CDC Issues Quarantine for Cruise Ship Passengers Over Hantavirus Concerns

In Omaha, Nebraska, U.S. health authorities have issued quarantine orders for two passengers from a cruise ship linked to a hantavirus outbreak. These passengers are currently hospitalized in Nebraska. The Centers for Disease Control and Prevention’s (CDC) acting director, Dr. Jay Bhattacharya, approved the orders, as stated in a CDC press release.

Quarantine orders are rarely enforced by law, entailing potential fines and imprisonment if not adhered to. All 18 passengers receiving care in the Nebraska hospital have been asked to remain until May 31, which is the end of their monitoring period, as per CDC guidelines.

During a briefing with reporters, CDC’s Dr. David Fitter confirmed no hantavirus cases among returned U.S. passengers so far. Jodie Guest, the senior vice chair of epidemiology at Emory University’s Rollins School of Public Health, noted symptoms of hantavirus could emerge up to 42 days post-exposure. She explained, “The 42-day waiting period can be lengthy for those under quarantine, but it aligns with the known incubation period.”

The CDC’s statement revealed three additional cases of hantavirus in passengers after the cruise, located in France, Spain, and Canada. The World Health Organization previously reported 11 cases linked to the cruise, leading to three fatalities. Eight of these cases have been lab-confirmed.

Hantaviruses typically spread through inhalation of infected rodent droppings. However, the current outbreak’s Andes virus strain might rarely spread between humans. Public health officials maintain the risk to the general public from this cruise incident is low.
