Attending an academic conference soon?
Going by reports and polls on Twitter, you probably have a 10-20% chance of getting #COVID19 there.
Here's a small thread with some evidence and some suggestions. 1/
2/ ACM #SIGGRAPH, a major conference and trade fair with up to 20,000 attendees, will take place in Vancouver next month, right in time for the peak of a COVID wave.
That means that probably 2000 people will return home infected with COVID.
3/ Of these 2000 people with COVID, a few hundred people will be knocked out for a few days or weeks.
About 1% might suffer from *debilitating* #LongCOVID effects - i.e. 20 attendees will suffer from a major illness for weeks or months or more.

Earlier this month, I traveled by air for the first time during the pandemic.

Even though I'm "healthy" by all accounts, I live with at least one highly vulnerable person, and it's very important to me to not bring #covid into my house.

Here's what I've learned since. 🧵

First: if you're someone who cares about #covid safety, you will wear a mask every time you're indoors, period.

But not all masks are equal, and not all indoor environments are equally safe/dangerous.

I know you know this, but I'm going to go in depth here. Hang tight!

(2/n)
For most indoor spaces, wearing a well-fitting, NIOSH certified N95 mask is totally sufficient.

Note that I said "N95" and not KF94 or KN95.

The horizontal straps create far fewer air pockets than over-the-ear straps do, and fit more people far better.

Heads > ears.

Mariner 2 / Venera 14 showed an inhospitable surface on Venus — 900 degrees Fahrenheit! thought to be a "runaway greenhouse"
but -- some people think microorganisms (remnants of a biosphere on the surface) could have taken refuge in the clouds of Venus after the surface was "baked"
