I live in Canada. We see these 'Hepatitis vaccine' posters at every doctors office/clinc. They are all related to "going on vacation somewhere warm".
So the implication is "Caribbean vacation = hepatitis".
There were even TV commercials that tried to show "unexpected places you could get hepatitis from", from the ice-cube, from the sand on the beach (showing a cut foot), from a nail salon, etc. Just to try and raise awareness.
