WASHINGTON, May 14 - The U.S. Centers for Disease Control and Prevention reported on Thursday that 41 people in the United States are currently under monitoring for possible hantavirus exposure. Health officials said the majority of those monitored should remain at home and avoid contact with others throughout the 42-day monitoring period.
Dr. David Fitter, who is serving as the incident manager for the CDC's hantavirus response, described the composition of the group of 41 during a media call. He broke the population into three distinct categories:
- Repatriated passengers - individuals who were recently returned to the United States and are now located in Nebraska and at Emory.
- Passengers who had already disembarked - those who left the ship and had gone back to their homes before the outbreak was identified.
- Possible travel-related exposures - people who may have been exposed while traveling, particularly on flights where a symptomatic case was present.
"First, passengers who were recently repatriated and are now in Nebraska and Emory. Second, passengers who had already left the ship and had already returned home before the outbreak was identified. And third, people who may have been exposed during travel, specifically on flights where a symptomatic case was present," Fitter said on the call.
The guidance issued by the CDC emphasizes that most of the monitored individuals should stay at home and avoid interactions with others for the full 42-day observation period. The agency did not provide additional case counts or new clinical details beyond the size and makeup of the monitored population and the recommended precautions.
The CDC's characterization of the monitored group highlights travel and repatriation as central to the agency's response framing. Officials are tracking people across several settings - designated care locations in Nebraska and Emory, private residences of passengers who had already returned home, and transit settings such as commercial flights where exposure may have occurred.
Beyond the numerical update, the CDC's public comments on Thursday focused on identifying who is being followed and where they are located rather than on specific clinical trajectories or projected outcomes. The 42-day monitoring window and the instruction for many monitored individuals to avoid contact with others remain the principal operational guidance announced by the agency.
