These people certainly have more exposure to other humans than most people do. But not so much that they should be making up whole percentages of the infected population. I believe they are just well connected and wealthy and it's easier for them to get tested.
You can't have confirmed cases without testing. I've come to believe these confirmed case numbers may be having a negative effect on our understanding of the situation.
One side: it's much more widespread than we realize.
Other side: it's much more mild and less fatal than we first thought.
That's all you need tk knoe.
The first tested case. Given the delay between onset and diagnosis, + amounts of tests being actually done, + the couple days you mention, you may as well have over a thousand infected people in your city now, and you won't know until a) more tests start being made, or b) some of these people will start getting hospitalized in the next couple of days.
Do you not trust them the employees to work their part on their own?
Move your employees to WFH now.
Ensure you all have the infrastructure at home to support being as effective as possible.
If other companies did nothing, then you would do nothing.
Interesting. Entrepreneurs are usually way more forward thinking.
