Among them is Jake Rosmarin, 29, who is from Orange County and now resides in Boston. Rosmarin has been quarantining at the University of Nebraska and posted to social media about his journey.
"The repatriation flight was smooth, and I safely made it to the National Quarantine Unit in Omaha. It's been a very long few days, but hopefully I can start giving more updates again soon. A special thank you as well to University of Nebraska Medical Center and the city of Omaha for welcoming us and helping ensure we are safe and cared for," Rosmarin said on Instagram.
Rosmarin said he hadn't realized the seriousness of the situation on his cruise at first.
"For me, it just felt like weird coincidences, and honestly, I didn't think anything was wrong until we found out that it was hantavirus, and that's when I was scared," Rosmarin said. "Because, as you know, when you hear about a virus you don't really know about, you Google it, and when you Google hantavirus, it's definitely a scary virus to be seeing."
Rosmarin said that amid everything he and others have been through on board the MV Hondius, he has been able to keep in touch with his fellow passengers.
"I've messaged people and everyone seems to be in good spirits," he said.
Rosmarin said he is not experiencing any symptoms and plans on remaining in quarantine for the next 42 days.
"I think that is the best decision that's for me and for my family, and I know that here, I'm in the best care possible," Rosmarin said, adding that his room in the quarantine unit has air conditioning, an exercise bike and he is receiving at least three meals a day. "I can't ask for any more than that."
Dr. Stephen Kornfeld, who was listed in the ship residency as being from NYC, is an oncologist who lives in Bend, Oregon.
He told ABC News that he essentially took over the medical response after the ship's doctor contracted hantavirus.
"It just kind of escalated to within 24 hours after I stepped in," Dr. Kornfeld said. "One of the patients died and the other two, the physician and one of the other staff members, were getting progressively sicker, and then the first news of hantavirus came out."
The third passenger with a connection to New York State is 76-year-old Mary Roefs from Sidney, a village in Delaware County.
On Monday, 16 of the American cruise ship passengers arrived at the University of Nebraska Medical Center. Fifteen are in the quarantine unit and one person is in the biocontainment unit, officials said.
Two other passengers were flown to Emory University Hospital's Serious Communicable Diseases Unit in Atlanta. There, one person, who is symptomatic, is receiving treatment, while another is asymptomatic and under "evaluation and monitoring."
Hochul said the state is monitoring the situation, but "it's transmitted very differently than the coronavirus, there's no panic, no concern."
The governor said she is still putting together a plan to be proactive.
"This is New York, it's a large, densely populated state and city, and I just need to do the responsible thing and prepare," Hochul said.
The Andes strain of the hantavirus can spread human to human and there is no vaccine nor a cure.
Three people have died from the outbreak tied to the ship.
The CDC maintains that the risk to the general public is low.
