Medical records and state vital statistics data were linked to ascertain death. Multivariable survival analysis estimated the association between recent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (a positive SARS-CoV-2 test of \u226430 days before incident culture) and mortality among SAB cases, adjusting for other risk factors. Analyses were stratified by MRSA\/MSSA and epidemiologic class (hospital-onset [HO], healthcare-associated community-onset [HACO], and community-associated [CA]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Overall, SAB mortality was 21%. Annual SAB mortality rates were generally stable prepandemic before increasing by 33% and 41% among HO MRSA and MSSA cases, respectively, and by 49% among CA MRSA cases, but not among HACO or MSSA CA cases, from 2019 through 2021. Among HO cases with recent SARS-CoV-2 infection, annual mortality rates were as high as 75%. Adjusted hazard ratios for recent SARS-CoV-2 infection ranged from 1.9 (95% confidence interval: 1.5\u20132.3) (HACO MRSA) to 3.0 (95% confidence interval: 2.4\u20133.7) (HO MSSA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Recent SARS-CoV-2 infection was a significant risk factor for death among patients with SAB during 2020\u20132022.
