What, in any sense of the imagination, would have made this a good story to fake? It is a s**te story, as you said, but that is because it is based on very little information from an email sent to Civ Eng Staff and Students from Occupational Health. If I find out anymore I'll update it.
If I was going to fake stories (and trust me, I don't have the time or imagination and there is plenty of other stuff going on not to need to) I would spend more than five minutes writing it and I would ensure it was on something a bit more exciting. 'Someone got ill but they're better now, and we don't think they passed it on to anyone' is hardly sensationalist is it?
