Staying away from people who have the flu is not enough
So, an inevitable following question is how to protect against the flu, given its potential harmful effects. Doctors recommend that those who have multiple sclerosis go above and beyond the normal precautions. The virus can be spread when someone who has the flu coughs, sneezes, or even talks - so effective protection is of the utmost importance. The CDC says that flu droplets are capable of moving as far as two yards in the air, so even when you think you are staying away from those who may be contagious, you might not be.
