Figure 1

Geographic locations of human Salmonella Typhimurium cases in the United States, 2020–2021. Colored shading indicates number of cases by state; black bird icons indicate states that detected the outbreak strain of Salmonella Typhimurium from wild birds (within 0–12 allele differences based on core genome multilocus sequence typing). One isolate was obtained from a dog’s mouth wound at a veterinary hospital in Oregon (dog icon) and matched the outbreak strain. Numbers of genetically related isolates obtained from wild birds are indicated within animal icons. Salmonella Typhimurium was also detected in wild birds as part of the Southeastern Cooperative Wildlife Disease Study at the University of Georgia (gray bird icons); those isolates were serotyped at the National Veterinary Services Laboratory (30), but whole-genome sequencing was not performed to confirm relatedness to the outbreak strain.
