: We followed the ethical guidance of informed consent (WMA, CitationRef removed), and the participants were informed of the following at the very beginning of the survey: “We will ask you some personal questions, such as whether or not you have ever contracted COVID-19. All the questions are structured such that you do not have to answer them. You can skip right on to the next question or simply close the browser. The survey is completely anonymous, and we cannot draw any conclusions about the identity of the participants. You can even declare that you want to end your participation now. To do so, simply click the relevant box. Otherwise, click CONTINUE.” Next, the participants indicated either “I would like to take part in the survey, but I can opt out at any time” or “I do not want to take part in the survey.” Out of all individuals worldwide to whom the survey was sent, approximately 1% decided not to take part in the survey.
