 In this study, the World Health Organization's definition of long COVID was examined, which is the persistence or development of new symptoms three months after the initial infection. Very few studies have looked into the presence of symptoms beyond this period, so this study aimed to explore the presence of a wide range of symptoms in patients hospitalized during the acute phase of COVID-19 infection and the association between these factors and the presence of residual symptoms after one year or longer from hospitalization. The results showed that up to 60% of patients had persistent symptoms at a mean follow-up of 17 months with the most common being fatigue and dyspnea. Neuropsychological disturbances also persisted in around 30% of the patients. When corrected for the duration of follow-up with a freedom from event analysis, only complete vaccination at the time of hospital admission remained significantly associated with the persistence of both physical and neuropsychological symptoms.
