The error bars around the numbers must be enormous. It is difficult to see how - physically speaking - they can accurately track the real numbers on the ground.
The timing seems to coincide interestingly with some companies and industries returning to work on Monday.
There is some speculation that that is because they are at their limit for how many tests they can do per day.
The test may also return a false negative. There is a case that a patient is identified after 4 tests.
That's assuming supply of testing kits is constant.
Which is a different constraint to the one in the message I was replying to.
Not just that, the hospitals are completely jammed in certain areas which means if you get the illness it's often safer to just stay at home - but then it goes unreported.
