Rapid orientation

The facts people are searching for right now.

Search interest is currently driven by the MV Hondius cluster, contagiousness questions, symptoms after exposure, and how to clean rodent-contaminated spaces safely.

What it is

Andes virus is a South American hantavirus associated with hantavirus cardiopulmonary syndrome, a rare but severe respiratory and cardiac illness.

How exposure happens

Most hantavirus infections follow contact with infected rodents or contaminated urine, droppings, saliva, nesting material, or dust.

Why Andes virus is different

Unlike most hantaviruses, Andes virus has documented limited person-to-person spread among close and prolonged contacts.

What lowers risk

Ventilate closed spaces, avoid dry sweeping rodent material, use wet disinfection methods, seal rodent entry points, and seek care early after compatible symptoms.

Current Outbreak Timeline

Key developments in the May 2026 cruise-linked cluster investigation.

First illness onset in WHO cluster

WHO reported the first known illness in the cruise-linked cluster began with fever, headache, and gastrointestinal symptoms.

Cruise-linked cluster escalates

A Dutch-flagged expedition vessel with passengers and crew from 23 nationalities became the focus of international investigation.

WHO source snapshot reaches 11 cases

WHO materials referenced 11 cases, including three deaths, while response teams continued contact tracing, monitoring, and risk assessment.

WHO publishes rapid risk assessment v2

WHO released a global rapid risk assessment for the MV Hondius-associated Andes virus event.

ECDC maintains very low general-population risk

ECDC continued publishing outbreak resources and reported that broader EU/EEA public risk remains very low.

Transmission risk

The primary route is environmental exposure to infected rodents. Andes virus deserves special attention because close-contact human transmission has been documented, but WHO still describes this as limited and uncommon.

  • Rodent urine, droppings, saliva, nests, or contaminated dust remain the core risk.
  • Household, intimate, or prolonged close contact can matter for Andes virus.
  • Severe respiratory symptoms after exposure require urgent medical evaluation.

Symptoms to take seriously

Hantavirus illness can begin like a nonspecific viral illness and then progress quickly. Clinical testing decisions belong with qualified healthcare professionals.

  • Fever, headache, and muscle aches after potential rodent or close-contact exposure
  • Gastrointestinal symptoms such as abdominal pain, nausea, vomiting, or diarrhea
  • Shortness of breath, pneumonia, acute respiratory distress, shock, or rapid deterioration
  • Symptoms can begin one to eight weeks after exposure depending on the virus and situation

Prevention is practical: reduce rodent exposure, clean safely, and act early.

This site is informational and not a substitute for medical care. If symptoms are severe or follow known exposure, contact emergency services or a qualified clinician.

  • Avoid entering or sleeping in rodent-infested areas until they are cleaned safely.
  • Ventilate enclosed spaces before cleanup and avoid sweeping or vacuuming dry rodent droppings.
  • Use gloves and disinfectant-wet cleanup methods for droppings, nests, and contaminated surfaces.
  • Store food securely, remove attractants, and seal holes that allow rodents into buildings.
  • Seek urgent medical advice if compatible symptoms follow rodent exposure or close contact with a suspected Andes virus case.

Reader questions

Common questions answered carefully.

Built for organic search without drifting into diagnosis, treatment promises, or panic marketing.

Is Andes virus contagious between people?

Most hantaviruses are not spread person-to-person. Andes virus is the key exception: limited transmission has been documented among close and prolonged contacts, including household or intimate contacts.

Is there a cure or vaccine?

WHO states there is no specific treatment that cures hantavirus disease. Early supportive medical care and close monitoring can improve survival.

Should travelers cancel South America trips?

A website cannot make individual medical or travel decisions. Travelers should follow official public-health guidance, avoid rodent exposure, and seek clinician advice for specific risk.
