What happens when employees start to sue their jobs (if they have an outbreak)?
The insurance industry is in straight panic mode about all of this, but for a number of reasons. WalMart's wrongful death lawsuit is just the beginning. You'll see suits against boards of directors for shareholder performance, overall response to the pandemic, worker safety/negligence, etc.
Something larger is on the horizon too with businesses shutting down and lack of coverage for "interruption." Estimates for this are upwards of $300 billion monthly, but it's something that isn't typically covered. However, if being forced to pay, say by litigation or jury, this could potentially liquidate obscene amounts of Property & Casualty insurance companies and the industry would nearly fold.
9-11 changed the game with Terrorism coverage funded through a government program (war is typically excluded in coverage). I think we'll see something along these lines come out of this as well for pandemics/disease.
