As winter tightens its icy grip on the UK, another seasonal menace continues to circulate, norovirus, more commonly known as the ‘winter vomiting bug’. This highly contagious virus is the leading cause of stomach bugs in the UK, resulting in unpleasant symptoms such as nausea, vomiting, diarrhoea, and stomach cramps. While most people recover within a few days, norovirus spreads with alarming ease, making prevention and effective cleaning essential in halting its relentless advance.
The Spread of Norovirus
Norovirus is a master of stealth, spreading rapidly in environments where people are in close contact. Schools, hospitals, care homes, cruise ships, and restaurants often bear the brunt of outbreaks, but any public space can become a breeding ground for this tenacious virus.
According to NHS England, norovirus levels in hospitals in England are 80% higher than during the same period last year, with an average of 898 patients hospitalised daily in the week ending 24th January 2025
Unlike bacterial infections, which can sometimes be treated with antibiotics, norovirus has no specific cure. Instead, it spreads through direct contact with an infected person, consuming contaminated food or water, or touching infected surfaces. Once introduced into a space, it lingers, capable of surviving on surfaces for days, waiting for an unsuspecting host to touch a contaminated handle, tabletop, or even a shared electronic device.
Preventing Norovirus
Since norovirus is so contagious, prevention is critical. Simple yet effective hygiene practices can significantly reduce the risk of infection.
Hand Hygiene: A Crucial Barrier
Handwashing is one of the most effective ways to help prevent several common illnesses including norovirus. However, not all methods are equal. Unlike some other germs, norovirus is resistant to alcohol-based hand sanitisers, meaning washing hands with soap and warm water for at least 20 seconds is the gold standard. This is particularly crucial after using the toilet, before eating, and after contact with someone unwell.
Surface Disinfection: Stamping Out the Virus
Norovirus can survive on surfaces for extended periods. Frequently touched surfaces such as door handles, light switches, handrails, and shared equipment must be regularly disinfected with bleach-based cleaners, as traditional household cleaners may not be effective against norovirus.
Proper Food Handling: A Hidden Risk
Foodborne transmission is another significant concern. The virus can spread through contaminated food, particularly raw fruits and vegetables, shellfish, and ready-to-eat meals that infected individuals have handled. Thorough washing of produce, safe food preparation, and proper storage can help prevent foodborne outbreaks.
Managing Laundry: Hidden Contamination
Norovirus particles can cling to fabrics, so clothing, bed linens, and towels used by infected individuals should be washed promptly. Fabric-covered objects such as curtains, dividers, and chairs should also be considered. To kill the virus effectively, use a high-temperature wash (at least 60°C) with detergent. Avoid shaking contaminated fabrics, as this can release viral particles into the air and spread the infection further.
Staying Home: Breaking the Chain of Infection
Anyone experiencing symptoms should stay home for at least 48 hours after their symptoms have subsided. This is crucial in preventing further spread, especially in workplaces, schools, nursing and healthcare settings where outbreaks can escalate rapidly.
Specialist Cleaning: A Shield Against Norovirus Outbreaks
Standard cleaning practices may not be enough for businesses and facilities dealing with large groups of people. This is where professional disinfection services play a vital role. At Rentokil Specialist Hygiene, we provide expert infection control solutions designed to eliminate norovirus effectively from contaminated environments.
Our highly trained technicians utilise state-of-the-art methods such as Ultra Low Volume (ULV) disinfection fogging, which disperses tiny disinfectant droplets that reach even the most hard-to-access areas. This method ensures that both surfaces and the air are treated, significantly reducing the number of viable infectious pathogens. Our team is fully equipped with specialist protective gear, including Personal Protective Equipment (PPE) and Respiratory Protective Equipment (RPE), ensuring a thorough and safe cleaning process.
Responding to an Outbreak
If an outbreak occurs, quick and effective intervention is crucial. Here are the essential steps for containing and eliminating norovirus from a facility:
- Isolate All Affected Individuals – Minimise contact between symptomatic individuals and others to limit the spread.
- Implement Enhanced Cleaning Protocols – Increase the frequency and intensity of cleaning, focusing on high-contact areas.
- Use Specialist Cleaning Services – Professional disinfection ensures a deep and comprehensive cleanse, removing viral particles effectively.
- Monitor for Recurrence – Continue heightened hygiene practices even after symptoms have subsided to help prevent reinfection.
How Long Does Norovirus Last on Surfaces?
One key reason outbreaks can persist is the ability of the norovirus to survive on surfaces. Research suggests that if not properly disinfected, norovirus can remain infectious on hard surfaces for up to two weeks. Subsequently, even if an infected individual has recovered, their surroundings may still harbour the virus, posing a risk of reinfection to others.
How to Disinfect Your Home After Norovirus
If someone in your household has had norovirus, taking immediate steps to disinfect your home is essential.
- Clean all hard surfaces: Use a bleach-based disinfectant to wipe down bathroom fixtures, kitchen counters, doorknobs, and other high-touch surfaces.
- Wash all bedding and towels: Use the highest temperature setting on your washing machine.
- Ventilate the space: Open windows to allow fresh air to circulate and help clear airborne particles.
- Dispose of contaminated waste: Before disposal, seal in a bag any tissues, wipes, or cleaning cloths used during the clean-up.
The Bottom Line: Staying One Step Ahead of Norovirus
Norovirus may be a formidable foe, but its spread can be significantly minimised with vigilance, hygiene, and expert cleaning solutions. Whether you’re an individual looking to protect your home or a business aiming to safeguard employees and customers, taking proactive measures is the key to staying one step ahead of this relentless virus.
