Question and answer

Summary
Coronavirus Disease 2019 (COVID-19) as caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was a global unprecedented pandemic with more than 770 million confirmed cases and 7 million deaths up to Oct 2024. Increasing evidence suggests that a series of long-term complications known as long COVID at which fatigue, shortness of breath, cognitive complaint, and other respiratory, cardiac, and neurological symptoms are commonly reported. However, the importance and underpinning of sleep and circadian disturbances in Long COVID has not been well recognised. The Second International COVID-19 Sleep Study (ICOSS-II) group has conducted a harmonised multi-national survey across 16 countries/regions including Austria, Brazil, Bulgaria, Canada, Hong Kong (China), Croatia, Finland, France, Germany, Israel, Italy, Japan, Norway, Portugal, Sweden, and the United States of America (USA). The symposium will shed light on the importance of sleep and circadian disturbances as core symptom complex of long COVID, which will not only predispose to Long COVID complex and comorbidities, but also potentially increase future neurodegeneration risk. The importance of identifying sleep and circadian perspectives as a key component in long COVID will play a significant role in the future prevention and early intervention of epidemic/pandemic infection related morbidities.
