I've been plotting Wisconsin's covid data since March 2020. The plot I find notable right now is my plot of the two week rolling average of the two week percent growth. It's basically the rate of change of infections. The previous highest value was 6.2%, literally the first day on my plot, April 11, 2020. That was broken Tuesday, and yesterday is at 7.1%. During the lead up to our biggest infection spike the growth peaked at +5.2%.
Eh. Case counts are super low right now so percentages get artificially high. The change on 10 to 11 is a 10% increase but 1000 to 1080 is only 8%. I'd take the 10% change there every day. Thing are going up, without question. But sometimes it can be better to look at raw numbers over percents. A lot of epidemiologists use cases/100,000 in the US or cases per 1,00,000 elsewhere as it gives a more accurate representation of things.
