Xlear nasal spray KILLS the COVID virus where it lives, in your nose.
Inexpensive, available at Walgreens, Amazon $25.58 for a 3 pack.
I use it daily.
Thanks, I went to Walgreens after reading your post and bought some Xlear. It looks like it's saline nasal spray, so maybe the Simply Saline nasal spray I've been using to fight allergies has also been protecting me from the 'rona.
