Update: A new iteration is now available:
My morning ritual for the past week has been to update my COVID-19 spreadsheet and ponder my chart. Here’s the latest:
On the one hand, if you compare it to last week’s chart, it’s not a happy result for those of us in the U.S. (Italy’s curve might be flattening. We’ll see next week.) On the other hand, remember that this is a lagging indicator. This past week’s line was essentially pre-determined by what happened the previous week. Earlier this week, the Bay Area instituted shelter-in-place. Shortly thereafter, California made it state-wide, and New York and Illinois followed suit after that. We’ll see if this has any noticeable impact next week.
I made one slight tweak to the graph (adding labels to the axes; thanks to Kate Wing for the gentle scolding). I’d like to change the gridlines on the x-axis to every seven days, but can’t do that in Google Sheets. Not a huge deal. I’d also like to experiment with a log 2 graph (versus log 10) on the y-axis to more easily show how many days it takes for new cases to double, but again, can’t do that from Google Sheets. Again, not a big deal. I’d also like to do a region-by-region analysis, as suggested by many others and made possible by David Janes’ data, but haven’t gotten around to that yet.
I started doing all of this as an exercise in self-care. I wanted to understand what was happening, and I found what I was reading to be not just largely unhelpful, but actually debilitating. This has helped a lot. There is something very calming about looking up numbers, plugging them into a spreadsheet, and pondering the results, even if the results aren’t very good. (Come to think of it, this also played a huge role in helping me achieve better work-life balance, so it might be a pattern.) I haven’t been able to avoid the media as much as I hoped, but it’s helped me make sense of what I’m seeing and ignore articles and missives that are generally unhelpful or worse. It’s also validating when folks who understand this stuff far better than me are coming to similar conclusions.
I’ve loved seeing friends and others play with the data as well. One of the best websites I’ve seen is Covid Act Now, which shows state-by-state projections based on hospital capacity and what we understand about different interventions. They’ve also shared their model openly, and they’re posting the right disclaimers. (Good rule of thumb: Be skeptical of anyone who claims certainty about their conclusions unless they’re an epidemiologist, and even then, take everything with a grain of salt.)
I’m also inspired by everyone working on the front lines — from health care workers to domestic workers — and to those who are doing their part to support those who are. (Hat tip to Jon Stahl for sharing the amazing work that Carl Coryell-Martin instigated, for example.) Stay safe everyone, stay at home if you can, and be well.

Hi Eugene: Thought might be interested in this analysis. Seems like we need to institute draconian policies now to avert a total disaster but the leaders in the US and UK (wonder why those politicians?) seem incapable of taking the tough choice. https://medium.com/@tomaspueyo/coronavirus-the-hammer-and-the-dance-be9337092b56
Hi Angus! Yes, I’ve read both Pueyo pieces, and I cited the first piece in my initial analysis: http://eekim.com/2020/03/making-sense-of-covid-19-and-trying-to-stay-calm/
I agree, we need more draconian policies sooner rather than later. Thank goodness for local government. In the U.S., I think California and Illinois are in the best possible shape thanks to acting early. There’s a decent chance that we’ll have started flattening the curve in another two weeks, at which point enough more testing will hopefully be available, which will allow us to do more targeted quarantining. I don’t understand why Jay Inslee hasn’t instituted shelter-in-place in Washington yet. They are in dire straits right now.
Hope you and yours are staying safe and sane.
