from great point Alex brought up in chat... if we go by a 7% of the average population has XMRV that could infer 470 MILLION people across the world have it! that so utterly dwarfs most other illness concerns it's mind boggling... if XMRV causes various effects in differing people, for a y et unknown reasons: ME for some, autism for others, cancer for yet another group...we could have one pathogen causing a vast amount of sickness. THIS WOULD BE SOMETHING TO RAM DOWN THE THROATS OF THE POLITICIANS ETC, if more supporting evidence for XMRV comes in. Talking a literal gawd damn plague!!
