Q. What should I do if I think I have Covid or any other illness while at a Folk Camp?
A. If you think you have Covid or any other infectious disease while at camp, please isolate until your symptoms ease and let a member of staff camp know. We form a close knit community at each Folk Camp and do not want to spread any illness. Folk Camps follows UK government guidance regarding Covid. For the 2025 season onwards, Folk Camps no longer provides Covid tests. Individuals are responsible for their own health whether they suspect Covid or any other illness. See booking condition 6 if you have any infectious disease.
