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

Karolinska University Hospital26,326 enrolled

Overview

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. In order to design control strategies, knowledge of the presence of viral nucleic acid and whether an immune response to the virus has been mounted is needed. The purpose of this study is to determine whether personnel and patients/clients in healthcare in Region Stockholm have a currrent SARS-CoV-2 infection or have had an infection. This information will be used to understand how the infection spreads in healthcare, to explore the association with sick-leave among personnel, and to plan high-quality and safe care. Healthcare providers and organizations participating in the study from the greater Stockholm region include the following: Karolinska University Laboratory, Karolinska University Hospital; Intensive Care Unit, Karolinska University Hospital; SciLifeLab; KTH Royal Institute of Technology; Roo Home Healthcare Services (Roo Hemtjänst och Vård); Health Care Services Stockholm County (SLSO); Region Stockholm; Southern Hospital (Södersjukhuset); Danderyd Hospital; Capio St Göran Hospital; Södertälje Hospital; Tiohundra AB; Ersta Hospital, Sweden; and St Eriks Eye Hospital (St Eriks Ögonsjukhus).

Outcomes

Primary Outcomes

SARS-CoV-2 infection

Ongoing and past SARS-CoV-2 infection, measured in throat samples (current infection) and serum (past infection, antibodies to SARS-CoV-2) evaluated in relation to age, gender, sickleave, address, workplace, sampling date, work tasks (for healthcare personnel) and evaluated in relation to date of hospitalization, diagnoses, and interventions for patients and healthcare clients.

Time frame: Throat and blood samples are taken one time at enrollment. Other background characteristics are determined using linkages to healthcare employment databases up to two months after enrollment.
