Solid organ transplant recipients are at increased risk of COVID-19 associated morbidity and mortality. We describe the first nosocomial outbreak investigation on an immunocompromised inpatient unit aided by SARS-CoV-2 whole genome sequencing. Two patients were identified as potential index cases; one presented with diarrhea and the other tested positive on hospital day 18 after developing hypoxemia and subsequently testing positive for SARS-CoV-2. Following identification of the SARS-CoV-2 cluster, the unit was closed to new admissions, and the remaining patients and staff members underwent surveillance SARS-CoV-2 testing. Four additional patients and four staff members tested positive for SARS-CoV-2. Asymptomatic patients with COVID-19 were treated with bamlanivimab and all were alive at discharge. The unit was then re-opened with no additional positives reported since the initial outbreak. Preventing SARS-CoV-2 outbreaks in transplant units poses unique challenges as patients may have atypical presentations of COVID-19. Immunocompromised patients who test positive for SARS-CoV-2 while asymptomatic may benefit from monoclonal antibody therapy to prevent disease progression. All hospital staff members working with immunocompromised patients should be promptly encouraged to receive SARS-CoV-2 vaccination. This article is protected by copyright. All rights reserved.
