In March 2020, the LBI for Pulmonary Health decided to conduct an antibody study due to current developments in the COVID-19 pandemic caused by the SARS-CoV-2 virus. The aim of this study is to find out the actual frequency of COVID-19 infections in the Viennese population.
For this research project, a representative sample is required. Due to the core project of the LBI for lung health, the Austrian LEAD Study, in which already more than 11,000 test persons (from 6-80 years of age) were subjected to a "Health examination survey", such an exemplary representative sample from the general population was available. This population sample was invited to an antibody test from April to May 2020. In total, more than 12,000 Viennese were examined. In addition to the frequency of COVID-19 infections, the number of asymptomatic infected persons could be deduced. In addition, the LEAD study database also allows conclusions to be drawn about socioeconomics, lifestyle factors and risk factors of Viennese who tested positive for Covid-19.
