The Imperial College in London (one of the most prestigious institutions in the world) initially suggested the best approach was to allow herd immunity and isolate high-risk individuals selectively. Then they came back with a model that basically said there would be 2.2 million dead in the U.S. and 500,000 dead in the UK if no action were taken to slow the virus. This model and report largely fueled the hysteria we currently see. Last Thursday, they drastically downgraded their projection to less than 20,000 deaths in the UK. Part of the reason for the downgrade is that a study out of Oxford (another prestigious institution) said that only 0.01 percent (1 out of 10,000) that contract the virus will need hospitalization. Another reason is we just aren’t seeing such horrific outcomes.
It’s important to note that when any “new” disease comes along the mortality (death) rate is
always overestimated for several months at a minimum. The reason for this is that the actual number of deaths (the numerator) is known to a high degree of confidence. The number of people infected (the denominator) is grossly underestimated, since 90–95 percent of cases are mild and most people are never tested. For example, if 10 people die and 100 people test positive, then it’s a 10-percent mortality rate. But if the actual number of people who were positive was 2,000, then the mortality rate is only 0.5 percent.
Clearly while one is going through a unique event,
no one really knows exactly how it will play out. But if we depend more on real numbers and historical events, as opposed to models (no matter how well designed) that depend on numerous assumptions and operator biases, we will make better decisions.
We also can gain perspective by real historical data that we can all relate to. Consider the following:
• As of 3/27/20 at 1 p.m., there have been 26,448 deaths and 577,660 cases worldwide.
• As of 3/27/20 at 1 p.m., there have been 1,429 deaths and 94,425 cases in the U.S.; that means the
overestimated death rate in the U.S. is 1.5 percent, and the actual one will be much lower.
• In New York (greatest number of cases in the U.S.) the death rate is 1.1 percent.
• Per the CDC, the 2017–18 flu hospitalized 810,000 and killed 61,000 in the U.S. (that’s 42.7 times more than the coronavirus has currently killed)
and people argue over getting vaccinated.
• Per the
Lancet, Dec. 13, 2019, the flu kills 291,000–646,000 per year worldwide.
• In 2017, malaria killed 435,000 worldwide.
• Per the CDC, smoking in the U.S. killed 480,000 last year, 41,000 by secondhand smoke.
• Per the CDC, alcohol in the U.S. killed 88,000 every year between the years 2006–10.
• Per the CDC, the Swine Flu of 2009–10 killed between 151,700 and 575,400 worldwide.
• Per the CDC, the Swine Flu of 2009–10 infected 60.8 million, hospitalized 273,304, and killed 12,469 in the United States.
• Per the CDC, last year 19,510 people were murdered in the U.S., 47,173 committed suicide, and 40,992 died from sepsis.
• 38,800 in the U.S. died in traffic accidents last year.

I acknowledge that the coronavirus is serious, especially for those in the high-risk categories, and we don’t know exactly how it will play out. It does appear though in the overall scheme of things that we’re overreacting a bit. Actually, IMHO more than a little bit.
