Is Mouse Virus Linked to Chronic Fatigue Attack?

In one of the recent studies, US scientists have retracted some part of 2009 study belonged to the journal Science which linked chronic fatigue syndrome with mouse virus. This is because as per the recent experiments, mouse virus is considered to be the cause of mysterious disease. According to the journal, Science which was published recently also casts doubt on the new theory. As per the study, there were no traces of XMRV virus or any related mouse virus in blood samples which were taken from healthy people and those with chronic fatigue syndrome.

The chronic disease causes muscle pain, memory loss and overwhelming fatigue. According to the scientists, the linking of chronic fatigue to mouse virus is perhaps the results of the contamination of lab samples. While initial research discovered XMRV in the blood of two-thirds of patients who suffers from chronic fatigue syndrome, a study which was conducted recently rubbished the claims which were done in 2009. Hence the research studies in Nevada and Maryland teams are now in question. Several studies conducted by National Cancer Institute, University College London and Oxford University have suggested that there is a possibility that the earlier samples were contaminated. Following the report, Dr. Robert Silverman and Jaydip Dasgupta of the Cleveland Clinic who were the authors of the 2009 paper which was published in Science have cross checked their experiments and found that some of the samples from chronic fatigue patients could have been contaminated with a laboratory form of XMRV genetic material.

Mouse virus

The reports of XMRV and related mouse virus which were circulating in the human blood have raised serious concerns of the supply of blood. In June 2010, the non profit US blood banking association (AABB) have advised the blood collection centers not to collect blood from donor who has chronic fatigue syndrome. This has prompted US Department of Health and Human Services to conduct tests on the blood sample of healthy people as well as among 14 patients who had chronic fatigue syndrome and were tested positive for XMRV and P-MLV. The samples were sent to different labs including CDC and US FDA. Some of the reports turned out to false positive.


An official statement released from Cleveland Clinic agreed to the report and also said that authors no longer believe XMRV is linked to chronic fatigue syndrome. The non-curable chronic fatigue syndrome attacked one to four million Americans.
