**A prospective study of nearly 1,020 adults found that long COVID symptoms improved in half of participants after three years, though recovery rates depended on symptom subtypes.**

Symptoms of long COVID eased in 50% of patients within three years of their initial SARS-CoV-2 infection, according to findings from the U.S. RECOVER Adult Study published in the Annals of Internal Medicine and reported by livescience.com [1]. Funded by the National Institutes of Health, the prospective study tracked nearly 1,020 adult patients across the United States who scored more than 10 points on the 30-point 2024 LC Research Index (LCRI). Participants completed in-person evaluations and questionnaires every three months to monitor issues including fatigue, cognitive impairment, shortness of breath, and palpitations [1].

Investigators defined clinical improvement as reaching an LCRI score of 10 or lower across two consecutive visits. The data showed that 36% of participants reached this threshold two years after infection, increasing to 50% at the three-year mark [1]. Additionally, 26% of patients recorded an LCRI score of zero at three years, signaling that all tracked symptoms had resolved at the time of assessment [1]. Co-author Harrison Reeder of Massachusetts General Hospital noted that researchers avoided the term "recovered" because symptoms can fluctuate, and the protocol did not assess whether improved patients later experienced relapses.

## Subtype Disparities

Patient trajectories varied sharply based on underlying symptom profiles. Roughly 60% of individuals whose primary symptoms involved loss of taste or smell improved within three years. Conversely, fewer than 20% of participants with multisystem symptoms—specifically 19% in the most complex presentation involving cardiac, nervous, and gastrointestinal manifestations—showed improvement over the same period [1].

## Clinical Trial Implications

Age and viral lineage also influenced long-term outcomes. Participants under 46 years old and those infected with Omicron variants were more likely to show improvement than older adults or those infected with earlier viral strains [1]. Commenting on the findings, Dr. Carmen Scheibenbogen of Charité University Medicine Berlin observed that the multisystem cohort closely resembles patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Both Scheibenbogen and Reeder emphasized that future clinical trials evaluating targeted therapies must account for these distinct clinical subtypes [1].
