In view of the rising threat of transmission of XMRV, a deadly virus, Canada has prohibited patients of chronic fatigue syndrome from donating blood. However, no cases of transmission of the virus through the chronic fatigue have been detected, so far. But the Canadian Blood Services has initiated the move as a precautionary measure.

With this, Canada has become the first country to impose a ban on donations from people with chronic fatigue.

Dr. Dana Devine, Head of Medical and Scientific Research for Canadian Blood Services explained that there are basically two reasons behind the move. The first one is the lack of sufficient information about the virus and the second is the absence of the knowledge of the exact factor that leads to the development of chronic syndrome.

"Well, I think we're stepping out of the gate for two reasons", he said.

XMRV has been proved to be belonging to the family of HIV and its presence has been detected in some prostate cancer cells. The experts assume that its transmission may also be similar to that of HIV i. e., via blood transfusions.
