"if they were aware that a person could or would, pose a risk"
Not an issue here apparently - the doctor claimed he wasn't aware ogf the patient's occupation; in which case, is it his job to find out and pass on the information (assuming, of course, he was qualified to assess that this person was a risk - he was a general practitioner, wasn't he)
What you appear to be saying is all this patient confidentiality nonsense is just that - nonsense - and anybody in receipt of such information is duty bound to pass it on to whoever he sees fit?
Do I have that right?
