  1. aFor household and sex, p-value determined by two-sided Fisher’s exact test. Household COVID+ defined as one or more members of a household with a confirmed positive COVID-19 test. All the information was not available for all the animals. Both household (p = 0.004) and sex (p = 0.045) were associated with COVID seropositivity among dogs, whereas neither household (p = 1.000) nor sex (p = 0.492) were associated with COVID seropositivity among cats.
