In presenting this study, Statistics Austria provides a valid assessment of the population acute infected by Coronavirus SARS-CoV-2 in Austria within three dates in 2020: April, May and November 2020. The population of these sample surveys includes people aged 16 or older living in private households. Participants were tested with PCR (polymerase chain reaction) tests using nose-throat swabs. Based on these tests, it is assumed that the number of acute Coronavirus SARS-CoV-2 infections was below 11 000 individuals, or 0.15% of the target population, in April, below 6 000, in May and below 265 000 in November (i.e. the upper 95% confidence interval). In November a comparison with the Austrian Epidemiological Reporting System reveals that more than 50% of acute infections remain undetected by the official reporting obligations.
