Facts of Norovirus
* Norovirus is a small virus that is highly contagious among humans.
* People get the virus by eating things contaminated with a small amount of infected feces or fluids. Food and water may be contaminated during processing or handling. (Norovirus Treatment)
* Norovirus is the most common cause of gastroenteritis in the United States.
Signs and symptoms of norovirus infection include
* Hitting and / or
* Watery diarrhea.
* Illness usually lasts two to three days and resolves on its own.
* There is no specific treatment for norovirus, but it is important that people with the virus stay hydrated. (Norovirus Treatment)
Liquids containing sugar and electrolytes should be encouraged. Intravenous fluids may be needed if a person is unable to store enough fluid orally.
* Problems are usually related to dehydration. Young children and adults are especially at risk of dehydration.
* Because the disease is highly contagious, it is important for caregivers to wash their hands whenever they come in contact with the patient or his or her environment. (Norovirus Treatment)
* The risk of foodborne illness or outbreak in hospitals or nursing homes may be reduced by following standard procedures that include hand hygiene; soap and water are recommended, as alcohol-based hand sanitizers do not work well against noroviruses. (Norovirus Symptoms)
What is a norovirus ?
Norovirus is a small virus that contains RNA and is surrounded by protein coating. By sequencing RNA, scientists have discovered that there are many different types of norovirus.
Initially, the species were named based on the city in which they were first identified. Thus, one common form was called the Norwalk virus.
Based on genetic typing, we now know that there are at least 25 different types of norovirus that affect humans.
The RNA genome in noroviruses easily mutates to produce new species of norovirus. The disease occurred worldwide with a high incidence from November to the end of May in the U.S. Therefore, the infection is sometimes referred to as “winter vomiting disease.”
Norovirus infection is the most common cause of outbreaks of gastroenteritis in the U.S. Although some people call this “stomach flu,” norovirus is not related to the flu virus. (Norovirus Treatment)
According to statistics from the U.S. Centers for Disease Control and Prevention (CDC), there are 19-21 million cases of norovirus infection annually in the U.S., where one quarter of them are related to an outbreak. (Norovirus Symptoms)
The annual Norovirus infection causes 570-800 deaths in the U.S., especially in young children and the elderly.
Outbreaks appear to be exacerbated during the year but are most common during the winter months.
There is no specific treatment for norovirus. Fortunately, the disease is self-limiting, and simple supportive measures are sufficient to care for most people unless they are dehydrated.
Norovirus outbreaks can occur almost anywhere in the world. In 2012, a new type of GII was discovered in Sydney. Since the outbreak began, the virus was quickly identified in New Zealand, France, and the US. (Norovirus Symptoms)
A new norovirus outbreak occurred in Yellowstone National Park, infecting about 200 visitors and camp staff in June 2013.
A new form of norovirus has been developed. found in southern China and designated as GII.17. Unfortunately, the virus has changed enough that many people will not be protected even if they have been infected with norovirus in the past.
Outbreaks appear to be exacerbated during pregnancy. In 2015, an outbreak of shipwreck on ships, in restaurants and in schools.
For example, the Star Princess cruise ship had at least two separate outbreaks that killed hundreds of people in 2015.
In August 2015, 98 customers and 17 employees became ill as a result of a norovirus outbreak on the Chipotle Mexican Grill in Simi Valley, Calif.
The outbreak also occurred in 17 schools in the Nevada school district where more than 1,145 people have so far developed norovirus infection since October 2015.
The most recent outbreak occurred in England where in one week, there was a 70% increase in -norovirus to many. as many as 1,336 people were hospitalized for norovirus in December 2017.
Removal of contaminants of areas (see prevention section below) and potential contaminants is important as researchers have shown that only 10-20 viral particles are needed to cause infection.
Signs and symptoms of norovirus infection include:
* Abdominal pain or cramps
* Watery or loose diarrhea
* Feeling sick
* Low-grade fever
* Muscle pain
Signs and symptoms usually begin 12 to 48 hours after exposure to norovirus and last for one to three days.
You can continue to shed the virus in the wild for up to two weeks after recovery. This depletion can take weeks to months if you have a subtle health condition.
Some people with norovirus infection do not show any signs or symptoms. However, they are still contagious and can spread the virus to others. (Norovirus Treatment)
Noroviruses are highly contagious and are transmitted to the wild by infected humans and animals. You can get a noro virus by:
* Eating unclean food
* Drinking dirty water
* Touching your hand to your mouth after your hand has touched a dirty area or thing
* Close contact with a person with a norovirus infection
Noroviruses are difficult to kill because they can withstand hot and cold temperatures and many antibiotics.
Noro virus Risk factors
Risk factors for noro virus infection include:
* Food in an area where food is handled improperly
* Attending preschool or a child care center
* Living in close quarters, such as in nursing homes
* Accommodation in hotels, resorts, cruise lines or other crowded places
* Contact with a person with a noro virus infection. (Norovirus Symptoms)
There is no prescriptive drug that will stop the flow of emotions, though their effects can be curtailed. Noro virus infection cannot be treated with antibiotics because it is a virus.
Treatment is aimed at avoiding problems with measures such as dehydration caused by dehydration during diarrhea and diarrhea, as well as reducing symptoms with anti-inflammatory drugs and anti-diarrheal drugs. (Norovirus Symptoms)
For most people, the noro virus infection usually disappears within a few days and does not endanger lives. But for some people – especially children, the elderly and people with compromised immune systems – the noro virus infection can cause dehydration.
Noro virus infection can cause dehydration, malnutrition and even death, especially in the elderly or infirm, or in pregnant women. (Norovirus Symptoms)
Warning signs of dehydration include:
* Dry mouth and throat
* Lack of listing
* Urinary incontinence
Dehydrated babies may shed a few tears or not at all. They may have abnormal sleep or fights. (Norovirus Symptoms)
How to prevent Norovirus
Noro virus infections are highly contagious, and anyone can be infected more than once. To help prevent its spread:
- Wash your hands thoroughly with soap and water, especially after using the toilet or changing a nappy.
- Avoid contaminated food and water, including food that may be cooked by someone who is ill.
- Wash fruits and vegetables before eating.
- Cook seafood well.
- Dispose of cleaning and sanitation carefully to avoid spreading the norovirus through the air.
- Wrap the material in disposable towels, wrap it around as little as possible, and place it in disposable plastic bags.
- Disinfect areas that may be contaminated. Use a solution of chlorine bleach and wear gloves.
- Stay home from work, especially if your job involves handling food. You may become infected three days after your symptoms disappear.
- Children should stay home and not go to school or take care of children.
- Avoid walking until your symptoms are gone.
