WASHINGTON, D.C. — The U.S. Department of Health and Human Services has concluded its public health response to a Hantavirus exposure event linked to the M/V Hondius cruise ship after a 42-day monitoring period ended with no additional cases or sustained transmission identified in the United States.
Federal officials said no individuals in the United States remain under public health monitoring related to the incident, marking the end of the domestic response effort.
The exposure event prompted a multiagency response involving HHS, the Centers for Disease Control and Prevention, the Administration for Strategic Preparedness and Response, the U.S. Department of State and state and local health departments.
According to HHS, agencies worked to identify potentially exposed individuals, conduct medical monitoring, provide clinical guidance and prepare healthcare systems for a potential outbreak.
To support the response, HHS issued a declaration under the Public Readiness and Emergency Preparedness Act, a legal mechanism intended to facilitate the development, distribution and administration of medical countermeasures and support research efforts involving investigational treatments.
Federal agencies also coordinated with foreign governments on traveler communications, repatriation planning, contact tracing and healthcare preparedness measures.
“Protecting the health and safety of the American people is our highest responsibility,” HHS Secretary Robert F. Kennedy Jr. stated. He added that the department moved quickly to identify potential exposures and support state and local health officials, resulting in no sustained Hantavirus transmission in the United States.
CDC Acting Director Jay Bhattacharya described the outcome as evidence of the value of coordinated responses to infectious disease threats originating outside U.S. borders.
“As a result, we prevented any new cases from arising in the U.S.,” Bhattacharya stated.
Hantaviruses are primarily spread through contact with infected rodents or their droppings and can cause severe respiratory illness in humans. Person-to-person transmission is considered rare and depends on the specific virus strain.
Federal officials characterized the conclusion of the monitoring period as a significant milestone in the response effort and indicated that all activities related to the M/V Hondius exposure event have been completed.
