Press release: 12.396-236/20
– From the beginning of the coronavirus pandemic until mid/end of
October 2020, 349 000 people in Austria 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: 282 000–420 000].
Of these infections about 61% were officially undetected (based on data
of the Austrian epidemiological reporting system). These are results
of the nationwide COVID-19 prevalence study by Statistics Austria and
the Medical University of Vienna on behalf of the Federal Ministry of
Education, Science and Research and in cooperation with the Austrian
From 12 to 14 November 2020, blood samples were collected
from 2 229 persons. Neutralising antibodies against SARS-CoV-2 were detected
in 92 samples. Based on scientific studies it can be assumed that virus-specific
antibodies can be reliably detected after a period of about three weeks.
Accordingly, the testing period from 12 to 14 November 2020 reflects
the infection situation in Austria until mid/end of October.
The estimated percentage of SARS-CoV-2 infected persons
that have formed antibodies by mid/end October in the Austrian population
aged 16 years and older living in private households was 4.7%.
