That exponential growth. It is amazing to think that the numbers have grown so much that even the most pessimistic number of 10k hidden cases in the US (since we don't test) -- using that number only pushes us out a day globally and not even much locally.

For all intents and purposes then, globally we're on a very aggressive path that's going to be almost impossible to stop.

But if you've been following Wuhan, Italy, Iran -- you already know this.

Please remember that epidemics must, by rules of reality, logistic curves, not exponential.

Yes at some point the new infections has to go down if for no other reason than there is no one left to infect. As you said it must be logistic, because after a while infected people simply bump into fewer and fewer uninfected people.

Thanks, I was wondering what the name of the curve was, because logically there is no way it ends up being totally exponential.

And to be more specific, you can roughly model it with a Gompertz function: https://en.wikipedia.org/wiki/Gompertz_function

Stops in May because the planetary population is less than the next doubling.

This model indicates a few percent drop in the worlds population by summer.

Yes but by then the whole population of THE WORLD is projected as infected.

It's a tiny bit silly, this is not what happened in China, it's not what will happen in many places. It may be what happens in the US thou...

yeah china (after they quit pretending it didn't exist) actually started to quarantine people an mean it, not just pretend its the flu an refuse to test people because it might make the official numbers go up.
