What is Hantavirus?

What is Hantavirus?

Hantavirus is a group of viruses that can infect humans and some animals, especially rodents. People usually become infected after breathing in particles from rodent urine, droppings, or saliva that have been stirred up into the air.

It is not a common infection in the UK, but it is taken seriously because some types of hantavirus can cause severe illness. The risk is generally higher in places where rodents live indoors or where cleaning disturbs contaminated dust.

How it spreads

Hantavirus does not usually spread from person to person. In most cases, infection happens when someone is exposed to virus particles in rodent waste or contaminated material.

This can happen while sweeping out sheds, garages, lofts, or barns, especially if the area has signs of rodent activity. Rodent bites can also spread infection, although this is less common.

Symptoms to watch for

Early symptoms often start like flu and may include fever, tiredness, muscle aches, headache, dizziness, and stomach upset. Some people may also notice nausea, vomiting, or diarrhoea.

With certain hantavirus infections, breathing problems can develop later and become serious quickly. If symptoms worsen or breathing becomes difficult, urgent medical help is needed.

Hantavirus in the UK

Cases of hantavirus are uncommon in the UK, but there have been infections linked to native rodents, particularly the bank vole. The illness seen in the UK is usually a milder form than the severe disease reported in some other parts of the world.

Even so, it is important to take precautions when cleaning areas where rodents may have been active. Public health advice focuses on reducing contact with rodent droppings and urine.

How to reduce your risk

Good hygiene and pest control are the best ways to lower the risk of infection. Seal gaps where rodents can enter, store food securely, and keep kitchens, sheds, and outbuildings clean.

If you need to clean a rodent-infested area, avoid sweeping or vacuuming dry droppings straight away. Instead, ventilate the space, wear gloves, and use disinfectant to dampen contaminated material before cleaning it up.

When to get medical advice

If you think you may have been exposed to rodents and then develop fever, muscle aches, or breathing problems, contact NHS 111 or your GP for advice. Tell them about the possible exposure so they can consider hantavirus.

Seek urgent help if you have trouble breathing, chest pain, or symptoms that are getting worse quickly. Early medical assessment can help reduce the risk of serious complications.

What is Hantavirus?

Hantavirus is a group of viruses. Viruses are tiny germs. They can make people and some animals ill, especially rats and mice.

People usually catch it by breathing in tiny bits from rodent urine, droppings, or saliva. These tiny bits can get into the air.

It is not common in the UK. But doctors take it seriously because some types can make people very ill. The risk is higher in places where rats or mice live indoors. It is also higher when cleaning makes dirty dust go into the air.

How it spreads

Hantavirus usually does not spread from one person to another.

Most people catch it from contact with rodent waste or dirty material that has the virus in it.

This can happen when cleaning sheds, garages, lofts, or barns. It is more likely if there are signs of rats or mice.

Rodent bites can also spread the infection. This is less common.

Symptoms to watch for

Early signs can feel like flu.

These may include:

• fever
• tiredness
• sore muscles
• headache
• dizziness
• upset stomach
• feeling sick
• being sick
• diarrhoea

Some types of hantavirus can later cause breathing problems. This can become serious very quickly.

If breathing gets hard, get urgent medical help.

Hantavirus in the UK

Hantavirus is uncommon in the UK.

There have been some cases linked to wild rodents, especially the bank vole.

Illness in the UK is often milder than in some other countries. Even so, care is still needed.

Take extra care when cleaning places where rats or mice may have been.

Public health advice says to avoid touching rodent droppings and urine.

How to reduce your risk

Good cleaning and pest control can help keep you safe.

You can reduce risk by:

• sealing holes and gaps so rodents cannot get in
• storing food in closed containers
• keeping kitchens, sheds, and outbuildings clean
• getting help to deal with rodent problems

If you need to clean an area where rodents have been, do not sweep or vacuum dry droppings first.

Open windows or doors to let fresh air in.

Wear gloves.

Use disinfectant to wet the droppings or dirty material before you clean it up.

Helpful tools may include rubber gloves, disinfectant, and a face covering if the area is very dusty.

It can also help to work slowly, take breaks, and ask someone else to help if the job feels too hard.

When to get medical advice

If you think you may have been near rodents and then feel unwell, contact NHS 111 or your GP.

Tell them about the possible contact with rodents.

Get help if you have:

• fever
• muscle aches
• breathing problems
• chest pain
• symptoms that get worse quickly

Go for urgent help if breathing becomes difficult or you feel much worse fast.

To help you explain your symptoms, you can write them down before you call.

You can also ask a trusted person to help you make the call or go with you.
