I'm getting questions about well-meaning medical worker threads with strict instructions on mask-wearing, implying if you don't do everything right, you endanger yourself. That advice is very true for medical workers, but it's bit of misunderstanding of universal masks. Thread

I wouldn’t either. The first time I saw a slow motion video of a sneeze changed my behavior forever.https://www.youtube.com/watch?v=bFxgVkslD-k …

That's an amazing video! It's also an amazing evolutionary story—these little not-even-alive things make us expel them so effectively that they can thus hijack other people's cells to make them sneeze to spread further.

Good to explore but if there was such sustained transmission *outdoors*, we would be looking at very very different numbers. That's relevant for ventilation systems in hospitals (closed ventilation/high dose due to concentration of sick people). Not true in a running trail.

Are you really qualified to give advice at this level of granularity?

I thought some preprints suggested it is effectively aerosolized? a. https://www.statnews.com/2020/03/16/coronavirus-can-become-aerosol-doesnt-mean-doomed/ … b. https://www.livescience.com/coronavirus-can-spread-as-an-aerosol.html … (haven't evaluated these preprints closely but will do so tonight, just sharing for consideration)

It's something to watch, for sure! But it's attack rate is nothing like, say measles. Personally, I'd feel fine running, say, twelve feet behind another runner. (Twice the six-feet recommendation because running is faster than walking).
