 This study found that a large proportion of patients experienced symptoms up to 12 months after being hospitalized for COVID-19, with muscle weakness, exertional dyspnea, fatigue, and memory and concentration problems being the most common. These symptoms gradually improved over time, but fatigue and cognitive symptoms did not show any significant improvement. This article was authored by L. Martin Beck, Julia C. Berinchott, Majanka H.
