Simpler Than it Looked
Covid-19 data for the two parallel coordinate plots below was taken from "Our World in Data” (https://ourworldindata.org/coronavirus-data-explorer) on the evenings of February 9th and December 22nd, 2021, while the line plot chronicles deaths per million through September 2nd, 2022 for seven of the 23 countries included in those parallel coordinate displays. From the leftmost parallel coordinate plot 35% of our dataset - eight of the lowest nine countries in terms of deaths per million and up to nearly two orders of magnitude less than the highest death rate - can be isolated by at least limited presence of endemic malaria or scabies and a low barrier (medical officer prescription or less) to acquisition of anti-parasitic medications. Taking this one step further using a box query reveals that the lowest seven death rates per million in our data can be perfectly explained by ready availability of anti-parasitics combined with limited hospital capacity, per the green bars of a Pareto plot superimposed on the second parallel coordinate plot. Hence, with a sample size encompassing more than a fifth of the world's population and including some of the globe's poorest nations - who apparently got off light throughout Covid - our answer to "who really killed grandma" (among many others) is apparently rigid and well-controlled medical as well as pharmaceutical systems which precluded the innovation necessary to deal with a raging pandemic.
