What this trial studies

This observational study aims to investigate the distribution characteristics and clinical profiles of asymptomatic infections and diagnosed COVID-19 patients, particularly focusing on the omicron variant. It will assess disease outcomes, risk factors, and changes in multiple organ functions, including cardiopulmonary health, over a long-term follow-up period. Additionally, the study will evaluate social and psychological indicators related to these patients' experiences.
