Just a reminder that R0 for SARS-CoV-2 may in fact be higher than 2.5-3.5.

In fact, perhaps even double that (R0 = 5-7) https://twitter.com/jmcrookston/status/1297571423041585153

(or higher)

New variant increases R by 0.4 to 0.96 or whatever. https://twitter.com/jmcrookston/status/1340690340832014338

So

- even starting with R0 ~ 2.5 to 3.5 that's now R0 ~ 3 to 4.5.

- starting with R ~ 5 to 7 that's R ~ 5.5 to 8.

Some have calculated above 5 to 7, esp. once superspreading starts rolling (higher cases).

So, aside from
- no proof of droplet
- no proof of fomite
- air scientists saying, this is in the air
- virus and RNA on vents
- culturing virus from the air
- outbreaks of rooms of people
- outbreaks after index leaves room
- outbreaks indoors

... it's still droplet because R0?

Clearly one answer here.

Avoid indoor, and definitely no small indoor rooms. Windows open. Ventilate. Masks on.
