In a 2009 study, researchers doubted that there could be a link between a virus called XMRV (xenotropic murine leukemia virus) and chronic fatigue syndrome. Dr Judy Mikovits, the author of the study, said that the retrovirus XMRV was frequently present in the blood of chronic fatigue sufferers, yet without establishing a causal link.
This controversial finding caused a stir and led other scientists to try to confirm whether chronic fatigue syndrome was caused by a virus.
However, the paper was retracted by its publisher, the journal Science meaning that the mousse virus does not link to chronic fatigue syndrome. The reason for the paper withdrawing decision is explained that the Thursday Science had “lost confidence in the report and the validity of its conclusions” after multiple laboratories, including those of the original authors, failed to detect the virus in chronic fatigue patients.
Chronic fatigue syndrome is a mysterious disease that can last for years and can be the cause of weakness, muscle pain, impaired memory and/or mental concentration, and insomnia. It may be trusted that the fatigue can be caused by different causes but not the XMRV (xenotropic murine leukemia virus) that might cause cancer and other diseases in mice but not in humans.
