What is Hantavirus?

Hantaviruses are a family of viruses that are primarily spread by rodents, such as rats, mice, and voles. Although the animals themselves usually do not become ill, they can spread the virus through urine, droppings, and saliva. 

People are usually infected by inhaling virus particles that are present in dust. This can happen, forexample, when cleaning areas where rodents have been present. 

The virus occurs worldwide, including in parts of Europe, Asia, and North and South America. 

What makes the Andes variant unique?

The Andes virus (ANDV) is a specific variant of Hantavirus found in South America. This variant is exceptional because it is the only known hantavirus variant for which human-to-human transmission has been demonstrated. 

This transmission mainly occurs through close and prolonged contact in enclosed spaces, for example through coughing or saliva droplets. 

How does Hantavirus spread?

Infection usually occurs through: 

• Inhaling dust particles contaminated with rodent droppings 

• Direct contact with infected rodents 

• Contact with contaminated surfaces or food 

In rare cases, the Andes variant can also be transmitted from person to person. Coughing in enclosedspaces especially increases the risk of transmission. Under ideal conditions, the virus can survive on surfaces for some time, making indirect contact a possible route of infection as well. 

What are the symptoms of Hantavirus?

Symptoms vary depending on the type of hantavirus, but common symptoms include: 

Early stage 

• Sudden high fever 
• Severe muscle pain
• Headache
• Fatigue
• Nausea or abdominal pain 

Late stage
In severe infections, lung or kidney problems may develop, including: 

• Increasing cough 
• Severe shortness of breath 
• Fluid buildup in the lungs 
• Breathing difficulties 

The Andes virus can lead to what is known as Hantavirus Pulmonary Syndrome (HPS), a serious lungcondition. 

Is Hantavirus dangerous?

Yes. Severe infections with the Andes virus can be life-threatening. The mortality rate for severe Andes virus infections ranges between 30% and 60%. 

There is currently no specific treatment, antiviral medication, or vaccine for Hantavirus. Earlyrecognition and prompt medical care are therefore important. 

In which countries does Hantavirus occur?

Hantavirus infections occur in, among other places: 

• South America 
• The United States and Canada 
• Parts of Europe 
• Asia 

The risk varies by region and type of travel. Travelers staying in natural areas, remote accommodations, or regions with high rodent activity are at greater risk. 

How can you prevent infection?

You can reduce the risk of infection by: 

• Avoiding contact with rodents 
• Not leaving food uncovered 
• Keeping accommodations clean and well ventilated
• Washing hands regularly
• Being cautious when cleaning dusty spaces 
• Not using a dry broom to clean rodent droppings
