I'm guessing your brothers are young-ish. If that's the case, statistically, they'll do just fine even if they do catch it. I'm much more concerned with you and what it may do to you. I'm sure your mom and rest of the family are on it, so I'm not too worried other than my usually worrie-ness! (I'm just a worry-wort at heart...)
But I do get it's nice/comforting when the family is all home and safe. Nothing better than that in the whole wide world!
