I think there are no spreaders out there, any more than there were Terrorists behind every bush, post 911. BUT, we did loose many of our rights.
I've told this story before several times... I'll tell it again. My first-hand experience with how fast one person can infect others unknowingly with a virus...
The night after my father's funeral home viewing, I got dizzy, started throwing up, curled up in the fetal position, my hands cramped closed and my legs locked up. I had tunnel vision and asked my wife to call an ambulance. Spent the night and morning in the hospital getting fluids and couldn't attend my own father's burial. At the church service, they had to get a different priest, because the main priest got violently ill. At the church, my brother-in law keeled over. His wife (my sister) keeled over at the cemetery. Several of my relatives left the funeral home the night before and got violently ill back home in Wisconsin. Another of my sisters keeled over after the burial. One of my cousins was a tough guy from the Navy. He didn't go to the Dr. for 3 days after the funeral. He went into renal failure and lost his kidney function. Had to get a transplant from his sister.
The culprit? Norovirus. Everyone crying, hugging, kissing, shaking hands spread it around. 8-9 of us needed hospitalization. Crap like that spreads fast. So, I have a pretty good first-hand experience with how fast poop can hit the fan.
I'm pretty convinced that people have illnesses, don't know it (or those that feel sick, but go to work anyway), and spread it around. No bad intentions, but it happens. Since we know that it can be spread from water vapor leaving your mouth and nose, and we know people spread it that are asymptomatic, why can't we all just agree to wear a mask when around other people, and stop being so self-centered/self-conscious?
