This isn't new information except that it's being highlighted directly by the NIH, instead of news orgs reporting on the preprint. There also doesn't seem to be any attempt at reproduction so far. So, good information to have, but we can't take the numbers as literal and absolute -- more like a lower bound.

It also isn't necessarily sufficient for the virus surviving on surfaces to be able to infect someone. If the virus needs to find its way into your lungs to infect you, and it is part of some surface matter that doesn't aerosolize easily, then the virus surviving on surfaces may not be able to actually infect people.

  I don't know that aerosolize is the problem so much as people putting their booger hooks up around their mucus membranes around their face - after touching other surfaces, that is. (edited to add that bit, since that's the important part)

  People touch the surface, then their faces. Inhaled aerosols are not a significant component of how this virus spreads. Touched surfaces with viral films, and inhaled droplets, are.

    This is a direct contradiction to what the CDC has been saying from the beginning, and continues to say: > The virus is thought to spread mainly from person-to-person. > - Between people who are in close contact with one another (within about 6 feet). > - Through respiratory droplets produced when an infected person coughs or sneezes. > These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.

      The fact that it's not "thought to be" the main way... Says nothing about whether it's still significant and something worth trying to avoid. Frankly, the fact that the CDC hasn't changed the guidance also means next to nothing, because we're not collecting information about anything other than the most obvious cases. I'm not saying that the guidelines shouldn't be taken into account, nor ignored: just that they seem more likely to be of the "take two aspirin and call me in the morning" variety, i.e., common rather than informed and specific advice.

      That is an interesting article, but just so we are clear, he repeats exactly what I said: inhaled droplets. He then goes on to say inhalation of droplets is not historically what is referred to as “droplet transmission,” and goes on to discuss aerosols. So... ok.
