A Plain-English Guide to the 2026 Outbreak](https://hantacount.com/en/learn/what-is-hantavirus): A clear, evidence-based explanation of hantavirus: what it is, how it spreads, the diseases it causes, and what the May 2026 MV Hondius outbreak means for travelers and the public. - [Andes Virus: Why This Hantavirus Strain Is Different](https://hantacount.com/en/learn/andes-virus): The Andes virus (ANDV) is the only hantavirus with documented person-to-person transmission. A deep look at its reservoir, history, mortality, and why it is at the center of the 2026 MV Hondius outbreak. - [Hantavirus Symptoms: Early Signs, Timeline, and When to Seek Care](https://hantacount.com/en/learn/symptoms): Hantavirus symptoms appear 1 to 8 weeks after exposure and progress in two phases. Learn the early warning signs, the dangerous deterioration window, and when to call a clinician — especially after possible MV Hondius exposure. - [Hantavirus Treatment: What Doctors Do (and What Doesn't Exist Yet)](https://hantacount.com/en/learn/hantavirus-treatment): There is no approved antiviral drug for hantavirus. Survival depends on early ICU admission, aggressive supportive care, and — in the most severe cases — extracorporeal membrane oxygenation. Here is what the evidence actually says. - [Hantavirus Prevention: 10 Steps to Reduce Your Risk](https://hantacount.com/en/learn/hantavirus-prevention): Hantavirus has no vaccine and no cure, which makes prevention the only reliable strategy. These ten evidence-based steps cover rodent avoidance, safe cleaning, respiratory protection, camp hygiene, and travel precautions for Patagonia and beyond. - [How Is Hantavirus Diagnosed? PCR, ELISA and What to Tell Your Doctor](https://hantacount.com/en/learn/hantavirus-diagnosis): Hantavirus diagnosis requires specific laboratory tests — RT-PCR, ELISA IgM and IgG — that most hospitals do not run routinely. Learn which tests confirm infection, when they turn positive, what a false negative looks like, and exactly what to tell the emergency team. - [Hantavirus Incubation Period: What to Expect After Exposure](https://hantacount.com/en/learn/hantavirus-incubation-period): Hantavirus symptoms can take 2 to 8 weeks to appear after exposure.

This guide compares the two syndromes across geography, symptoms, diagnostics, and treatment so clinicians and exposed patients know which they are dealing with. - [Is Hantavirus the Next COVID? A Sober Comparison](https://hantacount.com/en/learn/hantavirus-vs-covid): Hantavirus is dangerous to those who get it but biologically very different from SARS-CoV-2.
