Nearly two years into this pandemic, doctors still don’t know much about why some people develop long lasting COVID symptoms and why others don’t. But, a study published last week by the scientific journal Cell, found several factors that were identified early in a person’s coronavirus infection that could show increased risk of developing long-term symptoms.

Some studies show that as many as half of COVID-19 survivors experience some sort of lingering symptoms, these patients are known as “Covid long-haulers.” We heard from listeners about their long-term Covid symptoms and from one of the leaders of a Covid long hauler group.

We also spoke with Dr. Jason Goldman, infectious disease clinician and researcher at the Swedish Medical Center in Seattle, Washington and lead clinical author of this study on long-Covid.
