The CFS program will remain in the Chronic Viral Diseases branch, where it has been. It's NIH that has the CFS focus in the Office of Women's Health.
CDC is going through a massive re-org, as many of you already know. Most posts are temporary/provisional while it all gets sorted out, but it will happen on CDC time (read: sloow). Unger has experience in viruses and cancer, both relevant to CFS research. Like Suzanne Vernon, she is not a believer in the early childhood stress theory as the explanation for CFS. Unger has her name on that research paper because of her involvement at the lab. First authorship is most important, but it is also my understanding is that asking to have your name removed from a paper is kiss of death in science.
Personally, I continue to be cautiously optimistic. I think 2010 needs to be all about building momentum, finding consensus, and pursuing scientific progress. This change in leadership MAY represent an opportunity to do just that.
