COVID-19 Prevalence November 2020 (SUF edition)

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%].

供科研使用的完整版数据集。本研究的核心目的为：明确奥地利境内实际感染冠状病毒的人群数量，以及体内已产生针对严重急性呼吸综合征冠状病毒2（SARS-CoV-2）抗体、因此既往曾感染该病毒的人群数量，并进一步报告民众在此次疫情危机中的身心状态。研究基于奥地利人口登记系统抽取了7823名具有代表性的随机样本，样本覆盖居住在奥地利的人群，但排除当前住院者及16岁以下人群。2020年11月中旬，奥地利16岁及以上常住居民中，估算的SARS-CoV-2感染率平均为3.1%[95%置信区间：2.6%~3.5%]。自新冠大流行起始至2020年10月中旬/月末，奥地利居住在私人家庭中的16岁及以上常住居民中，已有4.7%的个体产生了针对SARS-CoV-2的抗体，提示其曾感染SARS-CoV-2[95%置信区间：3.8%~5.6%]。
