Legally they cannot. The ship has no authority to hold her and while US authorities could detain her or send her to a quarantine location they can't deny entry.

I mean he can't say, and it would be irresponsible for him to speculate, because there isn't enough scientific data to say what effect it has.

Just a note for clarification, there is no leprosy in Hawaii. Kalaupapa is a former leper colony that is now a national park which educates people about the disease and the people who were forced to live in isolation there. While some of the descendants of those who were sent to Kalaupapa, or family who went with them, still live there as that's where they were born and grew up and it's their home, no one there has leprosy and no one with leprosy would be sent there now.

Under ordinary circumstances this is true, this is much less true when everyone and their uncle is contacting everyone even remotely govt affiliated about unemployment delays, stimulus checks and complaints about lockdown and lockdown violations.

Did you ask the LAPD or CBP to force the ship to allow you to disembark? You really should have, as legally they were violating the law by keeping you onboard.

Which means that you have grounds to sue not just the company but the US govt.
