Hi free at last
A conservative estimate of XMRV prevalence is more like 5% as I have said at length elsewhere, and the worst case is about 10%. Remember that the 3.7% figure is for healthy people. For true prevalence you have to combine healthy and ill prevalence - not easy when we still don't have good data, but much more than 4%!
The following is based on the wikipedia HIV prevalence rates:
HIV prevalence in Australia is 0.1%. This would make worst case XMRV 100x more prevalent (oops, I think my prior post said 1000x, that was an error!), and the likely ratio at 5% XMRV prevalence at 50x. HIV prevalence in the USA is 0.6%, which would make the worst case 16x worse, and the likely case 8x worse.
Lets suppose you only want to use the 3.7% figure. In Australia, XMRV prevalence would be 37x worse than HIV. In the USA, it is 6x worse.
Of course, in Lesotho (South Africa) the prevalence is 28%, so HIV is 7.5x worse than XMRV (using 3.7% XMRV prevalence) ... ahhh, but we don't know how HIV and XMRV interact, or what this does to prevalence rates. If we use an immunocompromised prevalence rate (the only one we have for this) of 10%, then HIV is potentially only 2.8x worse than XMRV prevalence in Lesotho (South Africa), the most HIV country (kingdom in this case) in the world! Doing a little more math to only use the 10% XMRV figure for the 28% with HIV, total XMRV prevalence is 5.5%, we get HIV prevalence as only 5x worse than XMRV.
If HIV is a pandemic, then so is XMRV, unless we can PROVE it is harmless, at least as far as risk assessment is concerned. In risk management, you have to look at average and worst case scenarios, not just best case wish fulfilment or authoritative apathy. There is also the issue that while both remove productivity from the work force, HIV kills but XMRV probably kills and disables, putting increased financial pressure on the world. (Yes, we are all aware this is not proven yet, but in risk assessment this is
not that important, it just another factor in how seriously to take the risk.)
Here is the wikipedia comment on pandemic, for reference:
A pandemic (from Greek πᾶν pan "all" + δῆμος demos "people") is an epidemic of infectious disease that is spreading through human populations across a large region; for instance a continent, or even worldwide. A widespread endemic disease that is stable in terms of how many people are getting sick from it is not a pandemic. Further, flu pandemics exclude seasonal flu, unless the flu of the season is a pandemic. Throughout history there have been a number of pandemics, such as smallpox and tuberculosis. More recent pandemics include the HIV pandemic and the 2009 flu pandemic.
So I completely support the relevance of Judy Mikovits statements, even if they were taken out of context. This is serious until we can prove it isn't (not the other way around) which makes XMRV research a huge imperative -
especially to anyone who wants to prove this assessment wrong! This is underscored by the issue that we can't protect the blood supply yet (most people with XMRV are still giving blood and donating organs) and we have no strong evidence of other modes of transmission. To go with the status quo as default is to say we should use ignorance as a basis for public planning. So if you are pro- or anti-XMRV wtih respect to illness, disability or death, it doesn't matter - research is an extremely urgent priority and needs to be pushed as hard as possible.
I have sent two emails to the Australian minister for health about these issues, the first last year. I take it seriously. I do not email tabloid newshounds about this - I know they will try to fan hysteria (yep, the real deal). Responsible journalism is the name of the game here.
Bye

I dont think Judy M was comparing Symptomatic ME CFS to AIDS at all, I think the point she was trying to make is, what XMRV might lack in a lethal symptomatic way. It could certianly make up for in the huge amounts of people worldwide becoming infected.
what is the infection rate of HIV in the united states Compared to XMRV ? I honestly dont know. But i dont think its anywhere near 4 out of 100 people. That i feel might have been her message,
