WASHINGTON — A United States citizen aboard a government-chartered repatriation flight has tested positive for hantavirus, federal health officials confirmed, prompting authorities to launch contact tracing efforts and monitor fellow passengers for potential exposure.
The case came to light after the individual, whose identity was not disclosed, was screened upon arrival following the repatriation flight. Officials did not immediately reveal the passenger’s country of origin or the specific strain of hantavirus detected, though the disease is most commonly contracted through contact with infected rodents or their droppings and is not typically transmitted from person to person.
The Centers for Disease Control and Prevention said it was working with state and local health departments to identify and notify individuals who may have been in close contact with the infected passenger during the flight. Authorities stressed that the risk of transmission among fellow travelers was considered low, given the virus’s known routes of infection.
Hantavirus pulmonary syndrome, the most severe form of the disease in the Americas, carries a fatality rate of approximately 38 percent, according to the CDC. Symptoms typically include fever, muscle aches, and fatigue in the early stages, progressing to severe respiratory distress as the illness advances. There is currently no specific antiviral treatment approved for the disease.
Health officials urged anyone who had traveled on the flight and was experiencing symptoms consistent with hantavirus infection to seek medical attention immediately and inform their healthcare provider of the potential exposure.
The repatriation flight was part of ongoing U.S. government efforts to return American citizens stranded abroad. Officials declined to specify the flight’s origin, citing privacy concerns related to the patient’s case.
The incident has drawn renewed attention to the challenges of managing rare but potentially deadly infectious diseases within the context of international air travel and large-scale repatriation operations.
The CDC and the Department of Homeland Security did not immediately respond to requests for further comment.
