The outbreak on the MV Hondius is bad. It’s also confusing. We don’t fully understand how this thing moves through the air.
Eleven people sick. Three dead. All linked to the Andes strain of hantavirus. It is the only known version of the bug that jumps between humans. That distinction matters. A lot. As authorities watch passengers for the 42-day incubation period, we are left guessing at the mechanics of transmission.
How it usually works
Typically? Rodents. You get infected by breathing in dried pee or poop particles from mice or rats. It enters via the nose. In that specific sense yes, the air carries the virus from animal to human. Linsey Marr, a virulence spread expert at Virginia Tech, notes this is “well established.”
The question is whether an infected person releases virus into the air.
We don’t have a clean answer. The World Health Organization and CDC talk about “close” and “prolonged” contact. Vague words for vague science. Does “close” mean sharing a bed? A spoon? Or just sitting near someone who coughs?
If the virus hangs around in saliva or deep lung mucus, the risk profile changes. Does it survive there? For how long? “I don’t think we have any information,” says Marr. A sobering admission.
The birthday party clue
Past outbreaks offer hints. In Argentina (2018-2019), a man with rodent-derived fever crashed a party of 100 people. He sat there for 90 minutes. Later five of his neighbors got sick. One of them, while still incubating the disease, likely infected six others. He died. His spouse, still feverish, went to his wake. Ten more people at the funeral fell ill.
Aerosolized droplets seem the likely culprit. Or virions. It looks like inhalation did the heavy lifting.
So is the Andes virus highly transmissible like SARS-CoV-2? No. It isn’t that aggressive. But the party scenario suggests it spreads more easily than “close contact” implies. And that distinction could be the difference between a contained outbreak and a wider crisis as cruise passengers return home.
The Nebraska bunker
In the U.S., 16 people sit in the National Quarantine Unit in Omaha, Nebraska. Another two are in Atlanta.
This facility is intense. Rooms have negative pressure and HEPA filtration. It feels less like a jail cell and more like a luxury hotel with extra security. TVs? Check. Gym? Check.
Joshua Santarpia runs pathology there. He says they are using full airborne precautions—N95 masks, gowns, eye gear. They aren’t sure yet when they can drop those shields. Santarpia has studied Sin Nombre, another hantavirus that spreads only from rats, not people.
He admits the Andes situation is rare. “Extremely close or continuing contact” seems to be the trigger. An aerosol role? Plausible. But it won’t mimic the pandemic chaos of COVID-19. Probably.
Probably is a risky word when you’re holding your breath.
