I didn’t discuss aerosolized spread at all. I only discussed hand washing.
If what you are saying is correct, many people get ill because they don’t regularly wash their hands. I highly doubt this. Do you really think the prime minister’s wife, Sophie Gregoire, got COVID-19 from not washing her hands? All the civilized people I know wash their hands plenty as it is, and possibly too often. I probably wash my hands over sixty times a day. Perhaps one hundred times. But I still always get ill around Christmas time when my vacation starts.
I agree with the OP in thinking that telling people to wash their hands is inane advice.
I believe more that people who get sick likely breathed in the germs at a time when their immune systems were lower or completely down, such as mine is at Christmas time.
Many germs are all around us all the time. We cannot hide from them. Rather, we need to get strong to overcome their omnipresence. We can hide from Covid for a while, but it will always be around. The only good thing we’re doing now is that we are avoiding overwhelming the hospitals. Other than that, we will still see many many months of COVID. Our economies will go to shreds, weakening our immune systems as we fight to survive without money.
People also need to challenge their immune systems to keep them strong (but not with financial stress).
What we’re seeing now is mass hysteria about death. Death from flus is unavoidable, though it is perhaps good to reduce the curve for a short time. Notice how they never compare Covid number of deaths to those from the regular flu. Those numbers are poorly collected for some reason.
