The common cold and the common flu, to name just 2 existing communicable diseases, are also highly transmissible and can be transmitted through the air. We knew this, and lived with the minuscule level (but not non-existent level) of risk of serious illness or fatality. No one ever talked about venues such as shopping malls or schools as “super spreader” venues for the transmission of colds (although clearly they were and are). Our new hyper sensitivity to a new communicable disease which is not much more deadly (not initially, and certainly not at this point) than existing common diseases is nothing other than paranoia.
I see you're the type who doesn't believe COVID is a serious health issues. You are entitled to your opinion. Facts, on the other hand paint a different picture. The flu or common cold do kill people (as do its vaccines).But, covid kills people at a higher rate. Now, of course you can argue that it hit those with underlying health issues...but so does the flu. Now, I'm a triple vaxxed person in fairly good health. I think if I caught it now, I would likely fight it off and live. What worries me is the damage this disease can do. Again, there doesn't seem to be a guarantee that it'll happen in every case, but people have had major organs damaged, suffered blood clots and strokes, and then there is the threat of "long haul covid," which hits a certain number of people. They might have caught the disease a year ago and are still feeling crappy.
I don't want to face that risk. While we've learned a lot in the past year, there is still a lot that we do not know. We are still learning about the longterm issues that this disease can cause. I don't want to die, I don't want to suffer long term effects. I also don't want others to suffer that fate.
But, saying someone is concerned about dying from this is not being paranoid.
