If only they'd gotten close enough to their opponents to pass something on they might have done some harm to Melbourne's flag chances.
In all seriousness, if there was a virus running through the club and it led to the club alerting the AFL, where would the Dees be in all this?
You doubt they'd be notified, but if one or two if their players are sick as a result...yeah, they'd be rightfully 'upset' to put it mildly.
