Longitudinal Changes in Characteristics of COVID-19 Survivors and Their Long-term Follow-up Study

From December 2019, coronavirus disease 2019 (COVID-19), caused by a β-coronavirus known as
severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread across the globe.
Numerous studies have been performed so far to investigate clinical characteristics, risk
factors, potential treatment and pathogenesis of COVID-19. However, little information is
available on the long-term prognosis and possible sequelae of COVID-19 survivors who have
recovered and been discharged from hospital. Hence, the investigators conducted a prospective
study to investigate the long-time prognosis and the possible sequelae of COVID-19 survivors.
The investigators evaluated Demographic and clinical characteristics, laboratory and
radiological findings,pulmonary function tests, electrocardiogram, complications as well as
treatment and symptoms and signs of COVID-19 patients.
