Post-COVID-19 Complications and Recovery Patterns: A Cross-Sectional Clinical Study

Abstract

The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has left a significant global burden, not only in terms of acute infection but also through long-term post-recovery complications. This cross-sectional clinical study investigates the prevalence, types, and duration of post-COVID-19 complications among patients who recovered from moderate to severe infections. Conducted across multiple tertiary hospitals between 2022 and 2024, the study analyzed 1,200 participants aged 18–70 years. Common post-COVID complications identified included respiratory dysfunction, chronic fatigue, psychological disturbances, and cardiovascular irregularities. Data revealed that 63% of patients experienced at least one long-term symptom lasting beyond 12 weeks. The findings underscore the urgent need for structured post-recovery rehabilitation programs and multidisciplinary clinical follow-ups to improve the quality of life and reduce long-term morbidity associated with COVID-19.
