Figure 4

Posterior estimates of disease freedom varied based on prior input and the number of samples collected from each species in March 2023 in study of SARS-CoV-2 and influenza A viruses in wild mammals, United States. Collecting larger sample sizes enabled posterior estimates to depend less on prior inputs. The probability of disease freedom was analyzed for SARS-CoV-2–negative swabs from each species within each site. Probabilities for 8 species at a site in Iowa, United States, are shown.
