48% affected 6-18 months later
48% of those in a population-level study reported persistent symptoms, impaired daily activities, and reduced health-related quality of life in the 6-18 months after Covid infection across sociodemographic factors and pre-existing health conditions.
1 in 20 had not recovered at all and 1 in 9 had worsening symptoms over the course of the study. Being vaccinated before infection reduced the risk of 7 of the 26 symptoms evaluated by 25-40%.
