Through SARS-CoV-2 IgG testing of PCR positive and negative cases the study will follow the COVID-19 immune response by monitoring the SARS-CoV-2 IgG antibody levels over a period of two years. Further, risk factors will be identified by the use of the test-negative design including population controls, allowing comparison of participants with positive and negative tests, and with population controls (triangulation). Special emphasis will be on high risk groups in general and on different occupational, environmental and socio-economic groups in particular. Finally, severity of illness, deaths and the use of health care during will be assessed using national register data from Telemark and Agder.
