Coronaviruses are a group of viruses that infect birds and mammals, including humans. They are often associated with the common cold, bronchitis and pneumonia, and can also affect the gut. The virus that causes COVID-19 is also a coronavirus and likely originated from a wildlife reservoir.
Canine coronavirus, which can cause diarrhoea, and feline coronavirus, which can cause feline infectious peritonitis (FIP), have been seen by veterinarians for many years. They do not cause infections in humans. These coronaviruses are not associated with the current COVID-19 pandemic.
