The flu kills between 35 and 75 thousand each year. We have a vaccine and treatments for the flu. I suppose it could be a lot worse without those tools.70,000 cases, 4800 deaths. Isn’t the flu worse?
And these^^^^ are just the types of very important factoids that do not get properly communicated to the masses, and their exclusion totally mishapes, for the worse, the public's understanding of X. There are many of these types of crucial details not being reported properly and not being understood by the average person whose views and understanding are shaped almost entirely by mainstream media (whatever that is these days).They are only testing people who go to the hospital

I'm a high school math teacher. And yes, I see math-related incompetence everywhere. I had to tell my financial adviser that a maximum (usually) occurs when the first derivative equals zero, and had to show him how to use the quadratic formula. He makes at least twice what I do.Ajp,
You just qualified to be CEO o MD Anderson because obviously you are much smarter than anyone at Catholic Healthcare Incompetence

I've never understood people who are proud of being a jerk in public. Can you explain the thought process?My reply - "Senator, show me a politician I have an ounce of respect for, and I'll show you a dead man." Then I exploded while he broke his gavel.

Good post, Acho.While the total number of cases and deaths doesn't sound compelling, anyone with a good understanding of math will tell you those aren't the important numbers. The most important number is the rate of growth.
Covid-19 has consistently had a daily growth rate of 15-25%. In other words, the amount of cases each day is roughly 20% more than the number of cases the day before. That's not steady growth; that's exponential growth.
One of the best ways to understand exponential growth is to look at the doubling time (or in the case of decay, the half-life). You get that with:
ln(2) / (rate)
where rate is expressed as a decimal (in our case, 0.2).
For a shorthand you can do in your head, use:
70/(rate)
where rate is expressed as a percentage (in our case, use 20). This easier mental math version has an error of less than 1%.
With a growth rate of 20%, that gives us a doubling time of roughly 3.5 days. Every week, the number of people with coronavirus quadruples. That's been going on for months now.
At the time of this post, Italy has roughly 15,000 confirmed cases, and the US has just over 1,200. That makes it sound like we're doing 10 times better, but at current rates of growth, we'll have as many cases as Italy in roughly 12.6 days. Three weeks after that, the US will hit 1 million cases.
In reality, exponential growth can't go on forever - if it did, the number of cases would eventually exceed the population of Earth. A few different factors can slow down the rate of growth:
1. Stop exposing people to each other (no travel or crowds)
2. Wash your hands
3. Once everyone's sick, you can't have more new cases!
Most of the time, exponential functions will usually reveal themselves to be the beginning of a logistic function (an S-curve). But since the number of new cases each day is still greater than the number of new cases the day before, we still haven't hit the inflection point. Once you hit that point, it means you can usually count on topping out at around twice the value you currently have. But since we haven't made it there yet, we should assume there will easily be more than twice as many new cases before it's over. As of yet, there's no sign there won't be orders of magnitude more cases.
Short version: If you're only paying attention to total quantity, and not rate of growth, you're paying attention to the wrong numbers.
Typically that percentage is based on number of infected to the number of deaths of those infected.Is that figure the percentage of deaths among the reported/confirmed number of actual cases or of the total population of Germany? Germany has a total population of 83 million. If it kills off 0.2% of the population, that would be about 166,000 dead. The US has a population estimated of 330,000,000, so 0.2% death rate would be 660,000 folks.
I hope — but also predict — that you’re mistaken.There's no way that there will be a 2020 football season. The virus will still be an issue in September.![]()
Along those lines, here's an article at the NYTimes about the growth factor and including interactive charts where you can adjust the timing of the intervention and the level of aggressiveness for the intervention.While the total number of cases and deaths doesn't sound compelling, anyone with a good understanding of math will tell you those aren't the important numbers.

Probably will be a radically different format than in previous years ...Has the Longhorns spring training/game been canceled?
