Clinical Features, Therapeutic Outcomes, and Recovery Period of Long COVID

This study surveyed 286 patients with long COVID to analyze clinical features, recovery periods, and factors affecting recovery. Common symptoms included respiratory issues and fatigue, with hair loss emerging as a significant late-phase complaint and showing the worst treatment outcomes. Smoking was identified as an independent risk factor for prolonged recovery, while factors like sex, age, and comorbidities were not. The study proposed therapeutic options, including inhaled budesonide and herbal medications, but noted limitations such as a small sample size and lack of data on the Omicron variant and vaccination effects. The study emphasized the need for early intervention, smoking cessation, and further research to understand long COVID, treating it as a distinct disease from the common cold or flu.
