Unless Google has a spectacularly ineffective workplace rumor mill, or whatever the right term is in a situation like this, I'm pretty sure everyone knows the person affected even if they haven't been officially told.

Or they may have told the affected folks without telling the press. That would be a reasonable compromise.

No - because I know people in this office and they have not told them anything. They didn't even announce it until AFTER work on Friday.

You mean, you know people who you know to have been exposed to the person who was infected? Are you certain that they were in the same building at the same time? If not it's not really a defeater to my hypothesis. If your friends were not exposed to the infected individual they would not have been notified.

Admittedly the scenario I'm proposing seems unlikely. Seems they would have at least mentioned it if they were going to tell the folks who might have had contact with the individual. However. I'm leery of jumping to conclusions.

Can you share the specific office building? So I could at least notify my friends who work in Google Zurich if they are affected.
