Coming In From the Edges
It's interesting to see the virus come into the country via its borders first. That's what you would expect, I guess, and entry via major airline hubs like LA, Chicago and New York. The little bugger is predictable in many respects, and yet it seems there's little we can do to stop it. I guess that's a big part of why it's scary.

You have a hotspot in Washington state, perhaps 1500 cases.

If there are only 18 confirmed cases in the state, does it mean that the other 1482 people are asymptomatic? If so, maybe the virus isn't all that bad?
It could be lower or higher depending on a lot of assumptions.
Worldwide, death rate is settling around 1%. Then 4 deaths implies 400 cases.
If the hotspot centres around care homes, then it is a particularly vulnerable group and the total cases might be lower again.
If the care home group was infected from visitors, then it might be much larger.
The nightmare for an analyst is that at this stage the data is changing from day to day and it is hard to do the maths on the hoof. Much easier in retrospect.
Eighteen confirmed cases and four deaths is a mortality of 22%. Not credible, based on mortality elsewhere.
Either something is massively amplifying the death rate of the are a lot of unconfirmed cases in the area.
L: or it could mean those 1482 people either haven't had serious symptoms, or any, or haven't been tested. I'm assuming it's a number spit out by some epidemiologist's model.
EM: this page shows a latest death rate of about 3.3%:

But this may be an overestimate if a lot of people have little-to-no symptoms, or haven't gotten tested, or (as in China) been rejected by all the hospitals they visited and sent home to suffer and die.
And perhaps the latency period of the virus -- the time between someone is exposed to when they start to show symptoms, ~ weeks(?) -- is quite a complicating factor that might be difficult to include in models -- since no one really knows what this latency period is.
Some new info:
"WHO estimates coronavirus death rate at 3.4 percent — higher than earlier estimates," WaPo 3/3/20.

If half the people in the US get the virus, that would mean almost 6 M dead. Impossible to fathom.
