Abstract:
We describe an outbreak of SARS-CoV-2 on a transition unit composed of elderly patients awaiting placement. Environmental and patient sample analyses using digital droplet PCR (ddPCR) suggested possible fomite transmission and a high viral burden source from a few individual patients. This outbreak illustrates challenges inherent to this specific patient population.
