A strain of extensively drug-resistant (XDR) Salmonella enterica serovar Typhi has caused a large ongoing outbreak in Pakistan since 2016. In Ontario, Canada, 10 cases of mainly bloodstream infections ( n = 9) were identified in patients who traveled to Pakistan. Whole-genome sequencing showed that Canadian cases were genetically related to the Pakistan outbreak strain. The appearance of XDR typhoid cases in Ontario prompted a provincial wide alert to physicians to recommend treatment with carbapenems or azithromycin in suspected typhoid cases with travel history to Pakistan.
