Long COVID Kids DK - Investigating Long-term Covid-19

Exposure: To be identified as an exposure for the current study, children from 0-18 years with at least one positive SARS-CoV-2 test will be identified from COVID-19 data from January 2020 until the last updated version. To be able to identify the parents who will receive the questionnaires we will also need CPR-data on the children's parents.
