Where is Hantavirus found?

What is hantavirus?

Hantaviruses are a group of viruses carried mainly by rodents. People can become infected if they breathe in dust contaminated with rodent urine, droppings, or saliva.

In humans, hantavirus can cause serious illness. The exact type of disease depends on the strain, but it may affect the lungs or kidneys.

Where is hantavirus found globally?

Hantavirus is found in many parts of the world, especially where wild rodents live close to people. Different strains are linked to different rodent species.

Cases have been reported in the Americas, Europe, Asia, and parts of Africa. The risk is often highest in rural areas, forests, farms, and places where rodent infestations are more likely.

Is hantavirus found in the UK?

Hantavirus is not considered a common infection in the UK. However, related hantaviruses have been detected in British rodents, and a small number of human cases have been reported over the years.

The risk to the general public in the UK is low, but it is not zero. People who work with rodents, clean heavily infested buildings, or spend time in rural settings may have a higher chance of exposure.

Which animals carry hantavirus?

Rodents are the main carriers of hantavirus. This includes mice, rats, voles, and some other small mammals, depending on the virus strain.

In the UK, wild rodents are the main concern rather than pets. The virus is usually spread when infected animals shed the virus in urine, droppings, or saliva.

Where are people most likely to come into contact with it?

People are most likely to be exposed in enclosed spaces where rodents have been living. This can include sheds, garages, barns, lofts, basements, and storage areas.

Outdoor activities can also pose a risk if they involve disturbing rodent nests or droppings. Sweeping, vacuuming, or handling contaminated materials can increase the chance of breathing in infectious particles.

How can the risk be reduced?

The best way to reduce risk is to avoid contact with rodent droppings and nesting materials. If cleaning a space with signs of rodents, open windows, wear gloves, and dampen the area before cleaning to reduce dust.

Good hygiene and pest control are also important. Sealing food, blocking entry points, and dealing with infestations quickly can help prevent rodents from spreading hantavirus.

When to seek medical advice

If you think you may have been exposed and then develop symptoms, speak to a GP or healthcare professional. Early symptoms can include fever, muscle aches, headache, and tiredness.

Although hantavirus is rare in the UK, prompt medical advice is important if you feel unwell after possible rodent exposure. This is especially true if you develop breathing difficulties or symptoms that worsen quickly.
