Got it - thanks!
The slide at 30:17 is the slide to see. No COVID-19 in the air, but testing at air vents showed COVID-19.
I’m hopeful some additional research is ongoing now.
I think staying away from people who are obviously sick, social distancing to the extent possible (to avoid asymptomatic spreaders), and not touching common-use surfaces are all good ways to reduce risk.
Many of us are most concerned about the health care workers, because obviously they will be needed to take care of patients—we do not want them getting sick.
“(to avoid asymptomatic spreaders)”
No such thing. The state of the virus in which it can affect others arises only when an infected person is showing symptoms - already sickened by the infection. Can someone “appear” to not have symptoms (and even deny they do).
Yes. Anyone with any flu, flu-like symptoms should self-quarantine; order in their food and have delivery folk leave it at the door. But people should do that for flu anyway.
