Long COVID can follow one of eight different symptom paths, as patients suffer for months past their initial infection, a new study reports.
The eight identified "trajectories" show how long COVID can differ between patients based on its severity and duration, as well as whether their symptoms improve or worsen over time, researchers reported Monday in the journal Nature Communications.
"The variability we identified will enable future studies to evaluate risk factors and biomarkers that could explain why patients vary in time of recovery, and help identify potential therapeutic targets," lead researcher Tanayott Thaweethai, an assistant professor at Harvard Medical School and associate director of Massachusetts General Hospital Biostatistics in Boston, said in a news release.
For the study, researchers tracked nearly 3,700 adults who first contracted COVID-19 during the Omicron variant era, after December 2021.
