We have never claimed that CFS was caused by XMRV,only that CFS patients possess antibodies to XMRV related proteins and harbor infectious XMRV, which integrates into human chromosomes and thus is a human infection of as yet unknown pathogenic potential.Contrast with:
We are testing the hypothesis that XMRV is to CFS as HIV is to AIDS. There are many people with HIV who don’t have AIDS (because they are getting treatment). But by definition if you have ME you must have XMRV.And see for reference:
Testing patients which don’t satisfy rigorous clinical definition of XMRV such as is required in the Canadian Consensus Criteria.What a piece of bullshit.
That is a constant nuisance, that Mikovits/WPI equal their "XMRV findings" with ME/CFS.
