To avoid spreading norovirus at home, wash hands often with soap and water for at least 20 seconds, and do not rely on hand sanitizer alone. Keep the sick person away from food preparation and close contact where possible. Clean vomit or diarrhea promptly with gloves and a norovirus-effective disinfectant, wash contaminated laundry separately, and continue extra precautions for at least 48 hours after symptoms stop.
Norovirus spreads easily through tiny amounts of infected vomit or stool that reach another person's mouth, often through contaminated hands, food, or household surfaces. When someone vomits, droplets can also contaminate nearby areas. A consistent cleaning routine, careful handwashing, and temporary changes to household activities can help reduce transmission between family members. These steps are particularly important when several people share a bathroom, kitchen, or living space.
How does norovirus spread between family members?
According to the Centers for Disease Control and Prevention (CDC), norovirus can spread through contaminated food, water, objects, and surfaces. People may accidentally swallow microscopic particles from an infected person's vomit or stool after touching a contaminated surface or handling food. Vomiting can also release droplets that land on nearby surfaces or food.
Someone with norovirus is most contagious while experiencing symptoms, particularly vomiting, and during the first few days after feeling better. However, the virus can remain in stool for two weeks or longer after symptoms stop. This is why household hygiene remains important even when the sick person appears to have recovered.
Which handwashing habits help prevent norovirus?
Washing hands properly is one of the most important ways to reduce household transmission. The CDC's norovirus prevention guidance recommends washing with soap and water for at least 20 seconds. Alcohol-based hand sanitizers do not work well against norovirus and should not replace handwashing.
Wash your hands thoroughly at these times:
- After using the toilet or helping someone use it.
- After changing a diaper or cleaning vomit or diarrhea.
- After handling soiled clothing, towels, or bedding.
- Before preparing, serving, or eating food.
- Before giving medicine or caring for another person.
- After taking out contaminated waste or finishing household cleaning.
Use running water and soap, rub all surfaces of your hands, including between your fingers and around your nails, and rinse thoroughly. Dry your hands with a clean towel. If you are caring for someone who is ill, wash your hands after removing gloves as well. Gloves provide an extra barrier during cleanup, but they do not replace handwashing.
How should you clean a bathroom shared with someone who has norovirus?
Bathrooms can become contaminated when an infected person has diarrhea or vomits. If practical, have the sick person use a separate bathroom until they have recovered. When that is not possible, pay particular attention to shared fixtures and frequently touched surfaces.
Clean and disinfect the toilet seat, flush handle, taps, sink, bathroom door handle, and nearby surfaces regularly, especially after contamination. Use a disinfectant that is specifically effective against norovirus and follow its instructions for the surfaces being treated. Cleaning removes dirt and material from a surface, while disinfecting helps kill germs that remain.
The UK National Health Service (NHS) recommends careful handwashing, cleaning bathroom touchpoints, and avoiding close contact with other people while ill. Avoid sharing hand towels, face towels, and other personal items during the illness. Give the sick person their own clean towel and replace it when needed.
Keep toothbrushes and personal care items away from contaminated surfaces. Clean shared bathroom surfaces more frequently when the sick person has active vomiting or diarrhea, and wash your hands after cleaning.
How do you safely clean up vomit or diarrhea?
Clean contaminated areas as soon as it is practical to do so. Norovirus particles may spread to nearby objects during vomiting or diarrhea, so cleaning only the visible mess may leave contaminated surfaces behind. Keep other household members away from the affected area until cleanup and disinfection are complete.
- Put on disposable or rubber gloves. Use any additional protective equipment specified by the cleaning product's instructions.
- Remove the visible mess. Use paper towels or another disposable absorbent material. Avoid actions that could spread contaminated material to surrounding areas.
- Dispose of the waste carefully. Place used towels and other contaminated disposable materials in a plastic bag, secure it, and dispose of it according to local waste guidance.
- Clean and disinfect the entire affected area. Include nearby surfaces that may have been contaminated, not just the spot where the vomit or diarrhea landed.
- Allow the disinfectant to work. Keep the surface wet for the contact time stated on the product label. For the bleach solution described in its norovirus guidance, the CDC recommends at least five minutes.
- Finish by washing your hands. Remove gloves carefully, avoid touching your face during cleanup, and wash your hands thoroughly with soap and water.
The CDC recommends using an appropriate chlorine bleach solution or an EPA-registered disinfectant effective against norovirus for contaminated areas. Follow the product label for dilution, surface compatibility, ventilation, protective equipment, and contact time. Never mix bleach with other cleaners or disinfectants, as this can release dangerous fumes.
If a surface may be damaged by bleach, choose an alternative disinfectant whose label specifically identifies effectiveness against norovirus and confirms that it is suitable for that surface. Ordinary household cleaning products should not automatically be assumed to kill the virus.
How should you handle contaminated laundry and bedding?
Clothing, towels, and bedding soiled with vomit or stool can carry norovirus. Handle these items carefully to reduce the chance of contaminating your hands, clothing, or nearby surfaces.
- Wear disposable or rubber gloves when handling soiled laundry.
- Remove contaminated items carefully and avoid shaking them.
- Keep them separate from other laundry when practical.
- Wash them with detergent using the hottest appropriate water setting and the longest available cycle that is suitable for the fabric.
- Machine-dry the items at the highest heat setting appropriate for the fabric.
- Clean your hands thoroughly after handling laundry and disinfect any surfaces that became contaminated.
Follow the washing machine, detergent, and fabric care instructions. The UK government's norovirus prevention guidance also recommends washing contaminated clothing and bedding separately on a hot wash and using bleach-based cleaners to disinfect appropriate surfaces.
How can you prevent norovirus from spreading through food?
Food handling deserves special attention because an infected person can contaminate food through unwashed hands or contact with contaminated kitchen surfaces. Someone who is sick should not prepare or handle food for other people, even if the food will be served later.
To reduce the risk of household food contamination:
- Have another household member prepare meals while the sick person is recovering.
- Wash your hands with soap and water before cooking, serving, or eating.
- Clean and disinfect kitchen counters, cutting boards, utensils, and other food-contact surfaces when contamination is suspected.
- Wash fruits and vegetables before preparing or eating them.
- Discard food that may have been contaminated by vomit, stool, or an infected person's unwashed hands.
- Avoid sharing food directly from common serving dishes when contamination is a concern.
The sick person should wait at least 48 hours after symptoms stop before preparing food for others or providing care to others. This precaution is especially important in households with young children, older adults, or people whose immune systems are weakened.
How long should a household follow these precautions?
Continue to take extra care while the person is ill and for at least 48 hours after vomiting and diarrhea have stopped. During this period, they should remain home rather than attend work, school, or childcare, and should avoid visits to hospitals or care homes. These measures help reduce opportunities to transmit the virus to others.
Feeling better does not necessarily mean that the virus has completely left the body. Norovirus may continue to be present in stool for two weeks or longer after symptoms disappear. After the first 48 hours, resume normal activities as appropriate, but continue careful handwashing, bathroom hygiene, and safe food handling.
Household members who have not become ill should keep up these habits as well. Do not assume that a shared surface is safe simply because it looks clean, and do not stop washing hands carefully once the sick person feels better.
What if another family member starts developing symptoms?
If another person develops vomiting or diarrhea, apply the same precautions immediately. Use gloves for cleanup, disinfect affected surfaces, wash contaminated laundry carefully, and ensure that the newly ill person does not prepare food for others. If several household members become ill, keeping cleaning supplies and handwashing facilities accessible can help everyone follow these measures consistently.
Preventing transmission is important, but so is recognizing when someone may need medical help. Seek medical advice if an ill person cannot keep fluids down, has signs of dehydration, or has concerning symptoms such as bloody diarrhea. Babies, young children, older adults, and people with weakened immune systems may need particular attention if fluid loss occurs.
The most useful household routine is simple: wash hands with soap and water, keep food preparation separate from caregiving while someone is ill, disinfect contaminated surfaces promptly, and handle laundry carefully. Following these steps during illness and maintaining good hygiene afterward can reduce the chance of norovirus spreading from one family member to another.
