I just did some rough mathematics on future XMRV costs in Australia. If I use a 10% prevalence rate, I get 2.2 million (I have argued for this percentage elsewhere). If we presume the cost of treatment will be $10,000 per patient, per year, that is a cost of 22 billion per annum for Australia. Of course we can decide not to treat it, and allow the virus to spread. I do want to, again, make the caveat that XMRV has not been proven to cause any illness. This post is about risks, not proven fact. If we presume that XMRV is spreading at a rate of 1% per annum, then this cost is increasing by $220,000,000 per annum, as an ongoing cost. That is around $602739 for every day of inaction, added to direct medical costs for generations to come. Every day of inaction is like a minor disaster, every year is a catastrophe. It has been 485 days since the Lombardi paper. Inaction has therefore increased the eventual annual cost by $292 million dollars. What country can afford to lose that kind of money for generations to come? Please run the numbers for your country. Feel free to alter the percentages - say 4% infection, or 7%, or a transmission rate of 5%. Whatever numbers you run it is scary - and Australia only has a population of 22,000,000. What is it for Europe or the USA?
