That’s one spot, not a trail behind them like if they are constantly breathing out that you are walking through continually.
It’s one instantaneous exposure vs a continuous 20-30 minute exposure.
Walking behind someone and breathing in whatever they are exhaling is going to leave you a far greater exposure than passing through one isolated spot.
You are suggesting the person walking along is leaving a substantial cloud of virus particles as they continue on. Viruses are not nearly as communicable is that and you have to stay within a fairly close distance for about 6 minutes to be at serious risk of picking up much of anything.
If they were leaving that much out there it wouldn’t matter which direction you came from.
In terms of communicability this virus is no more communicable than the flu. And while it appears to have a very slightly higher mortality rate than the flu, people forget that the flu is pretty darn dangerous for a lot of people. In January of 2019 my wife my daughter and I also got the flu they both acted like they had a mild cold for about a week. 3 days into mine it morphed into a very serious case of pneumonia which hospitalized me for 4 days and came close to shutting my kidneys down. And I’m in good health.
Do you think that we should have these same procedures during the flu season for four months every winter?
We should be taking the same general precautions that we take during the flu season, at least those of us who are cognizant of the need. We don’t need to shut down the entire country and ruin the lives of millions of people and have millions of others living in abject terror.
I have a friend in Florida who is terrified to even step out into her backyard which is enclosed with an 8 ft high fence. It has basically turned her into a complete recluse for the last several months and destroyed her quality of life. The same thing has happened to millions of people. I seriously doubt if she will ever be back to completely normal. In my opinion what has been done to her and so many others is nothing less than criminal.
Sorry for the rant, I just had to have my say.
