90-Second Read: The Hantavirus, a doomed cruise ship, and the Boston influencer who is there to chronicle it.

The Hantavirus, a doomed cruise ship, and the Boston influencer who was there to chronicle it. When Jake Rosmarin, 29, a Boston-based travel influencer, boarded the MV Hondius for a cruise from Argentina to Cape Verde he had some 29,000 followers on TikTok and 43,000 on Instagram, and eager to do his job and grow his following, he quickly got to work. In early May, after what at first seemed like the unfortunate but unrelated deaths of one, then two passengers (and eventually a third), the voyagers learned that the deaths were in fact related, and that the deadly Hantavirus was stalking the ship. On May 3, Rosmarin, a 2018 Emory University graduate who worked as a media buyer before deciding to become a content creator, put out a statement.

The isolation period was 42 days, and just as he had done at the start of the cruise, Rosmarin, lost no time posting. The snobs relish it as an opportunity to look down on "cruise people," with their love of 15-drinks-in-24-hours packages, seaborne roller coasters, and food halls so big you can get your 10,000 steps in just on your way to the sushi station. If you are in international waters on a cruise ship, no matter how powerful you are, you are still sort of stuck in the ocean. He posted videos of hourglass dolphins cresting rolling seas.

Finally, on May 10, the MV Hondius was allowed to anchor off the Canary Islands, and passengers, who likely boarded the boat with great enthusiasm, were now being greeted by people in protective gear. For their part, the "cruise people" have the relief and the joy of the bullet dodged. Those who have no position on cruises one way or the other, a minority, enjoy a disaster that is, for this moment at least, someone else's problem. But Rosmarin, who has ulcerative colitis, told me he's gotten thousands of messages, some from people who've lost a child or a partner, or who are immunocompromised.

But now he was choking back tears, a cherubic-looking young man in a baseball cap, pleading for mercy into the vastness of the Atlantic Ocean and the internet. Frazier, say, Whitney Houston's 1991 Super Bowl national anthem, or the "Game of Thrones" finale, they gleefully recall ships that were felled by norovirus, COVID, or a reef off the coast of Italy. Quickly, he would become so cozy with CNN that the first day he worked out on the stationary bike in his room, he figured its biggest star would be interested.
