On March 2, I opened up my Social Problems class to questions on the emerging coronavirus epidemic. One of the things I did was show them a graph of worldwide cases on a log scale, and told them that it implied the world would have a million cases a month later. We hit that number to the day two days ago. Here are my notes from that day:
A month later, with school indeed canceled (which I had given only a 10-20% on March 2, I recorded this 28-minute lecture for them as an update. Feel free to use any part of it any way you like*:

- At 4:40 I said of the graph shown: “The number of new cases confirmed by testing, every day, in the country, since February.” I should have said, “in the world” (as the figure is labeled).
- It’s been pointed out that social distancing and other responses to the outbreak are not the only thing that differentiate trajectories of the different outbreaks around the country. Also relevant is the demography of the area, including age, as well as health status and healthcare infrastructure. Those factors will emerge as the pandemic matures.
