Epidemiological studies

Published 20 April 2020 | Updated 27 September 2021

There have now been a number of prevalence studies published, and reported in the news, providing details of levels of infection with SARS-CoV-2 in companion animals. In interpreting and comparing the results of these studies is important to be clear about what population of animals is being sampled, general population or those owned by people with confirmed COVID-19 infection and which tests are being carried out (antigen or antibody).

On 20th March, IDEXX Laboratories reported1 that they had tested thousands of canine and feline specimens during validation of a new veterinary test system for the COVID-19. The samples originated from the United States and South Korea, and IDEXX has now expanded monitoring to Canada and European countries and has seen no positive results in pets to date.

Although they state that sampling included areas with high rates of COVID-19 in the human population, details of the sampling strategy and timing were not given.
