Immediate Action: Quarantine of Two Passengers
On Tuesday, U.S. health officials placed two passengers from the cruise ship MV Hondius under quarantine at the University of Nebraska Medical Center in Omaha. The orders, signed by CDC acting director Dr. Jay Bhattacharya, affect 18 passengers under evaluation, with the other 16 instructed to remain at the facility through May 31.
Outbreak Background and Context
The MV Hondius was identified as the source of a hantavirus outbreak that has sickened passengers in several ports. The World Health Organization reported 11 cases, including three deaths; the CDC confirmed eight laboratory-verified cases. The virus is the Andes strain, which normally spreads via rodent droppings but may transmit between people in rare instances.
Timeline of Key Developments
Patients were evacuated from the MV Hondius on May 6 in Praia, Cape Verde, and U.S. passengers disembarked in Tenerife on May 10. The WHO announced 11 cases and three deaths earlier in the week, and the CDC ordered quarantine of two passengers on May 19. Observation of the remaining passengers ends May 31.
Data Summary
WHO reports 11 cases and three deaths; CDC confirms eight lab-verified cases. Eighteen passengers are under assessment, two in quarantine, sixteen staying through May 31.
Official Statements and Public Health Impact
The CDC’s statement said Dr. Jay Bhattacharya signed the quarantine orders and that the measure is intended to monitor exposed individuals for symptoms. The WHO emphasized the total case count and mortality while noting that broader community exposure is unlikely. Officials also said the risk to the general public remains low, though the possibility of limited person-to-person transmission of the Andes virus justified the targeted quarantine.
Criticism and Unanswered Questions
Public health observers called the quarantine “unusual” and noted that the CDC did not explain why only two of the 18 passengers were isolated, leaving the selection criteria unclear.
Conflicting Reports and Gaps
The WHO’s 11-case count differs from the CDC’s eight laboratory-confirmed cases, showing a verification gap. The rationale for quarantining only two passengers has not been documented.

- “The orders were signed by the Centers for Disease Control and Prevention's acting director, Dr.” — CDC statement
- “The risk to the general public from the cruise ship outbreak is low, according to public health officials.” — CDC spokesperson
- “Quarantine separates and restricts the movement of people who were exposed to a contagious disease to see if they become sick.” — CDC informational release
- “It’s an unusual step and it was not clear from the CDC’s statement why only two of the 18 passengers were ordered quarantined.” — Media observation
Outlook
All 18 passengers will remain under observation at UNMC until at least the end of May. Health authorities will continue monitoring for new cases and will reassess containment measures if additional transmission evidence emerges.
