Hospital-acquired (nosocomial) COVID-19 transmission was associated with higher rates of 30-day mortality and more severe disease during the early phases of the pandemic, but the risk has lessened in the post-Omicron landscape, according to a new study from JAMA Network Open based on outcomes seen in Sweden during the past 3 years.
