Syndrome symptoms - long and strong fatigue, and also pains in various parts of a body. Sometimes as the weariness reason consider the general delicacy of health or problems with mentality, writes The New York Times.
The group of scientists headed by E.Mikovits, has published results of the researches in article on magazine Science site. As researchers have established, at 68 from 101 surveyed with this syndrome (67 %) virus XMRV has been found out. In control group of healthy people the virus is taped only at 3,7 %. During the further researches this virus found almost at 98 % of patients.

XMRV (the virus of a mouse leukaemia (xenotropic murine leukaemia virus-related virus) concerns type the scale-retroviruses, this virus, like AIDS virus, infects an organism for life. As it has been proved earlier, this version of viruses cause a sarcoma and a leukaemia in animals.

Recently American scientists have proved, what exactly this virus can cause a cancer of a prostate which becomes a cause of death of 10 % of men. At research of samples of cancer tissues scientists in every fourth have found out virus XMRV.

While scientists did not manage to prove, that virus XMRV causes a syndrome of chronic weariness. As the researchers note, any communication nevertheless is, though, probably, patients with a syndrome of chronic weariness are simply more vulnerable before an infection, and the syndrome has other reasons.
As doctors speak, the weariness - a natural phenomenon and serves as an alarm signal necessary for survival rate. The weariness becomes a pathology if does not disappear after rest.
