Post-COVID-19 Monitoring in Routine Health Insurance Data With Focus on Autoimmune Diseases (POINTED-AD)

The SARS-CoV-2 (Severe acute respiratory syndrome coronavirus type 2) infection was in 2020 responsible for new disease related chronic conditions which have been referred to as Post-COVID. To date it is still unknown how common this condition is and how it might effect the working of the Immune system. The aim of the study is therefore to monitor the onset of autoimmune diseases in a large observational study consisting of German health insurance data.
