Treat this stuff as nonsense - I could buy into it, if it was measles or something. A person with MS in 1900 would have relapses (assuming had RR) and would see some recovery (steroids not used then to treat MS). I suppose they could die because of a bladder infection with no abx to speak of. It does seem a bit of an extreme statistic to show how the researchers / drugs companies / MS Societies have helped. I suspect that survival rates are better now, as they are for everyone, because of immunisation, better diets, good drinking water, better housing, anti-biotics, better healthcare.
