  2. Findings for Question: Intention of the question:
    Question 1 is intended to capture whether the respondents have ever been infected with the coronavirus (SARS-CoV-2). To avoid bias due to own “false diagnoses”, the question refers to a PCR test as evidence for the infection.

    Four of the twelve subjects answered in the affirmative and when probed, all four subjects confirmed that their infection had been detected by PCR testing:
    • “I first had a positive rapid test and then a positive PCR test.“
    • “I had a positive rapid test and then I went to the testing center and they did a PCR test. “
    • “It was more of a coincidence because my best friend tested positive with a rapid test. Then I bought a rapid test and it was also positive. And then I went to the test center. […] and I did a PCR test, which was also positive.”
    • “I did five rapid tests at home to be on the safe side. Of the five tests, four were positive. I then looked up a PCR testing center, made an appointment and had my PCR testing done there.”
    The remaining eight respondents (correctly) answered question 1 in the negative. One of these subjects explained that they had already had several positive rapid tests, but not yet a positive PCR test. The other respondents stated that they had not yet been positive, neither by a rapid test nor by a PCR test.
