It doesn't have link to the developpement of MS.
It's a very frequent virus. When treating MS patients with biological therapies like natalizumab there is a risk of reactivation of JC virus and developpement of PML. That's why we do the serology in MS patients. If a patient is JC positive some treatements are countrindicated.

Like immunosuppressant therapies. My immune system is very weak (very low B cells). Do I have to worry ?
