RT’s Three Key Takeaways:

  1. Response Conclusion: The Department of Health and Human Services (HHS) ended the 42-day monitoring period for Hantavirus exposure related to the M/V Hondius cruise ship on June 21, 2026.
  2. Public Health Coordination: Federal agencies, including the Centers for Disease Control and Prevention (CDC) and the Administration for Strategic Preparedness and Response (ASPR), collaborated with state and local partners to provide clinical guidance and healthcare system readiness.
  3. Emergency Declarations: A Public Readiness and Emergency Preparedness (PREP) Act declaration was issued to facilitate the development and distribution of medical countermeasures during the response effort.


The US Department of Health and Human Services (HHS) announced the successful conclusion of the federal public health response to a Hantavirus exposure event linked to the M/V Hondius cruise ship, according to the agency. The final 42-day monitoring period ended on June 21, and no individuals in the US remain under observation for the virus.

Under the leadership of HHS, federal, state, and local partners worked to identify exposed individuals, conduct monitoring, and ensure healthcare system readiness. “HHS moved swiftly to identify potential exposures, support state and local health officials, and prepare our healthcare system to respond,” said Robert F Kennedy Jr, secretary of HHS, in a news release. As a result of these efforts, HHS reported that no sustained transmission of Hantavirus occurred in the US.

To support the effort, HHS issued a Public Readiness and Emergency Preparedness (PREP) Act declaration. This facilitated the development and administration of medical countermeasures and accelerated research while investigational treatments were evaluated under federal oversight, according to the news release. The CDC and the Administration for Strategic Preparedness and Response (ASPR) coordinated healthcare preparedness, traveler communications, contact tracing, and medical monitoring.

The conclusion of the monitoring period involved coordination between the White House, the CDC, the US Department of State, state and local health departments, healthcare providers, and other public health partners. “The successful conclusion of this response demonstrates the strength of a coordinated response to infectious disease threats that occur outside of our borders,” said Jay Bhattacharya, acting director of the CDC, in a news release.
