms of respiratory infection.
Consider conducting daily health checks (e.g., symptom and/or temperature screening) of employees and others visiting the facility before they enter the premises. People with a fever of 100.40(38.00C) or above or other signs of illness should not be admitted to the premises. If implementing health checks, conduct them safely and respectfully. See General Business FAQs for more information. 
Employees or visitors who appear to have symptoms upon arrival or who become sick during their visit should immediately be separated from other employees and visitors and sent home.


Limit the number of people entering the facility. Consider staggering lesson and visiting times to limit the number of people in the facility and potential for person-to-person contact. If possible, you can also take steps to decrease high-traffic areas by limiting areas open to visitors/owners or staggering use of common areas like grooming or wash stalls and tack rooms.
Increase distance and limit duration of contact between employees and visitors in the facility. Whenever possible, people should maintain at least 6 feet of distance between each other at the facility, including instructors teaching lessons. Allow for social distancing and avoid large numbers of people within the facility, including in employee-only areas.
Visitors and employees should wear cloth face coverings to protect others especially where social distancing measures are difficult to maintain. Wearing a cloth face covering does NOT replace the need to practice social distancing.
Set up hand hygiene stations at the entrance and within the facility, so that employees and people entering can clean their hands before they enter. Employees should wash hands regularly with soap and water for at least 20 seconds. An alcohol-based hand sanitizer containing at least 60% alcohol can be used, but if hands are visibly dirty, they should be washed with soap and water before using an alcohol-based hand sanitizer. Examples of hand hygiene stations may be a hose and soap located at entrances to allow for handwashing before entry.
Clean and disinfect frequently touched surfaces such as grooming tools, halters, lead ropes, shared tack and equipment, and door handles/gates (including those to stall doors and pasture/turn out areas) on a routine basis. To disinfect, use products that meet EPA’s criteria for use against theexternal icon virus that causes COVID-19 and are appropriate for the surface, diluted household bleach solutions prepared according to the manufacturer’s label for disinfection, or alcohol solutions with at least 70% alcohol. Follow manufacturer’s directions for use, especially regarding product contact time and protections from chemical hazards posed by cleaners and disinfectants.
Follow local guidance on shelter in place and travel recommendations when traveling for showing, training, or trail riding.
If traveling to a new facility, limit contact between people, horses, tack, equipment, and other supplies from different facilities, and maintain a distance of at least 6 feet between horses and riders. 
Follow state and local guidance on travel. People who are sick should not travel to other facilities.
People visiting other facilities should follow the same precautions as they would normally, including maintaining at least 6 feet of distance between each other, wearing a cloth face covering to protect others, and washing hands frequently with soap and water.


If other animals, such as barn cats, are present at the facility, be aware that a small number of pets have been reported to be infected with the virus that causes COVID-19, mostly after contact with people with COVID-19.

Says that there haven't been any cases of horses testing positive for COVID-19, but gives general safety guidelines anyways.
a comprehensive review of how COVID19 has affeted horses and facilities. Could skip much of it to answer the question, however.
