NEWSBRIEF: Researchers in Sweden are launching a study to further examine the link between XMRV and chronic fatigue syndrome (CFS or ME/CFS). Results are expected to be out in the spring or summer of 2010.
XMRV is a retrovirus that researchers recently linked to a substantial number of ME/CFS test subjects in the U.S. Further research is needed to validate or refute this finding.
However, it may be able to draw conclusions from 2 studies done in different areas of the world, because the prevalence of infectious agents can vary drastically from one region to the next. In either case, this new study could reveal differences in the prevalence of XMRV infection in different regions of the world. If the connection with ME/CFS holds up, the XMRV prevalence should correlated with the ME/CFS prevalence in any given population.
