Background and purpose

An important part of the knowledge about the spread of infection of the SARS-Cov-2 virus that causes the COVID-19 disease involves obtaining information about the extent of the spread of both acute and historic infection and thus enabling scientifically-based modelling of future infection in different parts of Swedish society.

Getting a comprehensive picture requires both detection of the virus showing ongoing (acute) infection and the presence of antibody responses showing a previous infection. This study intendes to examine this with analytical platforms set up within the framework of the National Pandemic Centre at Karolinska Institutet (KI).

Thepurpose of the sub-study is to examine the extent of the spread of the infection spread in terms of viral load and to gain knowledge about the extent of the spread of infection in different parts of society. KI is now offering external groups the opportunity to take part in the study in order to form a more comprehensive picture of society. Participation requires having a BankID and access to a smartphone or computer. Participation in the investigation is voluntary.


With participation in the study, individuals register via the HOPE App developed and offered by ADDI Medical AB, where they will regularly receive information, appointments and test results. Study participants will also answer questions in the HOPE App.

Participants will receive a self-testing kit. The virus test will be taken at home or at the aged care residential facility on the same morning as the virus test is submitted –  each site has a designated place that is communicated via HOPE App. Results of the virus test are received via HOPE App within two days.

Broad participation in this sub-study

Employees and tenants at approximately ten aged care residential facilities, dentistry students, dentists, dental nurses at Karolinska Institutet and employees at a number of companies.
