The isolation period has concluded for the group of 18 Americans, formerly passengers aboard the MV Hondius, who were potentially exposed to hantavirus over a month prior.
The mandated 42-day observation period concluded on June 21, and health authorities have reported “no sustained transmission” of the virus within the United States, as communicated by an official from the Department of Health and Human Services (HHS) to ABC News.
Of the 18 individuals, six remained at the National Quarantine Unit (NQU) in Nebraska for the duration of their observation, while others were permitted to depart at different intervals over recent weeks, contingent on their respective states’ capacity to implement effective public health containment measures.
“This endeavor, under the direction of President Trump and Secretary Kennedy, showcased the efficacy of synchronized public health initiatives,” stated the HHS representative. “Through robust cooperation amongst federal, state, and local entities, HHS played a vital role in safeguarding the American populace, mitigating potential hazards, and bringing this response operation to a successful resolution.”
One of the individuals under quarantine, Jake Rosmarin, shared a video on Instagram illustrating a countdown timer reaching zero, after which he became emotional. Rosmarin noted that the NQU staff had set up the countdown timer for those confined at the facility.

He mentioned that his group was invited to take a tour of the facility upon their release from quarantine and subsequently shared a meal with the personnel.
“For the first time in 42 days, I experienced being outdoors without a mask,” he conveyed in another photograph posted on Instagram.
Rosmarin, who was traveling alone on the vessel, had previously informed ABC News of his intention to remain at the Nebraska facility for the entire 42-day duration. He cited the facility’s prompt access to medical attention and twice-weekly testing as key reasons for his decision.
The World Health Organization (WHO) reported receiving an alert on May 2 concerning a cluster of “severe acute respiratory illness” cases onboard the MV Hondius, which included two fatalities and one passenger in critical condition.
As of May 27, a total of 13 hantavirus cases – comprising 11 confirmed and two probable instances – and three deaths, of which two are confirmed, have been documented, according to the WHO. All affected individuals were either passengers or crew members on the ship.
The prevailing theory regarding the cluster of cases suggests that the initial infection occurred on land, prior to the individual boarding the cruise ship, the WHO indicated.
The 11 confirmed cases yielded positive results for the Andes virus, a seldom-seen strain of hantavirus that is recognized as the sole variant capable of human-to-human transmission, as per the Centers for Disease Control and Prevention.
