Update on Hantavirus Outbreak Linked to M/V Hondius Cruise Ship

The Centers for Disease Control and Prevention (CDC) has provided a critical update regarding the ongoing hantavirus outbreak associated with the M/V Hondius cruise ship. As of May 19, 2026, public health officials are actively managing the monitoring and quarantine requirements for passengers who were recently repatriated to the United States.

Status of Repatriated Passengers

On May 18, 2026, the CDC confirmed that 18 U.S. Passengers repatriated from the M/V Hondius have been directed to remain at the Nebraska Quarantine Facility. These individuals are scheduled to stay at the facility through May 31, 2026, which marks the completion of their 21-day health monitoring period.

In addition to the passengers currently in Nebraska, the CDC has issued specific quarantine orders for two individuals. These orders were signed by the CDC’s Acting Director under the authority of the Public Health Service Act and associated federal regulations (42 CFR parts 70 and 71). Quarantine remains a vital public health tool used at the federal, state, and county levels to mitigate the spread of infectious diseases and ensure the safety of the broader community.

International Scope of the Outbreak

The situation involving the M/V Hondius extends beyond U.S. Borders. Since the passengers disembarked from the cruise ship, health authorities have identified three additional cases of hantavirus in other nations, including one case each in France, Spain, and Canada. The CDC continues to coordinate with international, state, and local health partners to harmonize monitoring efforts and implement effective strategies to protect public health.

Key Takeaways

• Monitoring Period: Repatriated U.S. Passengers are undergoing a 21-day monitoring period, concluding on May 31, 2026.
• Quarantine Measures: Federal quarantine orders have been issued for two passengers currently at the Nebraska Quarantine Facility.
• Global Impact: Aside from the U.S. Cases, hantavirus infections linked to the ship have been confirmed in France, Spain, and Canada.
• Public Health Coordination: The CDC is working across all levels of government to manage the response and ensure the safety of all involved parties.

Understanding Hantavirus

Hantaviruses are a family of viruses primarily transmitted to humans through contact with the urine, feces, or saliva of infected rodents. While the specific circumstances of the M/V Hondius outbreak are being managed by health authorities, the CDC continues to provide updates as they work to contain the risk. Public health officials emphasize that quarantine and monitoring are standard procedures used to prevent the potential transmission of infectious diseases following known exposure.

The CDC remains committed to protecting lives and livelihoods by rapidly identifying and responding to outbreaks. Further information regarding the agency’s ongoing response will be provided as the situation develops.
