Long COVID Clinical Features in Northern Taiwan: Insights from a Single Medical Center Study

Older age and hospitalization significantly predict long-term quality of life impairment in long COVID. Targeted interventions for these groups and robust post-recovery support are essential. Limitations include reliance on self-reported data, a low vaccination rate (7 %), a 3-6 months follow-up, and a single-center design, which may limit generalizability. Multi-center studies with longer follow-ups and objective biomarkers are needed to enhance further understanding.
