What is a coronavirus?
Coronaviruses are a large family of viruses found in both humans and animals. The name is derived from the Latin word corona, or crown, since coronavirus particles have a ring of projections resembling a royal crown or solar corona. Coronaviruses can be subdivided into groups (1-4) based on microbial organization and evolution of the virus.

What are some common coronaviruses?
Canine enteric coronavirus (a group 1 coronavirus) is a highly contagious intestinal infection seen mostly in young puppies. It is spread by oral contact with infected feces and causes diarrhea that is self-limiting in adult dogs but can be more severe in young puppies. A vaccine is available. This virus is not contagious to other species.

Canine respiratory coronavirus (a group 2 coronavirus) is genetically related to the common cold in humans. It is spread by direct dog to dog contact and causes acute respiratory symptoms and contributes to canine infectious respiratory disease complex (sometimes called CIRDC or kennel cough). No vaccine is available for this respiratory virus, although there are vaccines for some of the other causes of CIRDC, such as canine influenza virus, distemper virus and Bordetella.

Feline Infectious Peritonitis (FIP) is caused by a mutation in the otherwise innocuous feline enteric coronavirus. Due to this mutation and/or an alteration in the cat’s immune system, white blood cells become infected with the virus and create an intense inflammatory reaction throughout the body. This disease is almost always fatal. A minimally effective vaccine is available. Feline enteric coronavirus is not the same as canine enteric coronavirus and neither disease is contagious to the other species.

SARS-CoV (severe acute respiratory syndrome coronavirus) was first recognized in China in 2002. This virus is believed to have originated in bats before it was transmitted to civet cats and then humans. No cases have been reported worldwide since 2004.

MERS-CoV (Middle East Respiratory Syndrome Coronavirus) was first reported in Saudi Arabia in 2012. Since then all cases have been linked to countries in or near the Arabian Peninsula. This virus is believed to have originated in bats before it was transmitted to dromedary camels and then humans.

What is the 2019 Novel Coronavirus?
2019 Novel Coronavirus (2019-nCoV) is a viral infection identified as the cause of a respiratory illness outbreak first detected in Wuhan, China in 2019. Early on, many patients had some link to a large seafood and live animal market in the area, suggesting animal-to-person spread. Later, a growing number of patients reportedly did not have exposure to animal markets, indicating person-to-person spread. This virus causes symptoms of fever, cough, and shortness of breath in varying intensity.

The first infection with 2019-nCoV in the United States was reported on January 21, 2020. The Centers for Disease Control and Prevention (CDC) is closely monitoring the situation and working to prevent sustained spread of 2019-nCoV in the United States.

Can dogs (or other pets) contract 2019-nCoV?
At this time, health officials have expressed no concern about transmission to or from companion animals.

Can I contract 2019-nCoV from my pet?
Both the Centers for Disease Control (CDC) and World Health Organization (WHO) report that there is no evidence that companion animals such as pet dogs or cats can spread 2019-nCoV.

Can I travel with my pets or import pets from regions where cases of 2019-nCoV are reported?
The CDC notes that this situation is evolving and potential travelers are encouraged to monitor travel health notices available at

The United States Department of Agriculture Animal and Plant Health Inspection Service oversees international pet travel. While no specific warnings or recommendations have been issued regarding pet travel, you should consult with your local and state veterinarians about any potential risk associated with international travel.

What can I do to keep myself and my pets safe from infectious disease?

  • Wash hands often with soap and water for at least 20 seconds or use an alcohol-based hand sanitizer.
  • Avoid close contact with people who are sick and stay home when you are sick.
  • Isolate (keep separate) dogs that have been exposed to an animal with respiratory or intestinal illness, and those currently showing signs such as coughing, sneezing, vomiting or diarrhea. Notify your veterinarian of these signs for direction on when and how to bring your dog to the clinic for evaluation and treatment.
  • Follow your veterinarian’s recommendations for preventive care, such as heartworm and flea and tick control, vaccinations, and nutrition to keep your pet as healthy as possible.
  • Practice good hygiene and sanitation in your home and at all facilities where you and your pet visit.

Coronaviruses comprise a large family of viruses that affect humans and animals. The coronaviruses that cause diarrhea and respiratory symptoms in dogs are not the same, nor are they the same as the 2019 novel coronavirus currently in the news (February 2020). According to the World Small Animal Veterinary Association there is “no evidence that existing [coronavirus] vaccines would protect against pathogenic [disease-causing] variants of [canine coronavirus].” Both the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) report that at this time (February 2020) there is no evidence that companion animals such as pet dogs or cats can spread 2019-nCoV.
