There have now been 24 cases reported since Jan. 12, giving an average rate of 4.8 per month. Hunter said this would imply a further 29 cases by the end of December, giving an estimated 84 PML cases by the end of 2010.

Most of the recent cases seem to be in people on Tysabri 3 years and longer.

I still think the odds are in our favor if in the U.S. They are still in the 1/1000 even in the 24-36 month range which is the highest of pml cases. Of the 6 new cases one was in the U.S. I'm pretty sure that in the 3-4 year range there have been 4 pml cases (U.S.) but the unknown is how many have been on Ty that long... I do not know why they don't have this figure. My guess is more than 4,000...
I have done my counts from chefarztfrau info and gotten other info from Biogen.
