Hantavirus Incubation Period Raises Concerns After Cruise Ship Evacuation

Seventeen Americans and a dual U.S.-British citizen have returned to the United States after being evacuated from a cruise ship at the center of a hantavirus outbreak. Officials expressed concern about the virus's incubation period as they monitor those who were on board.

The group arrived back in the U.S. following the evacuation prompted by the deadly outbreak. Health authorities are tracking potential cases among the returned passengers and crew.

Officials are focused on the hantavirus incubation period because symptoms may not appear immediately after exposure. This delay complicates efforts to determine who may have been infected during the voyage. The virus can cause serious illness, and monitoring continues for anyone who spent time on the affected ship.

Authorities have not released details on the total number of confirmed cases or additional evacuations. CBS News chief medical correspondent Dr. Jon LaPook reported on the latest developments surrounding the outbreak and the return of the passengers.

The situation remains under review as officials assess the risk to public health from the returned individuals.
