We recently observed a high rate of multidrug-resistant (MDR) S. sonnei bacteremia among persons experiencing homelessness (PEH). We aim to describe the wider epidemiology, clinical outcomes, and genomics of S. sonnei infections over time. Methods A retrospective review of 163 patients with S. sonnei infections was undertaken from 2015 –2022. We collected demographic, clinical, and microbiological data over two time periods: historical (2015-2020) and recent (2021-2022). Severe shigellosis definition included hospitalization, bacteremia, or death. Whole genome sequencing was performed to identify genotype, infer relatedness, and predict antimicrobial resistance. Results S. sonnei infections rose from 8.3 (historical-period) to 56.5 cases/year (recent-period). Over time, the primary population characteristics associated with shigellosis shifted from MSM (45, 98%) to PEH (86,77%). The population intersection between MSM and PEH historically and recently was similar and occurred in three (6%) and ten (9%) of patients, respectively. Severe shigellosis was significantly higher in the recent compared to historical period (69 [61%] versus 7 [14%], p&amp;lt;0.001). A dominant clone of MDR S. sonnei, 3.6.1.1.2 (CipR.MSM5), emerged with resistance to all first and second-line agents yet with susceptibility to ceftriaxone. Conclusion We observed a substantial increase in severe shigellosis and shift from sexually transmitted S. sonnei infections in MSM to likely environmental transmission among PEH. More severe disease associated with the 3.6.1.1.2 clone of MDR S. sonnei in PEH could be a result of underlying vulnerabilities of the affected population.","PeriodicalId":10463,"journal":{"name":"Clinical Infectious Diseases","volume":"36 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared the risk of transmission among households where first cases used the Toronto Voluntary Isolation Centre (TVIC) compared to households receiving routine self-isolation guidance, prior to widespread vaccine availability. Methods Households with a first case having symptom onset between September 2020, and March 2021, that used TVIC, were propensity-score matched with up to 10 self-isolation households. Follow-up began for TVIC households on the day after check-in, or for matched self-isolation households, the equivalent delay since first case symptom onset. The outcome, 28-day secondary attack rate, was analyzed using proportional hazards models. Results 303 TVIC households were matched with 2,943 self-isolation households. Median duration from first case symptom onset to TVIC check-in was 3 days (IDR [interdecile range]=1-6 days); median check-out date was 11 days after onset (IDR=10-13 days). The attack rate among TVIC households was 5.2% (53/1,015) compared to 8.4% (787/9,408) among self-isolation households (hazard ratio [HR]=0.50, 95% confidence interval [CI]=0.28-0.90). Greater reductions were observed when first cases isolated sooner after symptom onset (HR=0.37, 95%CI: 0.13-1.04), and in larger (HR=0.30, 95%CI: 0.14-0.67) and more crowded (HR=0.34, 95%CI: 0.15-0.77) households. Conclusions Use of a voluntary isolation centre was associated with a 50% reduction in household SARS-CoV-2 attack rate, prior to the availability of vaccines. Beyond SARS-CoV-2, voluntary isolation centres may help control resurgences of other communicable infections, or future pandemic pathogens, in particular for individuals experiencing difficulties isolating.","PeriodicalId":10463,"journal":{"name":"Clinical Infectious Diseases","volume":"43 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods We developed and validated a proportional baselines landmark supermodel for TB risk prediction using health administrative data from British Columbia and Ontario, two distinct provincial healthcare systems in Canada. Demographic (age, sex, refugee status, year of entry, TB incidence in country of origin), TB exposure, and medical (HIV, kidney disease, diabetes, solid organ transplantation, cancer) covariates were used to derive and test models in British Columbia; one model was chosen for external validation in the Ontario cohort.
