Brief Summary:
The objective of the study is to estimate the prevalence of anti-JCV antibodies in multiple sclerosis (MS) participants.

Condition or disease
Multiple Sclerosis

Detailed Description:
This is a cross-sectional, multi-center, multi-national, epidemiological study to estimate the prevalence of anti-JCV antibody in MS participants. This study will provide an estimate of the prevalence of anti-JCV antibody in the MS population and will investigate inter-country differences.

Study Type : Observational
Actual Enrollment : 7726 participants
Time Perspective: Cross-Sectional
Official Title: Epidemiology of Anti-JCV Antibody Prevalence in Multiple Sclerosis Patients
Study Start Date : September 2010
Actual Primary Completion Date : May 2012

Primary Outcome Measures :
  1. Prevalence of anti-JCV antibodies [ Time Frame: Single timepoint (Day 1) ]
    Prevalence of anti-JCV antibodies will be estimated as the number of participants with anti-JCV antibodies detected in serum divided by the total number of participants with a serum sample that was evaluated.
