:: You are wearing masks to protect others from getting what you have. ::
So, only those who are symptomatic and shedding viral particles should wear a mask.
But, if you are symptomatic, shouldn’t you be at home in bed rather than going out to the grocery store?
I know the inevitable response but I’ll let you say it anyway.
Last March, I had a cough so bad, I was having cramps in my abdominal muscles. My nose was running and my muscles ached. My son had the same cough and was running a fever. He tested negative. However, would I have tested if I didn’t have my son? I did go to the store at a time when masks were not being worn. I was coughing and wiping my nose. If it was the C-virus, I would have been a spreader. Thinking back at my behavior, I am embarrassed.
Now, I have a little raw feeling in my throat. Sometimes I cough. Should I quarantine myself? What if I was contagious before I had that feeling in my throat? I think wearing a mask as if you had the virus is the best policy; like wearing a seat belt. You may be an asymptomatic spreader.
