Avoid milk and other dairy products as well as undiluted fruit juice, soft-drinks, or sports drinks because the sugar may make the diarrhoea worse. It is fine to eat once you feel like it. If you are very sick with gastro, you may need to go to hospital where you may be given fluids directly through a vein (a “drip”).
In most cases, people with viral gastroenteritis get better on their own without medical treatment. You can treat viral gastroenteritis by replacing lost fluids and electrolytes to prevent dehydration. In some cases, over-the-counter medicines may help relieve your symptoms.
“It's resistant to many common disinfectants,” Hall said. CDC recommends using bleach to kill it, including chlorine bleach or hydrogen peroxide. That's why health departments often require restaurants to use bleach to clean countertops and kitchen surfaces. It's also able to survive being dried out.
Gastroenteritis is a contagious illness. An infected person can transmit the illness as long they have symptoms and up to 2 weeks after they have disappeared. He or she can be contagious even a few weeks after symptoms have subsided.
Gastroenteritis is a common bacterial infection that causes diarrhoea and vomiting - it affects 1 in 5 people in the UK each year of all ages. This infection can be easily spread from person to person through close contact, such as shaking hands or hugging someone who has the virus.
Infection may also be spread in the air when people vomit. In most cases it is spread from a person who has symptoms. Some people can pass on the infection without having symptoms. It is important to continue good hygiene for 48 hours after your symptoms have stopped to avoid passing the virus to other people.
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.
Try to eat small amounts of food frequently if you experience nausea. Otherwise, gradually begin to eat bland, easy-to-digest foods, such as soda crackers, toast, gelatin, bananas, applesauce, rice and chicken. Stop eating if your nausea returns.
Foods to eat include clear broths, crackers, toast, gelatin, bananas, rice and chicken. Avoid certain foods until you feel better. These foods include dairy products, alcohol, caffeine, nicotine, processed foods, and fatty, spicy or highly seasoned foods. Be cautious with medications.

nausea and vomiting that may last a day or two. diarrhoea which usually lasts one to three days, but can last up to ten days. stomach cramps and pain. fever (temperature over 37.5 C in adults and over 38 C in children).
If the gastroenteritis is known or suspected to be caused by norovirus, the exclusion period is 48 hours. If working as a food handler in a food business, the exclusion period should be until there has been no diarrhoea or vomiting for 48 hours.
Get plenty of rest
When you have the stomach flu, your body needs rest in order to fight off the infection. Get plenty of sleep and reduce the amount of activity you normally do during the day. This means lounging on the couch when you're not in bed.
If you feel like you're going to throw up, sleep on your side with your head elevated. Sleeping on your side with your head raised can ease symptoms and keep you from choking on your vomit, if you're unable to make it to the bathroom in time.
With norovirus — the most common cause of viral gastroenteritis in adults — you're contagious when you begin to feel ill. Symptoms usually appear within one to two days of exposure. Although you typically feel better after a day or two, you're contagious for a few days after you recover.
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.
Norovirus is spread fecally -- in the poop -- and that means it can get into laundry. Studies show that fecal matter spreads even in ordinary laundry, so if someone is sick, it's important to use very hot water and bleach to destroy virus that could be on any clothing, sheets or towels.
Viral gastroenteritis is contagious. It can be spread from one person to another in the following ways: Close contact with someone who has viral gastroenteritis, e.g. sharing food, drinks, utensils, kissing. Touching a surface that has been contaminated by someone with viral gastroenteritis and then touching your mouth.
While 24 hours may be appropriate for many people, a specific 48-hour exclusion rule is considered necessary for those in a higher-risk category for spreading gastro to others.
Testing data from NSW Health shows that the number of rotavirus cases, the most common cause of gastroenteritis, is at some of the “highest levels of the last decade”. The first two weeks of 2023 saw 197 cases of rotavirus reported, up significantly from the average 40 cases in the same period.
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.
"There are some symptoms more specific to COVID-19, like loss of taste and smell, cough, or chest pains," explained Dr. Elliott, adding, "Patients do not generally get these symptoms with the stomach flu."
