WASHINGTON — Officials from the Centers for Disease Control and Prevention said Wednesday the risk of a member of the general public contracting hantavirus remains low despite several passengers on a cruise ship becoming infected with the disease.
Dr. Brendan Jackson, an epidemiologist and the agency’s team lead in Nebraska, said Americans who were on the MV Hondius cruise ship after others were diagnosed with the illness were flown to the National Quarantine Center at the University of Nebraska Medical Center.
Healthcare providers at the site have been talking with each passenger about whether they may have been exposed to any of the people with confirmed cases. They’re also monitoring the Americans for fevers or other symptoms.
“This particular virus has a long incubation period, so the monitoring period is 42 days,” Jackson said. “And the 42 days started with the departure of the ship, so May 11 was day one.”
Any cruise ship passengers who traveled on commercial flights, leading to possible exposures for others on those planes, left the ship before the infections were diagnosed, he said.
“The passengers that are being monitored who were on shared flights were separate from the passengers who were on the ship at the time the outbreak was detected. So they had actually left the ship before the outbreak was detected,” Jackson said.
“All the passengers that were on the ship after that detection phase were transported just several days ago on a private plane directly from the Canary Islands to here in Omaha, Nebraska,” he added.
CDC officials are working with local and state public health officials to ensure anyone who may have been exposed outside of the cruise ship isolates at home and monitors themselves for symptoms.
The officials on the call declined to say how many people are being monitored for possible exposure or where they are located in the country, citing privacy concerns.
They also declined to talk about the two cruise ship passengers taken to Emory University Hospital’s Serious Communicable Diseases Unit in Georgia.
Dr. David Fitter, incident manager for the agency’s hantavirus response, said that unlike the coronavirus pandemic that spread around the world in 2020, hantavirus is not new to public health officials.
“At this moment I want to emphasize that the risk to the general public is low,” he said.
In addition to monitoring Americans who were on the cruise ship and anyone they may have come into contact with, CDC officials have been talking frequently with lawmakers.
“We’ve held two Hill briefings and have just completed a call with the governors from the states of repatriated Americans,” Fitter said. “We’ve also held daily calls with state health officials.
“Our role now is to continue our conversations with each passenger about their potential exposure and work with partners to ensure appropriate monitoring.”
CDC officials have encouraged the people at the Nebraska facility to stay there throughout the quarantine period but there are not currently any state or federal quarantine orders in place.
