But dude. This is anecdotal and might be true and worth noting. But in households totally exposed, not everyone gets it.
I had covid and had to physically while ill care for my mom with Alzheimer’s. There was no one else and I would not allow my young sons to potty and wash their grandmother. She was completely exposed to me right before I got sick and was surely contagious. Once I was ill, I was double mask and gloves but still doing everything to care for her. SHE NEVER GOT COVID. No one can believe it. And we didn’t take lactoferrin. And she has a million high risk factors.
So this virus is weird.
Sir, I salute you. And bless your Mother's heart!
