Previous studies on long-COVID's natural history have been limited and lacked comparison groups. The Long-COVID in Scotland Study (Long-CISS) used a Scotland-wide cohort of adults with confirmed SARS-CoV-2 infection, matched to PCR-negative controls. Serial questionnaires assessed health at 6, 12, and 18 months post-infection. 53% of those with prior symptomatic infection reported persistent incomplete recovery. While taste and smell improved over time in the infected group, late-onset dry productive cough and hearing problems were more common post-infection.
