Current and Past SARS-CoV-2 Infection and COVID-19 in Healthcare

Studies on Current and Past SARS-CoV-2 Infection (and COVID-19) in Healthcare in Stockholm, Sweden

The SARS-CoV-2 pandemic and resulting COVID-19 disease causes a substantial burden on healthcare systems. Little is known about how the infection spreads within healthcare.
