XMRV  refers to a recently discovered retrovirus called xenotropic murine leukemia virus-related virus.  It  was first identified in 2006 in samples from men with prostate cancer and later to chronic fatigue syndrome. There are only 3 known human retroviruses: HTLV, HIV (which leads to AIDS), and now XMRV. In 2009, researchers reported finding XMRV DNA in two thirds of 101 people with chronic fatigue syndrome (CFS) but in only 4% of healthy controls. [1] It has also been proposed to be the cause for conditions including autismfibromyalgiamultiple sclerosisamyotrophic lateral sclerosis, and Parkinson’s disease. Later research could  not find a correlation. [3]

A primer for XMRV, XAND, M.E. – and CFS By Mary Schweitzer, Ph.D.


Interesting Note From Wiki:

Public health officials have voiced concerns about the donated blood supply, citing the potential dangers should XMRV prove to be an infectious human pathogen.

Interesting fact- from the CDC site:

While it is presumed that XMRV and MLVs can be transmitted through blood transfusion, no such transmission has been identified, and there are no known cases of XMRV or MLV infection or related illness in transfusion recipients. Therefore, there is currently no requirement for testing of the blood supply for the presence of XMRV or MLVs.[4]
