Approximately 400,000 Americans have MS, and every week about 200 people are diagnosed. World-wide, MS affects about 2.5 million people. Because the Centers for Disease Control and Prevention (CDC) does not require U.S. physicians to report new cases, and because symptoms can be completely invisible, the numbers can only be estimated.
I think the estimate of 400,000 is way off. That number was the estimated figure when I was diagnosed and for many years before that.
How many people really do have MS? If it’s true that 200 new cases are reported each week, then we can assume that there are over 10,000 new MS patients per year!
