title: Data from the article &amp;amp;ldquo;An opportunistic survey reveals an unexpected coronavirus diversity hotspot in North America&amp;amp;rdquo;

description: In summer 2020, SARS-CoV-2 was detected on mink farms in Utah. An interagency One Health response was initiated to assess the extent of the outbreak and included sampling animals from or near affected mink farms and testing them for SARS-CoV-2 and non-SARS coronaviruses. Among the 365 animals sampled, including domestic cats, mink, rodents, raccoons, and skunks, 261 (72%) of the animals harbored at least one coronavirus at the time. Among the samples which could be further characterized, 126 alphacoronaviruses and 88 betacoronaviruses (including 74 detections of SARS-CoV-2) were identified. Moreover, at least 10% (n=27) of the corona-virus-positive animals were found to be co-infected with more than one coronavirus. Our findings indicate an unexpectedly high prevalence of coronavirus among the domestic and wild animals tested on mink farms and raise the possibility that commercial animal husbandry operations could be potential hot spots for future trans-species viral spillover and the emergence of new pandemic coronaviruses. Figure 1. Phylogenetic relationships of the identified coronaviruses from mink and other animals from mink farms in Utah. The four genera of coronaviruses are highlighted in different colors. AlphaCoV, alkphacoronavirus; BetaCoV, betacoronavirus; DeltaCoV, deltacoronaviruses; and GammaCoV, gammacoronavirus. Type species for the currently recognized subgenera are annotated according to the nomenclature scheme used in this manuscript with the addition of the ICTV subgenus. Additional viruses, including the closest GenBank entry as identified by the BLAST tool, were included to help delineate relationship. Red circles are viruses identified in this study. Panel A. Full phylogenetic tree (A full-size image is included in Supplementary Figure 1). Red arrows designate the group of nearly identical Utah mink coronavirus strains collapsed into the colored triangle in Panel B. Table 1. Coronavirus distribution among species tested. The species are listed by their common names; Total, the total number of animals of each species tested; Negative, number of each species with no coronavirus detected among the tissues tested; Positive, number of animals positive for coronavirus in at least one tissue; % Pos, percentage of coronavirus positives in each species.
