It seems to me that some people with MS are like me and never... or very rarely... get a virus. The last virus I had was 5 years ago when I had flu. Since then I haven't had so much as a sniffle. And that flu was the first virus for a few years.
The explanation appears to be that the immune system is constantly in 'battle mode' fighting the MS damage which it thinks is a foreign body... so that any old run of the mill virus is immediatly zapped.
On the other hand, it seems like lots of MSers are always getting colds and flu so the theory obviously doesn't cover all MSers.
So as a piece of totally unscientific research, which camp do you fall in?
Also what type of MS do you have? I'm PPMS.
