 This study examined the characteristics and symptoms of patients seeking treatment for post-COVID syndrome, PCs. It also assessed the impact of symptoms on their health-related quality of life, HRQL, and ability to work and perform activities at daily living. The results showed that a large majority of these patients were of working age, 18-65 years old, with a mean age of 48 years old and 71% being female. Additionally, 51% had lost at least one day of work in the past four weeks, while 20% were unable to work at all. Furthermore, fatigue was found to be the most common symptom among those with PCs, accounting for the majority of variants in functional limitations. This suggests that fatigue should be addressed as the primary focus when treating patients with PCs. This article was authored by John R. Hurst, and Blandford, William Henley, and others.
