ok, so you go on a cruise, get infected by overseas bugs and then come back to OZ, bleating that you are super human because you do not have the typical symptoms personally.

have you ever considered that you are still a 'carrier', regardless of your mute reaction to the bugs?
in other words, people who come back from cruises should be at least isolated in quarantine until we can get a 'germ' scan and risk assessment back to the community.

ps- i hope you do not only wear rubber gloves, but breathing apparatus would be a gesture of goodwill on your escapades to busy shopping centres.
