US passengers of hantavirus cruise ship being monitored in Nebraska

May 12, 2026

Eighteen Americans evacuated from the cruise ship MV Hondius due to potential hantavirus exposure are under medical observation at specialized facilities in Nebraska and Atlanta. The vessel, carrying approximately 150 passengers from Spain's Canary Islands, has been linked to nine confirmed hantavirus cases and three deaths globally. Among the evacuated Americans, one person tested positive without showing symptoms while another exhibits mild signs of illness, though health officials emphasize the public risk remains extremely low.

Who is affected

18 American passengers evacuated from the cruise ship (16 in Nebraska, 2 in Atlanta)
One American passenger who tested positive without symptoms
One American passenger showing mild symptoms and their partner (both in Atlanta)
A British-US dual national in quarantine in Nebraska
Two California residents being monitored in Nebraska
Two California residents who returned to the state without symptoms
Six Canadian passengers (four in British Columbia/Yukon, two in Ontario)
Two British nationals being treated in the Netherlands and South Africa
Approximately 150 total passengers aboard the MV Hondius
Three deceased individuals from the outbreak

What action is being taken

Health officials are closely monitoring the 18 evacuated Americans at facilities in Nebraska and Atlanta
The 16 passengers in Nebraska are undergoing symptom monitoring and assessment
The symptomatic passenger has been placed in a biocontainment facility
Canadian passengers are self-isolating for at least 21 days (potentially extending to 42 days)
Two Ontario residents are self-isolating at their home

Why it matters

This situation is significant because it involves the Andes strain of hantavirus, which is unusual among hantavirus variants in that it can spread from person to person through prolonged close contact with symptomatic individuals. The outbreak has already resulted in three deaths and nine confirmed cases worldwide, demonstrating the virus's potential severity. The deployment of America's only national quarantine unit and biocontainment facilities reflects the seriousness with which health authorities are treating this situation, even though officials emphasize the risk to the general public remains very low due to the virus's limited transmissibility.

What's next

Passengers in Nebraska will undergo further assessment after rest and sleep
Passengers are expected to remain at the Nebraska facility for assessment over the next several days
Officials will determine on a case-by-case basis whether passengers need to complete the full 42-day quarantine period
Canadian self-isolation periods may be extended from 21 to 42 days depending on circumstances
