We identified 2 cases of Salmonella enterica serovar Vitkin infection linked by whole-genome sequencing in infants in Ontario, Canada, during 2022. Both households of the infants reported having bearded dragons as pets. The outbreak strain was also isolated from an environmental sample collected from a patient's bearded dragon enclosure. Twelve cases were detected in the United States, and onset dates occurred during March 2021-September 2022 (isolates related to isolates from Canada within 0-9 allele differences by core-genome multilocus sequence typing). Most US patients (66.7%) were <1 year of age, and most (72.7%) had reported bearded dragon exposure. Hospitalization was reported for 5 (38.5%) of 13 patients. Traceback of bearded dragons identified at least 1 potential common supplier in Southeast Asia. Sharing rare serovar information and whole-genome sequencing data between Canada and the United States can assist in timely identification of outbreaks, including those that might not be detected through routine surveillance.

Enteric bacterial infections are common among people who travel internationally. During 2017– | 23 2020, CDC investigated 41 multistate outbreaks of nontyphoidal Salmonella and Shiga toxin24 producing Escherichia coli (STEC) linked to international travel. Resistance to one or more | 25 antimicrobial agents was detected in at least 10% of isolates in 16 of 30 (53%) nontyphoidal | 26 Salmonella outbreaks and 8 of 11 (73%) STEC outbreaks evaluated by the National | 27 Antimicrobial Resistance Monitoring System. At least 10% of the isolates in 14 nontyphoidal | 28 Salmonella outbreaks conferred resistance to one or more of the clinically significant | 29 antimicrobials used in human medicine. This report describes the epidemiology and | 30 antimicrobial resistance patterns of these travel-associated multistate outbreaks. Investigating | 31 illnesses among returned travelers and collaboration with international partners could result in | 32 implementation of public health interventions to improve hygiene practices and food safety | 33 standards, and to prevent illness and spread of multidrug resistant organisms domestically and | 34 internationally

On August 29, 2021, the United States government oversaw the emergent establishment of Operation Allies Welcome (OAW), led by the U.S. Department of Homeland Security (DHS) and implemented by the U.S. Department of Defense (DoD) and U.S. Department of State (DoS), to safely resettle U.S. citizens and Afghan nationals from Afghanistan to the United States. Evacuees were temporarily housed at several overseas locations in Europe and Asia* before being transported via military and charter flights through two U.S. international airports, and onward to eight U.S. military bases,(†) with hotel A used for isolation and quarantine of persons with or exposed to certain infectious diseases.(§) On August 30, CDC issued an Epi-X notice encouraging public health officials to maintain vigilance for measles among Afghan evacuees because of an ongoing measles outbreak in Afghanistan (25,988 clinical cases reported nationwide during January-November 2021) (1) and low routine measles vaccination coverage (66% and 43% for the first and second doses, respectively, in 2020) (2).
