Holy crap, this just made me paranoid about babies and their health in general. If anyone can allay my (newfound) fear by explaining why this might be overly sensational, please chime in. I’m suddenly extremely relieved my nieces and nephew are old enough that their immune systems are getting practice in the real world.
I remember when my friends’ baby was a premmie and I had to wash my hands before holding him. Now I think that should apply to all newborns. That much, I think, is reasonable and not paranoid.
