SARS-CoV-2 is a virus of the coronavirus family, which includes a large number of viruses that can cause a wide variety of diseases in humans. The SARS-CoV-2 virus causes acute symptoms associated with the infection and can cause chronic conditions known as Post-COVID. To understand the prevalence and variety of Post-COVID a large observational study of health insurance data from Germany was set up. The exposed patients were identified by a diagnosis indicating a confirmed laboratory test for COVID.~The basic question concerns the burden of the Post-COVID condition. The study investigate which symptoms are more common in humans after the exposure to the virus compared to a matched unexposed cohort. Further will this be investigated in the subgroup of children and adolescents and those who have been hospitalized due to the virus infection.
The SARS-CoV-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 which symptoms are related to it. The aim of the study is to monitor the onset of these conditions in a large observational study consisting of German health insurance data.
