The latest figures show that the number of PML cases last month skyrocketed from 212 to 232!!! Don't know if any more deaths have taken place.

This is the largest jump in monthly cases that I can remember.

I notice that Biogen hasn't officially released the April 01 numbers showing an increase of the 20 additional cases of PML from March 01. I guess I wouldn't be in a hurry either to let customers know that info!

Another 10 more cases of PML in the last month bringing the total to 242. Don't know if any more deaths involved.
