Study title

Full edition for scientific use. The main purpose of the study was to identify the number of people actually infected with coronavirus in Austria, as well as the number of people who have formed antibodies against SARS-CoV-2 and thus have been infected and further to report how people are feeling during this crisis. A representative random sample of 7823 people was drawn based on the population register of Austria (people living in Austria, exluding those currently in hospital and those aged younger than 16 years). The estimated percentage of SARS-CoV-2 infected persons in the Austrian resident population aged 16 and older was 3.1% on average in mid-November [95% confidence interval: 2.6-3.5%]. From the beginning of the coronavirus pandemic until mid/end of October 2020, 4.7% of Austrian residents (people aged 16 and over living in private households) had formed antibodies against SARS-CoV-2 and thus have been infected with SARS-CoV-2 [95% confidence interval: 3.8-5.6%].
