A BCG Chart Can Tell You What’s Safe and What’s Not

What’s dangerous and what isn’t? Erin Bromage, a professor of biology at the University of Massachusetts Dartmouth, has a pretty useful roundup here. The main lesson is: it’s all about Volume x Time. That is, it’s dangerous to be in places with a large volume of viral particles and it’s also dangerous to be in places that might have low volumes but require you to stay a long time. As a former management dweeb, I immediately had to put this into BCG chart form:

Supermarkets, Bromage says, are generally fairly low in viral particles; aren’t very crowded; and usually require only 30-60 minutes of your time. They’re pretty safe. Conversely, a public toilet requires only a few minutes of your time but is shockingly high in viral particles if an infected person has been in it recently.

Indoor workplaces mostly have fairly modest volumes of viral particles, with obvious exceptions like meatpacking plants. However, you’re there eight hours a day. If anyone is infected, there’s a decent chance you will be too. And then there are restaurants, which can have quite high viral loads and often take 2-3 hours of your time.

Anyway, read the whole thing. “The main sources for infection,” Bromage says, “are home, workplace, public transport, social gatherings, and restaurants. This accounts for 90% of all transmission events.” The rest of the piece is pretty helpful too.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
