This randomised study aimed to understand if multidisciplinary internet-based interventions performed in group and individually are applicable for participants suffering from longterm COVID-19 syndrome. Data will be collected by internet platform at Karolinska Institutet (BASS) before, after rehabilitation and at follow-up after 6 months. Both self-scored questionnaires and physical tests performed at home will be collected to understand the symptomatology, functioning and activity level. Rehabilitation during 8 weeks period will be given in groups as face-to-group, pre-recorded film sessions and by individual approach, the participants will use ExorLive app for physical activity.~The participants will be randomised for treatment and waiting lists using a website random.org. Waiting list will be offered rehabilitation interventions after at least 8 weeks period of waiting to exclude a spontaneous improvement or worsening of symptoms. To understand the impact of rehabilitation on work capacity and employment/economic supply, the data from Social Insurance databas will be obtained 2021 year before and upp to 2 years after the intervention. To understand the impact of rehabilitation on sickness-leave, the data from National Insurance Agency will be obtained for 2021 and 2022.
