Outbreaks are rare because hantavirus[0] comes from rodents, so you might be unlucky and get it - but you can't share it with others.

There is, however, one far more dangerous form.. called Andes Virus[1] (notice where the ship started its journey) Andes-hanta can be spread person-to-person. Dangerous in close-quarters, probably a bad region to start a cruise from.

I think the key is close quarters transmission is required for ANDV. It requires people to share a bed or have close proximity. This is primarily a threat to family members which means it is much easier to contain than say COVID. This should in theory be easier to track and isolate than monkey-pox. It could however be a threat to other people in a hospital so they may have to dedicate a wing of a hospital to these people. They would know who was on the ship and could follow their path. I am not suggesting it is not a threat but I think it's being blown out of proportion.

It is much worse than that - not airborne, but touching the same surfaces: KLM flight attendant hospitalized after contact with hantavirus (33 points, 13 hours ago, 22 comments) https://news.ycombinator.com/item?id=48048121

I think that aligns with what I said. It's a path that can be traced. Not a fun exercise by any means but I think it's doable by the CDC. They and the WHO train for this all the time.

It can be traced as well as airborne? Not easily, not perfectly. One attendant (so far) - they didn't even know she was sick at the time (long gestation). Not whomever cleaned the plane later, took the seat beside hers, checked her boarding pass, checked/retrieved her luggage, used the pass-printing machine right after her, got in the same cab she took to the airport as she got out, held the same escalator railing, held the same transit bar, pressed the same open door buttons, used the same cubicle in the washroom.

		It can be traced as well as airborne? I believe so, yes. AFAIK it is only transmissible via the airborne vector from rodents to humans. Human to human requires physical contact based on my limited reading on the topic.
