Over a year ago I began making graphs related to the COVID-19 epidemic. It’s not controversial to identify the most basic number to tell the story: how many new cases each day, per capita? Medical personell tend to express this as cases per day per hundred thousand population, but I prefer to use cases per day per million population. Call me quirky.
I (like many before and since) decided to color-code some of my graphs, with “red” reserved for the most severe outbreaks — so many new cases each day that it will strain the health care system in a week or less, and before too long will crush it, while filling up the morgue to overflowing. I did a little research (translation: looked around on the internet, not peer-reviewed research, but at least I used “reliable” sources like Johns Hopkins Univ. School of Public Health) and concluded that since the so-called “experts” seemed to think that was 25 cases/day/100,000 people, that’s what I’d use — but I’d call it 250 cases/day/million population. Call me quirky.
