I think JC Virus is mentioned by MS patients because it increases the risk of developing PML when you are on Tysabri. I understand about 50% of the population does carry the JC Virus, (I know I do), and my neurologist told me that in the first year of getting Tysabri, the risk of getting PML is about 1 in 4000. The risk increases the longer you take the medication, and apparently I am now at a risk of 1 in 150, so they are giving me 6 monthly MRI scans and I have been nagged to get in touch if any new symptoms arise. However, I am much better on Tysabri that on the Beta Interferons that I had for about 2 years before that, and I would definitely recommend it if you are being offered it. Good luck!
