Viral gastroenteritis can be highly infectious so it can spread very easily. It spreads when a person comes in contact with the vomit or faeces (poo) of an infected person, including: person-to-person contact, for example shaking hands with someone who has been sick and has the virus on their hands.
If you're anywhere near the splash zone — even just kneeling next to them, without any of the vomit getting on you — virus-laden vomit particles can travel through the air and enter the mucous membranes of your nose or mouth as you breathe.
You can get norovirus by:
Having direct contact with someone with norovirus, such as by caring for them, sharing food or eating utensils with them, or eating food handled by them. Eating food or drinking liquids that are contaminated with norovirus.
Stomach flu is extremely contagious and can spread through person-to-person contact. A person can also catch it after coming into contact with contaminated water or food. Symptoms can pass within 3 days. Stomach flu is one of several ways to refer to viral gastroenteritis.
Stay home when sick and for two days after symptoms stop. Avoid preparing food for others when sick and for two days after symptoms stop.

The ease of transmission of the infection is one reason why when a kid brings it home from school it's common for everyone in the house to come down with it. But, some of you lucky folks rarely become infected, or when you do, experience either very mild or no symptoms at all.
Yes, gastro is contagious
The germs can be spread by the vomit or faeces of an infected person, through hand-to-hand contact (such as shaking hands) or by touching contaminated objects.
The virus is spread by direct or indirect contact with a sick person's stool or vomit. This includes kissing or touching a sick person or coming into contact with contaminated objects, surfaces, or food.
A person with gastroenteritis is most infectious from when their symptoms start until 48 hours after all their symptoms have passed, although they may also be infectious for a short time before and after this.
Why does stomach flu hit at night? In some people, the stomach flu symptoms may be more pronounced at night due to their circadian rhythm. At night an increase in immune system activity releases infection-fighting chemicals. These can cause inflammation that make you feel worse as you battle your flu.
The best way to prevent catching a stomach bug: thorough hand washing. Everyone in your family should wash their hands with soap and water before eating and after using the bathroom. If you have an infant, be sure to follow proper handling and disposal of dirty diapers.
Summary: Noroviruses, a group of viruses responsible for over 50 percent of global gastroenteritis cases, can spread by air up to several meters from an infected person according to a new study.
Sometimes people infected with norovirus have no symptoms at all, but can still pass the virus to others.
Prevention
All of the viruses that cause the stomach bug are highly contagious. Once one person in a daycare, school or office catches it, it's not unusual to see many others also get sick. If your child is healthy and not sick, the most important thing to do is to keep him/her that way.
Another way to catch the stomach flu is by breathing in airborne viruses after an ill person vomits. If the illness is not quickly recognized and steps immediately taken to control it, the infection will spread rapidly from person to person.
If you're exposed to someone sick, wash your hands right away. When caring for someone with norovirus, wash your hands every time you come in contact with the person.
Sleeping in the same bed will increase your chances of contracting your spouse's illness but often can't be avoided, Dr. Thompson said. “You can't move out of the house.” Regularly cleaning counters and frequently touched spots (like the fridge handles) may also cut down on germs.
Symptoms tend to pass after a few days, but norovirus can live on surfaces — and sicken others — for up to two weeks. According to the Centers for Disease Control and Prevention, noroviruses cause anywhere from 19 million to 21 million cases of acute gastroenteritis per year.
You can start to treat when symptoms first appear. See your doctor or pharmacist before taking Gastro-Stop if you have a fever, severe stomach pain, bloody diarrhoea or ongoing condition affecting the bowel.
How long are people contagious? People infected with norovirus are contagious from the moment they begin feeling ill to at least 3 days after recovery.
The person's vomit is then likely to be infectious (i.e. able to infect anyone who comes in contact with the person's vomit). It is for this reason that the person's vomit should be cleaned up, and the surrounding areas decontaminated.
It's possible to catch a cold, flu, or COVID-19 when sleeping in the same bed as someone who is sick. To mitigate your risk, you'll want to sleep in another room (if possible), keep your home well ventilated by opening windows, and wash and disinfect bed linens, pillows, and commonly touched surfaces in your home.
Rule of thumb: if somebody has had the stomach flu in your apartment or dorm, stay out of his or her room for two weeks. If you need to be in a particular place in which a person has vomited, follow the next rule. 10. Clean surfaces with chlorine-based disinfectants.
Susceptibility to norovirus depends on blood type
Your blood type—A, B, AB, or O—is dictated by genes that determine which kinds of molecules, called oligosaccharides, are found on the surface of your red blood cells. Oligosaccharides are made from different types of sugars linked together in complex ways.
