Norovirus, also known as the winter vomiting bug, is a highly contagious virus that can cause severe vomiting and diarrhea. It's a common cause of gastroenteritis, an inflammation of the stomach and intestines. Norovirus can affect people of all ages, but it's most common in children under the age of 5.
Norovirus is spread through contact with contaminated food, water, or surfaces. It can also be spread through close contact with an infected person, such as sharing food or drinks or touching the same surfaces. Symptoms of norovirus typically appear within 12 to 48 hours after exposure to the virus. The most common symptoms are vomiting, diarrhea, and stomach cramps. Other symptoms may include nausea, headache, low-grade fever, and body aches.
The duration of norovirus symptoms can vary from person to person. In general, symptoms last for 1 to 3 days. However, some people may experience symptoms for a longer period of time, especially if they have a weakened immune system. Additionally, norovirus can cause dehydration, so it's important to drink plenty of fluids to stay hydrated.
How Long Does Norovirus Last?
Norovirus is a highly contagious virus that causes vomiting and diarrhea. Symptoms typically last 1-3 days.
- Common in children under 5
- Spread through contact with contaminated food, water, or surfaces
- Symptoms appear 12-48 hours after exposure
- Vomiting, diarrhea, and stomach cramps are common symptoms
- Symptoms can last longer in people with weakened immune systems
- Dehydration is a risk, so drink plenty of fluids

Norovirus is a common cause of gastroenteritis, and it can be very unpleasant. However, it is usually not a serious illness, and most people recover within a few days. If you have symptoms of norovirus, it is important to stay home from work or school to avoid spreading the virus to others. You should also drink plenty of fluids to stay hydrated.
Common in Children Under 5
Norovirus is a very common cause of gastroenteritis in children under the age of 5. In fact, it is estimated that up to 50% of all cases of gastroenteritis in this age group are caused by norovirus.
- Immature immune systems: Children under 5 have immature immune systems, which makes them more susceptible to infection with norovirus.
Frequent exposure: Children in this age group are also more likely to be exposed to norovirus because they are often in close contact with other children, both at home and in childcare settings. They may also be more likely to put their hands or objects in their mouths, which can increase their risk of exposure to the virus. Less effective hygiene practices: Young children may not yet have fully developed hygiene practices, such as handwashing and covering their mouths when they cough or sneeze. This can make it easier for them to spread norovirus to others. Smaller body size: Children under 5 have smaller bodies, which means that they can become dehydrated more quickly than adults. Dehydration can worsen the symptoms of norovirus and lead to more serious complications.
Because of these factors, norovirus can be more severe in children under 5 than in older children and adults. It is important to be aware of the symptoms of norovirus and to seek medical attention if your child is experiencing them.
Spread Through Contact with Contaminated Food, Water, or Surfaces
Norovirus is a very contagious virus that can be spread through contact with contaminated food, water, or surfaces. This means that it can be spread in a variety of settings, including homes, schools, childcare centers, and restaurants.
- Eating or drinking contaminated food or water: Norovirus can contaminate food or water during preparation, handling, or storage. This can happen if an infected person handles food or water without washing their hands properly, or if food or water is contaminated with sewage or animal feces. Eating or drinking contaminated food or water can then spread the virus to others.
Touching contaminated surfaces and then touching your mouth: Norovirus can also be spread by touching surfaces that have been contaminated with the virus and then touching your mouth. This can happen in public places, such as doorknobs, countertops, and bathroom fixtures. It can also happen in homes, especially if someone in the household is infected with norovirus. Contact with an infected person: Norovirus can also be spread through close contact with an infected person, such as sharing food or drinks, or touching the same surfaces. This is why it is important to stay home from work or school if you are experiencing symptoms of norovirus. Vomiting or diarrhea: Norovirus can be spread through vomiting or diarrhea. When an infected person vomits or has diarrhea, the virus can be released into the air or onto surfaces. This can then spread the virus to others who come into contact with the contaminated air or surfaces.
Because norovirus is so contagious, it is important to take steps to prevent infection. These steps include washing your hands frequently with soap and water, avoiding contact with people who are sick, and cleaning and disinfecting surfaces that may be contaminated with the virus.
Symptoms Appear 12-48 Hours After Exposure
After you are exposed to norovirus, it typically takes 12 to 48 hours for symptoms to appear. This is known as the incubation period. During the incubation period, the virus is multiplying in your body, but you may not feel any symptoms.
Once the incubation period is over, you may start to experience symptoms of norovirus. The most common symptoms are vomiting, diarrhea, and stomach cramps. Other symptoms may include nausea, headache, low-grade fever, and body aches.
Symptoms of norovirus can be very unpleasant, but they usually only last for 1 to 3 days. However, some people may experience symptoms for a longer period of time, especially if they have a weakened immune system.
If you are experiencing symptoms of norovirus, it is important to stay home from work or school to avoid spreading the virus to others. You should also drink plenty of fluids to stay hydrated. Most cases of norovirus are mild and do not require medical treatment. However, if you have severe symptoms, such as dehydration or bloody diarrhea, you should seek medical attention.
Norovirus is a very contagious virus, so it is important to take steps to prevent infection. These steps include washing your hands frequently with soap and water, avoiding contact with people who are sick, and cleaning and disinfecting surfaces that may be contaminated with the virus.
Vomiting, Diarrhea, and Stomach Cramps Are Common Symptoms
The most common symptoms of norovirus are vomiting, diarrhea, and stomach cramps. These symptoms can be very unpleasant and can make it difficult to carry out your normal activities.
Vomiting: Norovirus can cause sudden and forceful vomiting. This can be very distressing and can lead to dehydration. It is important to drink plenty of fluids to stay hydrated. If you are vomiting frequently, you may need to see a doctor for intravenous fluids.
Diarrhea: Norovirus can also cause severe diarrhea. This can lead to dehydration and electrolyte imbalance. It is important to drink plenty of fluids and eat foods that are high in electrolytes, such as bananas, rice, and potatoes.
Stomach cramps: Norovirus can also cause stomach cramps. These cramps can be very painful and can make it difficult to eat or sleep. There are a number of over-the-counter medications that can help to relieve stomach cramps.
In addition to these common symptoms, norovirus can also cause other symptoms, such as nausea, headache, low-grade fever, and body aches. Symptoms of norovirus typically last for 1 to 3 days, but some people may experience symptoms for a longer period of time.

Most cases of norovirus are mild and do not require medical treatment. However, if you have severe symptoms, such as dehydration or bloody diarrhea, you should seek medical attention.
Symptoms Can Last Longer in People With Weakened Immune Systems
People with weakened immune systems are more likely to experience more severe and prolonged symptoms of norovirus. This is because their immune systems are less able to fight off the virus.
People with weakened immune systems include those who:
- Are very young or very old
- Have chronic health conditions, such as cancer, HIV/AIDS, or diabetes
- Are taking medications that suppress the immune system, such as chemotherapy or steroids
In people with weakened immune systems, symptoms of norovirus can last for more than a week. They may also be more likely to experience complications, such as dehydration, electrolyte imbalance, and malnutrition.
If you have a weakened immune system and you are experiencing symptoms of norovirus, it is important to see a doctor right away. You may need to be hospitalized for intravenous fluids and other supportive care.
There are a number of things that people with weakened immune systems can do to reduce their risk of norovirus infection. These include:
- Washing their hands frequently with soap and water
- Avoiding contact with people who are sick
- Cleaning and disinfecting surfaces that may be contaminated with the virus
- Getting vaccinated against norovirus (if available)
If you have a weakened immune system and you are concerned about norovirus, talk to your doctor.
Dehydration Is a Risk, So Drink Plenty of Fluids
Norovirus can cause severe vomiting and diarrhea, which can lead to dehydration. Dehydration occurs when you lose more fluids than you take in. This can be a serious problem, especially for young children and people with weakened immune systems.
Symptoms of dehydration include:
- Dry mouth and throat
- Decreased urination
- Dark yellow urine
- Headache
- Fatigue
- Dizziness
- Confusion
If you are experiencing symptoms of dehydration, it is important to drink plenty of fluids right away. The best fluids to drink are water, oral rehydration solutions, and electrolyte-rich drinks. Avoid sugary drinks, as these can worsen diarrhea.
If you are unable to drink fluids or if your symptoms are severe, you may need to be hospitalized for intravenous fluids. Intravenous fluids can help to rehydrate your body and restore your electrolyte balance.
To prevent dehydration, it is important to drink plenty of fluids throughout the day, even if you are not feeling sick. You should also drink more fluids if you are exercising or sweating heavily. If you are experiencing symptoms of norovirus, it is especially important to drink plenty of fluids to stay hydrated.
