In 2009, Whittemore Peterson Institute scientists discovered a significant link between a newly-found retrovirus, xenotropic murine leukemia virus-related virus (XMRV), and the neuroimmune disease, ME/CFS. Their ground-breaking discovery was published in the world-renowned journal Science, on 8th October, 2010.



This discovery brought renewed interest to the much-maligned disease and a flurry of research was conducted in order to confirm the link.

On August 23rd 2010, US government scientists validated the link, announcing they had found an association between a family of infectious murine leukaemia viruses and ME/CFS. They reported that 87 % of those sampled carried at least one of the retroviruses, along with 7 % (1 in 14) of the healthy controls.





XMRV is similar to HIV, the retrovirus that causes AIDS.

Following the validation study several countries banned ME/CFS patients from giving blood. In many cases these bans are for life.

  1. thank you for taking your time and precious energy to bring accurate education on the matter of ME and the XMRV retrovirus. The governemnts need to take this very seriously for the sake of those 17 million who are already sick and to protect those who as yet are not.

  2. It is important to keep the press informed of the real science and not sensational stories. Thank you for posting these excellent links.

  3. Nice Blog Lothiane!
    Everything right on the point regarding XMRV. Nice to see
    research gathering pace and clearing things up.
    Keep well

  4. Good work! Great links. Thank you :))

    (And I agree with Tina re the Nobel prize. Who knows how many diseases may be associated with MLVs. The WPI may have set the ball rolling for something very, very BIG!)
