Welke groepen mensen testen positief voor corona?

From the start of the corona pandemic, LL sent out questionnaires to all Lifelines participants. We start with a weekly questionnaire but changed the frequently in bi-weekly and monthly overtime resulted in a total number of 18 questionnaires until now. At the begin we have a response of more than 50.000 participants but is it decreased to a stable number around the 30.000 participants for the last questionnaires. The questionnaire contains questions of various topics, such as, if they get a corona infection, symptoms, daily life, mental health, chronic diseases, vaccinations, use of medication, Corona related well-being, social life, lifestyle, work situation, measures and how they think about that.
We believe that this huge amount of questionnaire data can help us to get insight in the way how and why people get infected. We expected a difference in infection rate between groups in the population like living situation, work, age, etc. which can help to create the models. Eventually we can combine the data with governmental information of the active measures because this also changes the behavior of the people.
