Over two years since COVID-19 first spread across the world, scientists are just scratching the surface of what is known about the lingering effects of the virus. Perhaps the most prominent aftereffect is long COVID, also known as post-acute sequelae of COVID-19 or PASC. Last month, data released by the federal government showed that nearly one in five people who once reported a positive COVID case are currently experiencing symptoms of long COVID.
Now, researchers in Massachusetts have discovered a potential marker that could help inform the diagnosis and treatment of long COVID.
This biomarker, found in blood samples, was identified by investigators from Brigham and Women’s Hospital and Massachusetts General Hospital. They analyzed 63 plasma samples from patients with long COVID, according to a release.
