We examine a large severe acute respiratory syndrome coronavirus 2 outbreak in a Catalan penitentiary center in February\u2013April 2021, prior to vaccination deployment. The aim was to describe the evolution of the outbreak using classical and genomic epidemiology and the containment strategy applied. The outbreak was initially detected in 1 module but spread to 4, infecting 7 staff members and 140 incarcerated individuals, 6 of whom were hospitalized (4.4%). Genomic analysis confirmed a single origin (B.1.1.7). Contact tracing identified transmission vectors between modules and prevented further viral spread. In future similar scenarios, the control strategy described here may help limit transmission of airborne infections in correctional settings.<\/jats:p>","DOI":"10.1093\/infdis\/jiae161","type":"journal-article","created":{"date-parts":[[2024,4,4]],"date-time":"2024-04-04T03:16:50Z","timestamp":1712200610000},"page":"374-381","source":"Crossref","is-referenced-by-count":3,"title":["Analysis
