What Causes Stomach Virus In Adults

Keys To Preventing Spread Of Viral Gastroenteritis

Symptoms of Gastroenteritis
  • Washing hands for 20 seconds with soap and water, especially: after changing a diaper, after going to the bathroom, before preparing food, and before eating.
  • Avoiding touching the face with unwashed hands.
  • Don’t share food or utensils with other people.
  • Dispose of dirty diapers or other items with stool on them with care.
  • Avoid close contact with people who are already ill.
  • After an illness, clean surfaces that may have the virus on them with detergent and chlorine bleach.
  • Don’t prepare any food for other people until at least 2 or 3 days after diarrhea/vomiting stops.
  • Don’t eat food that is prepared by someone who is ill with diarrhea/vomiting.
  • Stay home and away from other people when ill.

The fecal-oral route tends to make most people cringe because it implies close contact between stool or feces and the face. Not washing hands well is usually how the viruses that cause illnesses are spread.

However, its important to remember that the viruses that cause illness are spread quite easily, especially in daycare centers, schools, or adult care facilities. Those who care for children and adults who wear diapers, especially, need to take care to wash hands carefully with soap and water. Babies and children should have their hands washed often, especially if they are touching their diaper area.

When To Call Your Healthcare Provider

Most people can manage rotavirus on their own, but in some cases, professional medical care is necessary.

  • A fever over 100 degrees
  • A fever lasting for longer than three or four days
  • You feel like you cannot keep down any water or food
  • Blood in your stool or dark-colored stools
  • Vomiting blood
  • Very little or no urine
  • A weak or rapid heartbeat
  • Very dry mouth
  • Cool sensation in your arms and legs
  • Difficulty breathing
  • Difficulty walking or standing

Why Rotavirus Can Be Serious

Elderly adults and those with a compromised immune system due to illness or chemotherapy can lose their immunity to the virus and are more susceptible to becoming very ill as a result of gastroenteritis.

You may encounter different strains of rotavirus that you are not immune to when you travel, which can cause you to become very sick.

Do you know what the Centers for Disease Control and Prevention say about how to get rid of stomach flu caused by the norovirus? According to the CDC:

In some cases, your doctor may recommend probiotics. Probiotics are live microbes, most often bacteria, that are like the ones you normally have in your digestive tract.

Is Stomach Flu Contagious

Viral stomach flu spreads easily to others. You can catch a stomach flu virus any time of the year, but the common norovirus is more widespread from November to April when people tend to be more indoors. Because a variety of viruses can cause stomach flu, you might get different versions of gastroenteritis many times throughout life.

Its spread from person to person by coming into contact with tiny, invisible particles from a sick persons stool or vomit if you:

  • Touch a surface and come in contact with the germs and you touch food or your mouth.
  • Eat or drink food or beverages that have a sick persons germs.
  • Have close contact with someone who has stomach flu .

Antibiotics For Bacterial Gastroenteritis

In mild cases of bacterial gastroenteritis, antibiotics are typically not considered necessary and will not be prescribed. Antibiotic medication is generally only recommended in severe or persistent cases of bacterial food poisoning, in some cases of travelerâs diarrhea, in infections with C. difficile and in cases where the person has a weakened immune system or is otherwise at risk of complications. The type of antibiotics needed will depend on the specific type of bacteria, which may need to be determined with laboratory tests.

What Are The Causes Of Gastroenteritis In Children

The causes of gastroenteritis in children are :

  • Viral infection: Most viral gastroenteritis is caused by rotavirus, adenovirus, or norovirus . In the UK, every child below five years gets a rotavirus infection. Children become immune to this virus after the first infection. Adenovirus and rotavirus infections are more common in infants and children than in teenagers. Norovirus mostly infects older children and adults .
  • Bacterial infection: Bacterial species such as Campylobacter, Salmonella, and Escherichia produce toxins that may cause food poisoning.
  • Parasitic infection: Parasites live on or inside another organism, causing parasitic infection, which may also cause food poisoning.
  • Water contamination: Gastroenteritis may also occur if bacteria or other microbes contaminate the water. This usually occurs in countries with poor sanitation.
  • The germs causing gastroenteritis may spread easily if children

    • Eat food after touching a contaminated object
    • Live with an infected person

    When Do I Need To See A Doctor


    You need to seek medical advice if you think you are becoming dehydrated, you’re throwing up a lot and can’t keep fluids down, you have blood in your poo or sick , or you have severe tummy pains. A persistent high temperature or diarrhoea or puking that lasts longer than expected are other reasons to contact the doc. Also, if you’re elderly, have a long-term condition such as diabetes, are pregnant or have trouble with your immune system, don’t hesitate to get in touch with a health professional.

    Gastroenteritis is common. About 1 in 5 people in the UK will develop an episode of gastroenteritis in a year.

    Most people have a mild form of gastroenteritis and do not need to seek medical advice or to visit their doctor.

    • The main symptom is diarrhoea, often with being sick as well. Diarrhoea means loose or watery stools , usually at least three times in 24 hours. Blood or mucus can appear in the stools with some infections.
    • Crampy pains in your tummy are common. Pains may ease for a while each time you pass some diarrhoea.
    • A high temperature , headache and aching limbs sometimes occur.

    If vomiting occurs, it often lasts only a day or so but sometimes longer. Diarrhoea often continues after the vomiting stops and commonly lasts for several days or more. Slightly loose stools may continue for a week or so further before a normal pattern returns. Sometimes the symptoms last longer.

    Is A Stomach Virus Contagious

    Yes, a stomach virus can be contagious. Sick people who do not wash their hands before preparing food can spread the stomach flu to others. Stomach viruses are contagious because viruses and bacteria can live in or on food.

    If the food is handled or cooked improperly, you have a greater risk of catching the stomach flu. Cross-contamination during cooking also causes stomach viruses to spread. This can happen when a person uses the same cutting board or knife to prepare different foods.

    When To Seek Medical Help For Gastroenteritis

    Most people with gastroenteritis get better at home without seeing a doctor. But contact your GP if you:

    • are being sick a lot and cant keep down any fluids

    Bacterial Gastroenteritis Caused By Exotoxins

    Some cases of bacterial gastroenteritis are not caused by bacteria themselves, but instead by toxins that they release. The harmful byproducts of certain types of bacteria can contaminate food, causing a type of food poisoning when ingested. These byproducts are called exotoxins, and they usually cause symptoms within 12 hours of consuming the contaminated food. This type of gastroenteritis typically clears up within 36 hours.

    Your GP may suggest sending off a sample of your child’s poo to a laboratory to confirm what’s causing their symptoms. Antibiotics may be prescribed if this shows they have a bacterial infection.

    How Can I Prevent Viral Gastroenteritis

    You can take several steps to keep from getting or spreading infections that cause viral gastroenteritis. Wash your hands thoroughly with soap and water

    • after using the bathroom
    • after changing diapers
    • before and after handling, preparing, or eating food

    You can clean surfaces that may have come into contact with infected stool or vomit, such as countertops and changing tables, with a mixture of 5 to 25 tablespoons of household bleach and 1 gallon of water.7 If clothes or linens may have come into contact with an infected persons stool or vomit, you should wash them with detergent for the longest cycle available and machine dry them. To protect yourself from infection, wear rubber gloves while handling the soiled laundry and wash your hands afterward.7

    If you have viral gastroenteritis, avoid handling and preparing food for others while you are sick and for 2 days after your symptoms stop.7 People who have viral gastroenteritis may spread the virus to any food they handle, especially if they do not thoroughly wash their hands. Contaminated water may also spread a virus to foods before they are harvested. For example, contaminated fruits, vegetables, and oysters have been linked to norovirus outbreaks. Wash fruits and vegetables before using them, and thoroughly cook oysters and other shellfish.7Find tips to help keep food safe.
