Up to 20% of patients with Covid-19 develop symptoms that last more than 3 months, which is known as long Covid or Post-Covid-19 condition. The mechanism of the long term symptoms is not totally understood although inflammation, autoimmune reactions and thromboembolism are among suspected contributors. At Helsinki University hospital, a long Covid clinic was opened in June 2021. The aim of this cohort study is to monitor the patients that attend the clinic, follow up their functional abilities, quality of life and prognosis.
