The Number That Changed

As of the CDC's May 14, 2026 press briefing, 41 people across the United States are under 42-day monitoring for Andes virus exposure. That's a significant jump from earlier in the week.

CDC Incident Manager Dr. David Fitter confirmed the number directly in Wednesday's briefing. Those 41 fall into three categories: passengers repatriated to the Nebraska Biocontainment Unit and Emory University Hospital in Atlanta, passengers who left the ship before the outbreak was identified, and people exposed on a commercial airplane.

The Airplane Exposure

According to the New York Times, 16 additional Americans are being monitored because they sat on a flight to Johannesburg with an infected Dutch woman who later died. The exposure had nothing to do with the cruise ship itself.

Hantavirus — specifically the Andes strain — is the only known hantavirus that spreads person-to-person. Most strains only jump from rodents to humans. The Andes strain has a documented history of human-to-human transmission, though rare. The airplane exposure cluster resulted from contact with an infected patient in an enclosed cabin, not from environmental contamination.

Most mainstream coverage has focused on the total number of 41 people without emphasizing the airplane exposure angle. The Washington Post headline highlighted the total figure without making the aircraft transmission the centerpiece. The detail shifts the risk calculus for regular travelers.

What Officials Are Saying

Dr. Fitter told the briefing Wednesday: "The risk to the general public is low."

The CDC's May 12 situation report supports this — zero confirmed Andes virus cases in the United States as a result of this outbreak.

The New York Times science reporting notes that officials may be downplaying risks. Their reporting cites documented cases where the Andes virus spread between people without direct physical contact. The scientific record supports this concern.

The CDC is technically accurate on case numbers. The framing of "extremely low" risk warrants scrutiny: 41 monitored Americans, an airplane exposure cluster, and a 42-day incubation window still in progress.

Where the 41 People Are

According to TODAY and CDC sources:

• 16 passengers are at the National Quarantine Unit at the University of Nebraska Medical Center in Omaha
• 2 people are at Emory University Hospital in Atlanta — one a former cruise passenger who showed mild symptoms, one their partner
• The remaining individuals are being monitored in their home states

One person at the Nebraska facility tested positive earlier, then tested negative and was moved from the biocontainment unit to a standard quarantine room. No one in Omaha is currently showing symptoms or elevated temperatures, according to Dr. Michael Wadman, medical director of the National Quarantine Unit, speaking on TODAY Wednesday morning.

Neither the Emory patient nor their partner has tested positive for Andes virus. The mildly symptomatic Emory patient tested negative.

The 42-Day Clock and the Quarantine Question

The World Health Organization recommends 42 days of monitoring — the full length of the Andes virus incubation period. The CDC is encouraging passengers to stay in quarantine facilities for that full window, which began Monday.

Currently, there are no state or federal quarantine orders in place. Dr. Fitter confirmed this Wednesday: "Currently, there are no state or federal quarantine orders that have been drawn."

People being monitored at home — those who left the ship before anyone knew there was an outbreak — are operating on voluntary compliance. The CDC is "working closely" with them to communicate expectations. This differs fundamentally from a formal quarantine.

What the CDC Is Doing Right

The CDC activated its Emergency Operations Center. Staff were deployed both overseas and domestically. High-containment repatriation to Nebraska and Emory — two of the best biocontainment facilities in the country — was executed competently. Port health stations are running 24/7.

The agency has also provided regular press briefings with publicly posted transcripts.

What This Means for You

If you're a regular American who wasn't on the MV Hondius and wasn't on a flight to Johannesburg, your risk right now is low. The CDC's public risk assessment appears accurate.

But 41 monitored Americans, a 42-day clock still running, voluntary-only quarantine for home-based exposures, and an airplane transmission cluster warrant continued attention. Any increase in the number of monitored individuals could change the risk picture substantially.
