Low SARS-CoV-2 seroprevalence and no active infections among dogs and cats in animal shelters with laboratory-confirmed COVID-19 human cases among employees

Human-to-animal and animal-to-animal transmission of SARS-CoV-2 has been documented;however, investigations into SARS-CoV-2 transmission in congregate animal settings are lacking. We investigated four animal shelters in the United States that had identified animals with exposure to shelter employees with laboratory-confirmed COVID-19. Of the 96 cats and dogs with specimens collected, only one dog had detectable SARS-CoV-2 neutralizing antibodies;no animal specimens had detectable viral RNA. These data indicate a low probability of human-to-animal transmission events in cats and dogs in shelter settings with early implementation of infection prevention interventions.
