Getting the government to take action, including tests and clinical trials (research) on XMRV was a major theme of this press release from PANDORA:
http://www.pr.com/press-release/258171
PANDORA told CFSAC members in October that the XMRV finding should make all government agencies change the merry-go-round, pass the buck, that has been going on with this illness for decades. Marly compared it to how HIV changed things for AIDS. She listed many of the same points in the above press release.
Dr. Unger's department does not do XMRV research. But, the department of CDC that does XMRV research may get samples from her. That is why getting the research criteria right is so important. We have seen this with British studies.
Because she was new to the position, the goal of the letter was to discuss the action points that are under her authority.
Also, to our understanding, the area of CDC that is doing XMRV research is working in the blood working group with Mikovits, NIH and others.
Bill Switzer, who is seen here:
