Can my cat give me hantavirus?
Is it airborne or only from bites?
How deadly is it, really?
People ask these questions every day. The answers exist in the peer-reviewed literature. Scattered across dozens of papers. Behind paywalls. Written for specialists.
We ran the full synthesis on BioSkepsis — 15 verified PMIDs, every claim grounded to source, unverified citations flagged transparently.
Here's what the evidence actually says:
➡️ Transmission is primarily airborne — inhaling dust from dried rodent urine/feces, not bites
➡️ Hantavirus Pulmonary Syndrome kills 35–50% of patients in the Americas
➡️ There is no vaccine. No antiviral. Survival depends on early intensive care
➡️ Cats are dead-end hosts — but they bring infected rodents into your house
➡️ The single most effective prevention: wet contaminated surfaces before cleaning. That's it.
No hedging. No hallucinated citations. No "consult your doctor" cop-out where a PMID would do.
