Interesting post from a few minutes ago, as a comment to an article in today's New York Times on the viability of the virus on various surfaces and infectiousness as aerosol or fomite:

Infective Viral Load is the amount of virus that can cause infection with a moderate to high degree of probability. Below that threshold, viral loads in the environment are so low that the controlled incidence of new infections ensures an epidemic is ending. That is a different question than the danger to each individual, which may be reduced, but is not eliminated in the presence of only small viral loads of aerosol and fomite virus. As long as any virus is present, there some minimal risk of mortality because a single virus entering an ACE II receptor can eventually kill a person, even if that is unlikely. Risk is only reduced therefore, not eliminated, with reduced exposure to fomite and aerosol viral load. Absolute safety would require, e.g., a 2-3 week quarantine during the incubation period for any person exposed to persons shedding the virus or other vectors that include both shopping and social distancing. The reader should be told not “what is safe,” but what is “kinda safe,” and let them assess their appropriate degree of worry, concern, risk-taking and prophylactic safety measures accordingly.
