Norovirus, also known as Norwalk virus or the winter vomiting bug, is an extremely contagious virus that causes an acute gastroenteritis (vomiting and diarrhea) that can last from one to three days.
Although norovirus can cause serious illness in people with weak immune systems or other underlying health conditions, it usually goes away on its own and does not require treatment.
However, in some cases you might experience dehydration or need to be hospitalized for intravenous fluid replacement if your vomiting lasts more than 48 hours or you are unable to drink enough liquids to prevent dehydration.
What is norovirus?
Norovirus is a highly contagious virus that can cause you vomit and diarrhea. It is often called the stomach flu or food poisoning.
Norovirus is transmitted through contaminated food or water, contact with an infected person, or contact with contaminated surfaces.
The symptoms of norovirus include vomiting, diarrhea, nausea, and stomach pain. The virus usually lasts for one to three days.
There is no specific treatment for norovirus, but there are ways to relieve the symptoms. Resting and drinking plenty of fluids can help reduce the severity of the illness.
It is important to wash hands thoroughly before eating, after using the bathroom, and after caring for someone who has been sick. People should avoid sharing drinks or eating foods from unapproved sources.
How does it spread?
Norovirus is often spread through contaminated food or water, contact with an infected person, or contact with contaminated surfaces.
The virus can also be spread through the air when an infected person vomits. Treatment focuses on relieving symptoms and preventing dehydration.
There is no specific cure for norovirus, but it usually goes away on its own within a few days.
What are the signs and symptoms of norovirus?
Symptoms of norovirus include diarrhea, vomiting, nausea, and stomach pain. The virus can also cause fever, headache, body aches, and a general feeling of fatigue.
Symptoms usually appear within 12 to 48 hours after exposure to the virus and can last for one to three days. However, some people may have no symptoms at all.
Norovirus is often more severe in young children and older adults because their immune systems are weaker than that of most healthy adults. In addition, it is possible to spread the virus before experiencing any symptoms.
The virus spreads through contact with contaminated surfaces or by touching your mouth while you are carrying the virus and then touching other surfaces or objects.
You can be contagious as long as your feces contain the virus even if you do not have any other symptoms of infection.
How can you treat it?
There is no specific treatment for norovirus, but there are ways to ease your symptoms. Getting plenty of rest, drinking clear fluids like water or broth, and eating bland foods can help you feel better.
In severe cases, you may need to be hospitalized for dehydration. Other complications from the illness include pancreatitis, which can lead to pain in the upper abdomen and loss of appetite.
If you have diabetes or heart disease, call your doctor immediately if you experience these symptoms.
Young children with weak immune systems should also see their doctors quickly if they experience these symptoms.
Babies under 12 months old, pregnant women, and people over age 65 are more likely to get dehydrated because they may not vomit as much as other people.
If you are sick with vomiting and diarrhea for more than 3 days, it's time to contact your healthcare provider so they can determine what's causing the issue and give you appropriate treatment.
What is the best way to prevent norovirus infection?
The best way to prevent norovirus is to practice good hygiene. This means washing your hands regularly, especially after using the bathroom or handling food.
Avoid close contact with people who are sick. Clean and disinfect surfaces that may be contaminated. And finally, don't prepare food for others if you're sick yourself.
When it comes to symptoms, most people experience nausea, vomiting, diarrhea, stomach cramps and fever. If untreated, this can lead to dehydration as well as complications like seizures or kidney failure.
Fortunately though treatment consists of a visit to the doctor where they will administer fluids and antibiotics intravenously in order to shorten recovery time.

The best way to prevent norovirus is to practice good hygiene and wash your hands often. If you think you have norovirus, stay home from work or school until at least 48 hours after the symptoms have stopped.
If you are sick, please use bleach on all hard surfaces to kill the virus before going back into public places. You should also thoroughly clean any kitchenware used during illness.
Food prepared for others should not be served for at least 2 days after symptoms stop.
