Reply #2: Remember the TV commercial for cold symptoms? You'll work with food in the grocery store

[HereSince1628]

You know the commercial that has the Sargeant tumble into the picture?
The sick woman is working in a refrigerated food section of a store...with those virus ladden hands on the top of milk jugs.

Most grocers operate under the WalMart business model...show up or get fired.
People will show up to work ready to drop over. And as the Mexican case of the story (is it verified?) about the archiologist that met Obama, you can be ill at work one day and dead the next.

The "protestant work ethic" the US is so proud of works against controlling epidemics of person-to-person transmission.
