Is There a Biochemical Pathway to Long COVID?

Dr. Adam Seifu: I'm a little bit pessimistic that we're going to come up with anything because it's going to take some serious breakthrough to figure out what's actually causing this problem, people. It affects every organ system but not a single of the 200 biochemical pathways. He says there probably is a biochemical pathway that we haven't recognized and that's why we can't treat it. "It's not nice to be a doctor with nothing to help anybody with," Dr. Seifu says.
