Specht is doing a lot of calculations here but I think it is a useful estimate, which fits with other guesses, that hospitals will become overwhelmed around May 8th. That helps me to think about whether to cancel non-essential travel and conferences in the next couple of months.

Yes, the contagiousness and lethality are scary:

If Specht is right that there will be 4 million cases around May 11, and the overall case-fatality rate (CFR) continues to be 2.3% (jamanetwork.com/journals/jama/…), that would be mean 92,000 of that 4 million would die.
"the estimated mean R0 ["basic reproduction number," or R0 (pronounced R-nought)] for COVID-19 is around 3.28, with a median of 2.79 and IQR of 1.16."

Here is someone who is skeptical about the continued exponential growth of the disease.

Indeed, it will not spread as quickly if people practice "social distancing."

And another description of what it is like to have hospitals overwhelmed with COVID-19:
Harvard expert: If a city in the US had a similar spread as Wuhan, it would overtake the amount of ICU beds in 45-60 days from the first case. But strict social distancing in Guangzho slowed the spread so it peaked at 19 days.
CNN poll yesterday: "57%, say they are very (18%) or somewhat (39%) confident that the government can prevent a nationwide epidemic of the virus."
