Hantavirus Symptoms in Older People and How to Stay Safe at Home

Most people in Lewisham and Southwark will never encounter hantavirus. Cases remain rare across the UK, and the overall risk to the public is very low.

Even so, understanding the signs of illness and knowing how to reduce exposure to rodents can help older people and their families feel more confident about staying safe at home.

Understanding hantavirus

Hantavirus is a virus linked to infected rodents, including mice and rats.

People can become unwell through contact with rodent droppings, urine, or saliva. In many cases, infection is believed to happen when contaminated dust particles are breathed in.

Potential exposure can occur when:

• Cleaning rodent-affected areas
• Entering enclosed spaces where rodents have been active
• Touching contaminated surfaces
• Handling rodent waste without protective equipment

Garages, lofts, sheds, basements, storage areas, and caravans can sometimes be affected.

Why older people may be more vulnerable

Recovering from infections can become more difficult with age.

For people already living with health conditions such as diabetes, heart disease, lung conditions, or reduced mobility, even mild illnesses can have a greater impact on everyday life.

Understanding symptoms and acting early can help families seek support when needed.

Symptoms to watch for

Early signs of hantavirus may include:

• Fever
• Headaches
• Muscle pain
• Fatigue
• Dizziness
• Nausea
• Chills

In some cases, symptoms may progress and include:

• Chest discomfort
• Shortness of breath
• Difficulty breathing

Medical advice should be sought if symptoms develop after possible rodent exposure.

Practical ways to reduce risk

Check for rodent activity

Look out for:

• Droppings
• Nesting materials
• Chewed packaging
• Scratching sounds

Addressing signs early can help prevent larger infestations.

Use safe cleaning methods

Never sweep or vacuum droppings directly.

Instead:

• Ventilate the area
• Wear gloves
• Apply disinfectant
• Use disposable cleaning materials
• Seal waste before disposal

Reduce attractions for rodents

Store food in sealed containers and dispose of rubbish regularly.

Take care with storage areas

Unused spaces often provide shelter for rodents. If a property has not been accessed for some time, take precautions before cleaning.

When to get medical help

Speak to NHS 111 or your GP if symptoms appear after possible exposure.

Call 999 if someone experiences severe breathing difficulties, chest pain, or a sudden deterioration in their condition.
