I'm betting that many people working in hospitals with CV patients are getting routine tests to see if anyone is catching it, regardless if they have symptoms or not.
Another thing is most health care workers who have contracted CV were most likely not wearing N95 or other correct PPE in the early days when it hid hard. Many of them catching it at work could very well be in the beginning when this was all unfolding and proper precautions weren't being used or followed correctly. It would be hard to get collect accurate data from what was going on in the beginning, but would be easier to collect data right now knowing more about CV.
Why? That's expensive. It can only cost money.
Also, incubation period makes it impossible to know where one caught it, very nearly.
It's not that expensive. ... if it was, there wouldn't have been the millions of tests already done on people. New test methods are being developed quickly. If you were working in an environment where you were surrounded by infected people don't you think it would be wise to do some routine testing on health care workers?
Maybe everyone should just ignore CV and not take any precautions and let it "do it's thing".
No, and that is why we don't do that sort of thing with healthcare workers with the one exception being TB testing, which is done yearly. You're only looking at front of the house costs.
Why dont we swab for MRSA?
Why dont we do bloodwork all the time for various bloodborne pathogens?
Why dont we...
Because it would result in massive loss of viable workforce.
If your staff is not showing symptoms, then yearly TB testing is going to be the max, if even that.
