This may sound ridiculous to some. But I put two squirts of a saline nasal spray in each nostril once a day. It’s called Xlear nasal spray and has xylitol and grapefruit seed extract.. For a while they were trying to get emergency usd authorization for covid but I don’t think it happened. You know how people use xylitol gum or mouthwash because it kills bacteria they claim it can rinse out your nostrils. Not sure if it really works but any time I think I might get exposure like when I had oral surgery I sprayed a few more times in a day. Plus my son brought home a monster cold from high school I caught it but sprayed every six hours it never blossomed and went away in a few days. So it can’t hurt but not sure if it helps. Still use it religiously.
