Multi-year Long COVID study
In February 2022, C-support, together with Erasmus MC, launched a large-scale, multi-year study into Long COVID. Individuals who were registered with C-support up to January 2022 with long-term symptoms following a COVID-19 infection and who completed the first questionnaire are invited annually to complete an extensive questionnaire. To date, there have been three rounds of questionnaires: more than 11.000 individuals have completed the first questionnaire , and approximately 8.000 individuals have completed the second and /or third questionnaires.
Below you will find an overview of the topics per questionnaire and more information.
