Some scientists think long Covid is caused by lingering inflammation. Others think the virus might hide out in the body. Two years into the pandemic, scientists are scrambling to understand long Covid and find treatments. 

Bruce Levy is chief of the Division of Pulmonary and Critical Care Medicine at Brigham and Women’s Hospital. He now heads the Recovery Center, which was set up to treat and study long Covid.

We talk about risk factors for long Covid, the most common lingering symptoms, the different theories for its cause, the hunt for treatments and how the threat of long covid should shape people’s risk calculations.
