Risk, hazard and mitigation with coronavirus

There is nothing more galling than learning that you had been exposed to the coronavirus weeks ago and nobody bothered to tell you (my experience today). Oh, yeah, there is, which is being exposed to this virus every day on the front lines for healthcare and customer service workers, yet being unable to get tested unless you are deathly ill….

The misleading math of rural Coronavirus

Iowa Coronavirus growth

(Note: This post has been updated from a version previously published on April 12 at Bleeding Heartland.) Fifty-one cases of COVID-19 come out of one rural nursing home in northern Florida.

COVID-19 and real-life lifeboat ethics

Before there was the “Trolley Problem,” ethics classes would commonly haul out “Lifeboat Ethics” scenarios to stimulate class discussion. In my years of teaching ethics, I never used either because I dislike them both.

Bayes Theorem

“It doesn’t want to kill you before you transmit it.” – biologist Michael Farzan of Scripps Research That quote is not so scary as it sounds; it is basic probability math. The probability math of the COVID-19 Coronavirus variant has hit the news, and not in a good way. We have already seen the first reported cases in my county… Read more »
