What Is Hantavirus? — Everything You Need to Know in 2026

Hantaviruses are a family of viruses spread mainly by rodents and can cause diverse disease syndromes in people worldwide. Infections with any hantavirus can produce hantavirus disease in people.

How Does Hantavirus Spread?

The virus is mainly transmitted to people when they breathe in air contaminated with the virus from rodent urine, droppings, or saliva. Person-to-person transmission is extremely rare, though it has been historically reported with the Andes virus in South America.

Hantavirus Symptoms

  • Early symptoms: Fatigue, fever, muscle aches (especially thighs, hips, back).
  • Late symptoms (HPS): Coughing, shortness of breath, fluid in lungs.
  • Late symptoms (HFRS): Low blood pressure, acute shock, vascular leakage, acute kidney failure.

Is Hantavirus Deadly? — Fatality Rate

  • Hantavirus Pulmonary Syndrome (HPS) has a mortality rate of about 38%.
  • Hemorrhagic Fever with Renal Syndrome (HFRS) has a mortality rate ranging from 1% to 15% depending on the specific virus strain.

Hantavirus Prevention

Rodent control is the primary strategy. Seal holes inside and outside homes, trap mice and rats, and clean up rodent food sources and nesting sites.

Hantavirus vs COVID-19

Unlike COVID-19, hantavirus is not primarily an airborne human-to-human respiratory virus. It requires direct contact with or inhalation of aerosolized rodent excreta. The outbreak potential is generally localized.

Frequently Asked Questions

Common questions about hantavirus and the 2026 outbreak.

QIs hantavirus airborne?

Hantavirus is transmitted through inhalation of aerosolized particles from infected rodent urine, droppings, or saliva — not through casual airborne contact between people. The virus becomes airborne when dried rodent excreta is disturbed, such as during cleaning. It is not spread through coughing or sneezing between humans.

QCan hantavirus spread from person to person?

Most hantavirus strains, including Sin Nombre virus (North America), do not spread between people. Andes virus is the documented exception: close contact with an infected person can result in transmission, as seen in the MV Hondius 2026 cluster. Standard infection-control precautions (masks, hand hygiene, isolation) are recommended for confirmed cases.

QWhere is hantavirus most common?

Hantavirus is found worldwide. In the Americas, Sin Nombre virus is prevalent across the western United States, while Andes virus is endemic to Patagonia (Argentina and Chile). In Europe and Asia, Seoul and Puumala viruses circulate broadly. Cases are most common in rural areas with high rodent populations.

QWhat is the hantavirus fatality rate?

Hantavirus Pulmonary Syndrome (HPS), caused by strains like Sin Nombre and Andes virus, has a case-fatality rate of approximately 38%. Hemorrhagic Fever with Renal Syndrome (HFRS), caused by strains like Seoul and Hantaan virus, has a lower fatality rate of 1–15% depending on the specific strain.

QIs there a vaccine for hantavirus?

There is no FDA-approved vaccine for hantavirus in the United States or most Western countries. Some vaccines have been developed and used in China and South Korea for HFRS strains. Research into broader hantavirus vaccines is ongoing. Prevention currently relies on rodent control and avoiding exposure to rodent excreta.

QWhat happened on the MV Hondius cruise ship?

In late April 2026, a cluster of Andes virus (hantavirus) cases was identified among passengers and crew of the MV Hondius, a cruise ship operating in the South Atlantic near Patagonia. The outbreak is significant because Andes virus is the only hantavirus known to spread person-to-person. WHO has issued multiple Disease Outbreak News reports tracking the cluster.

QHow is hantavirus different from COVID-19?

Unlike COVID-19, hantavirus is not a human respiratory virus that spreads through the air between people. It requires direct contact with or inhalation of aerosolized rodent excreta. Hantavirus does not cause large-scale human-to-human transmission chains (with the rare exception of Andes virus), so its outbreak potential is generally localized rather than pandemic.

QShould I be worried about hantavirus in 2026?

For most people, the risk of hantavirus infection remains low. The MV Hondius cluster is a notable event due to Andes virus's rare person-to-person transmission, but it is geographically contained. The greatest risk is for people in rural areas with rodent exposure. Follow standard prevention: avoid contact with rodents, seal entry points in buildings, and use proper protective equipment when cleaning potentially contaminated areas.
