Can Hantavirus be prevented?

Yes, hantavirus can often be prevented by reducing contact with infected rodents and their droppings, urine, and saliva. In the UK, the main risk comes from environments where mice or rats are living or nesting, such as sheds, garages, lofts, outbuildings, and poorly cleaned enclosed spaces.

There is no routine vaccine for hantavirus in the UK, so prevention depends on careful hygiene and sensible rodent control. The good news is that simple measures can greatly lower the risk.

Keep rodents out of your home

Blocking access is one of the most effective ways to prevent infection. Seal gaps around pipes, vents, doors, and walls, especially where mice could squeeze through.

Store food in sealed containers and clean up crumbs or spills quickly. Try to remove clutter in sheds, lofts, and cupboards, as these areas can provide hiding places for rodents.

Use safe cleaning methods

Never sweep or vacuum rodent droppings straight away, as this can stir contaminated dust into the air. Instead, open windows if possible, wear gloves, and spray the area with disinfectant or a bleach solution before cleaning.

Wipe up droppings and nesting material with disposable paper towels, then place everything in a sealed bag. Wash your hands thoroughly afterwards, even if you wore gloves.

Be careful in high-risk areas

If you are cleaning a shed, garage, barn, or holiday lodge that has been closed for a while, take extra care. Rodents are more likely to leave droppings in spaces that are quiet, dark, and undisturbed.

In these settings, avoid activities that could disturb dust unless the area has been properly aired and cleaned. If there is a heavy infestation, consider using professional pest control.

Protect yourself outdoors

When camping, gardening, or working in rural areas, avoid sleeping or eating in places where rodents may have been active. Keep tents and food secure, and do not leave rubbish that could attract mice or rats.

If you need to clear woodpiles, sheds, or animal bedding, wear gloves and take care not to create dust clouds. Good outdoor hygiene can make a big difference.

Know when to seek medical advice

Hantavirus infections are uncommon in the UK, but symptoms should not be ignored after possible rodent exposure. Early signs can include fever, muscle aches, tiredness, headache, and stomach upset.

If you think you may have been exposed and develop symptoms, contact your GP or NHS 111 for advice. Quick assessment is important, especially if you feel short of breath or unwell.
