@JoBlakely I think they mean unlikely, rather than difficult.
@JoBlakely complete guess, as I am not familiar with hanta, bird poop. Most diseases spread by birds are spread by aerosolised bird poop, unless you eat the poop.
@JoBlakely after some very quick research, apparently the birds was a red herring.
It's rodents, and given it's a cruise ships I am not surprised, it would be weirder if it was birds.
I wouldn't worry, as cruise ships are notoriously hard to keep rodent free.
@ekg was it airborne? They are being too vague. This strain is able to be passed human to human. Even sitting next to someone on a plane.
The lack of clarity and relevant information is just infuriating.
