A short period of time in close contact with an infected person (likely presymptomatic, so someone who seems perfectly healthy!) OR a longer period of time *distanced* but sharing the same air with an infected person -- BOTH of these scenarios can transmit the disease. https://twitter.com/CorsIAQ/status/1386023361998823425">https://twitter.com/CorsIAQ/s...

You can be sitting **across the room** from someone for an hour or two and still inhale their aerosols!

Mask up when inside. Move things outdoors, where the ventilation/air dilution is so effective that masks really aren& #39;t even necessary unless you& #39;re up in someone& #39;s face.

But for heaven& #39;s sake don& #39;t say "if people are worried about COVID they can just stay away from me while I do my thing." If you say this, you don& #39;t understand how aerosols work and you& #39;re not trying to.

People across the spectrum on COVID protocols are doing what feels intuitively right to them and what is emotionally preferable, but they& #39;re not basing their actions on science. This has got to stop! Evidence. Evidence. Evidence. Base actions on scientific evidence.
