I'll add to go ahead and start carrying a bottle of saline nasal spray. Look it up on the web, as some have a few additives to add to the protection. Salt kills a lot of nasties that get into your nasal cavities. Also, if you are one to use hand sanitizer, you should use it only outside the house. Once you get home, use it once upon entering, then use soap and water for the routine type hand cleaning, while home. You want your body to get accustomed to the regular "germs" in your home.
Thanks MMM! I'll look into this.
