Notes from the Field: Recurrence of a Multistate Outbreak of Salmonella Typhimurium Infections Linked to Contact with Hedgehogs — United States and Canada 2020

摘要

In July 2020, PulseNet, the national molecular subtyping network for enteric disease surveillance, detected a cluster of 17 Salmonella Typhimurium infections. The isolates were closely related genetically to each other (four allele differences) by whole genome sequencing (WGS) analysis and related to isolates from two previous outbreaks of S. Typhimurium infections linked to pet hedgehogs (1,2). An investigation was initiated to characterize illnesses and identify the outbreak source.
