Misconception of how Covid-19 spreads might have led to initial decisions by various agencies to say that masks are not necessary.

So, they basically admit that the rationale behind masks, 6-feet distance, etc. are invalid, and then at the end, double down on the same advice. Why? Because admitting that (like measles and other viruses) this virus can spread from apartment to apartment, and in urban areas house-to-house, especially at night when wind speed is low, will panic people too much.

It appears that we are going to get the harsh, unvarnished truth (nothing but a vaccine really helps much) in small pieces, to see how much people can tolerate. But we are getting more than a year ago.
