NIH study identifies eight long COVID trajectories
NIH’s RECOVER initiative published peer‑reviewed findings Nov. 17 in Nature Communications mapping eight distinct symptom patterns experienced by long COVID patients over 3–15 months. The 3,659‑person cohort (69% female; almost entirely Omicron‑era infections) shows courses ranging from persistently high symptom burden to fluctuating, improving, late‑worsening, and rarely symptomatic paths, which researchers say is critical for tailoring care and research.
