Andes Hantavirus is Airborne:

There is a huge amount of downplaying and gaslighting this virus. Yes, it's serious if you get it and what stops spread is more its lethality than its ability to be shared. It is not only spread by touching infected mice, their droppings, urine, or some-such. It's also spread by being near someone who has it already.

Experts like Dr. Emily Abdoler (University of Michigan Health) have noted on news outlets that the Andes strain unique because it can travel via respiratory droplets when an infected person coughs or talks.

The official CDC Emergency Andes Virus Investigation Brief proves that hospitals are explicitly ordered to treat this as an airborne pathogen. The CDC officially instructs healthcare providers to place suspected Andes virus patients into an Airborne Infection Isolation Room (AIIR) and mandates that workers wear an N95 or higher-level respirator before entering the room to avoid breathing it

The scientific analysis published in The British Medical Journal (BMJ) features public health experts explicitly warning against downplaying the airborne risks of the Andes hantavirus. The authors demand that international agencies immediately implement strict precautionary airborne mitigation strategies—such as portable HEPA filtration and strict respirator use—across all tight quarantine quarters

The European Centre for Disease Prevention and Control (ECDC) Outbreak Report verifies that the primary way hantaviruses enter human populations is completely airborne. They note that the virus is contracted through the inhalation of aerosols contaminated with the urine, feces, or saliva of infected rodents that have become suspended in the ambient air.

​

Assumptions for this scenario:

- Andes virus mutates or is confirmed to spread via casual airborne contact (COVID-level R0 of ~2.5-3+)

- CFR remains in the 30-40% range without ECMO; ~15-20% with it

- No existing vaccine, no specific antiviral treatment

## Week 1-3: Detection Lag & Denial Window

This is the most dangerous phase. Because Andes hantavirus symptoms (fever, muscle aches, fatigue) are indistinguishable from flu for the first 4-7 days, and because the current framing is "contained cruise ship outbreak," widespread community transmission would likely go undetected for **2-3 weeks minimum**.

The US specifically has a problem here: the CDC has undergone significant budget cuts and restructuring under the current administration. The pandemic early warning infrastructure — particularly PREDICT and related programs — were already gutted after COVID. Surveillance capacity is genuinely degraded compared to 2020.

Internationally, WHO's capacity is also hampered. The US formally re-withdrew from WHO under Trump's second term, which fractures the coordination layer that actually matters in the first 30 days.

**Realistic outcome:** Silent spread in South America (Argentina, Chile especially, since that's the endemic rodent zone), Europe from the Hondius passengers, and potentially early US seeding through travel — all before any coordinated alarm is raised.

## Week 3-6: Alarm Without Coordination

Hospitals in multiple countries start seeing unexplained severe pneumonia clusters. The pattern gets recognized. This is where it diverges hard from COVID based on the current political environment.

**US-specific:**

- RFK Jr. is HHS Secretary. His instinct on novel pathogen response is deeply skeptical of institutional public health framing. Expect significant internal friction before any federal mobilization.

- The current administration's ideological posture is strongly against mask mandates, lockdowns, or anything that reads as "COVID 2.0" — politically toxic. That messaging will delay federal action by **weeks**, not days.

- ECMO capacity in the US is approximately 200-300 centers with maybe 2,000-3,000 machines nationwide. At a 30-40% CFR with COVID-level spread, those fill within **days** of a true surge. ECMO is not scalable like ventilators.

- No federal stockpile protocol exists for hantavirus PPE escalation.

**Europe:**

Faster and more coordinated response than the US, but post-COVID political fatigue is real. Germany, France, Netherlands have functional public health infrastructure. Expect European nations to move toward containment measures 2-3 weeks ahead of the US.

**Global South:**

Argentina and Chile are ground zero if this is circulating in rodent populations across the continent. Their healthcare systems — particularly ECMO capacity — are extremely limited. Sub-Saharan Africa, South Asia: essentially no ECMO infrastructure. This becomes a mass casualty event in those regions almost immediately upon spread.

## Month 2-3: The Pivotal Window

This is where the 30-40% CFR changes everything compared to COVID. COVID's ~1% IFR allowed governments to delay, hedge, and half-measure their way through. **A 30% CFR cannot be politically managed the same way.** Bodies are visible fast.

At COVID-level spread with this CFR, projecting even conservatively:

- US with COVID's first wave pace (~30M infected in 6 months): **9-12 million deaths** in that window without effective intervention. That's not a scenario any administration can spin.

This is where the Trump administration dynamic gets complicated and somewhat unpredictable:

- The initial instinct will be to downplay (economic, political reasons)

- But the death toll visibility at 30% CFR makes denial untenable faster than COVID — probably by **week 6-8** of recognized community spread

- Expect an abrupt pivot to aggressive nationalism: border closures, domestic production orders (DPA invoked), and a blame-China or blame-WHO framing regardless of the actual origin

**What won't happen quickly:**

- Coordinated international response (US-WHO estrangement is real)

- A national mask mandate (politically impossible in this administration)

- School/business closures at federal level — this will be pushed entirely to states, creating a red/blue divergence in outcomes that is statistically measurable and brutal

## Month 3-6: Vaccine Race Under Different Constraints

Here's a key difference from COVID: **mRNA platform exists and proved itself**. Moderna and BioNTech could theoretically develop an Andes virus mRNA vaccine candidate in 60-90 days of intensive work. The platform is there.

But:

- RFK Jr.'s FDA is more skeptical of accelerated approval pathways

- The EUA framework that allowed COVID vaccine emergency authorization could face internal political resistance

- Anti-vax sentiment in the US is now significantly higher than 2020 — even if a vaccine arrives fast, uptake would be materially lower

Realistically, a functional vaccine at scale is **12-18 months out** — similar to COVID — but with worse uptake and more political friction around mandates.

**Globally:** COVAX and similar equity mechanisms are weaker now. Expect a repeat of the vaccine nationalism from 2020-2021, likely worse because the US is less engaged with multilateral frameworks.

## The Honest Macro Picture

If this goes COVID-level transmissible, the honest answer is: **this would be the worst infectious disease event in recorded human history**, likely surpassing the 1918 flu in absolute death toll given global population size. The 1918 flu had roughly a 2-3% CFR and killed 50-100 million. A 30% CFR pathogen at COVID spread is a civilization-level event.

The saving grace — and it's the reason this scenario probably doesn't materialize — is that viruses with very high CFR tend to burn through their hosts too fast and face strong evolutionary pressure to attenuate. Andes becoming both highly transmissible AND maintaining 30-40% lethality would be somewhat unusual virology. High CFR and high transmissibility are generally in tension.

UPDATE: a contact case has been transferred from hospital isolation to Paris today, and they are expecting two other contact cases to be transferred to the specialized parisian hospital.

A young woman has been taken to hospital urgently and some french media is reporting suspected hantavirus. She was a passenger on the Johannesburg-Amsterdam flight and would therefore have caught it on the plane....However, I'm finding it difficult to tell whether this is reliable or not.

Are these videos and the photo of Spanish cruise passengers and their behavior (no masks/masks removed) real? They’re supposed to be in quarantine right now, so these recordings are fake?

People can spread the virus before they start showing symptoms, and it can take up to two to eight weeks for symptoms to appear. This can make it challenging to control the outbreak.
