If your child has gastro, they may: feel unwell, and not want to eat or drink. vomit in the first 24 to 48 hours (usually before diarrhoea begins) have diarrhoea, which can last up to 10 days.

Symptoms are usually brief and last only one or two days. However, during that period, people can feel very ill and vomit, often violently and without warning, many times a day. Symptoms usually begin 24 to 48 hours after ingestion of the virus, but can appear as early as 12 hours after exposure.
Symptoms usually begin 1 or 2 days after ingesting the virus, but may appear as early as 12 hours after exposure. The illness typically comes on suddenly. The infected person may feel very sick and vomit often, sometimes without warning, many times a day.
Although it is most commonly caused by gastroenteritis (sometimes called “stomach flu”), people also deal with vomiting during pregnancy, after taking certain medications, while undergoing cancer treatments, when they have migraine headaches, and several other reasons.
Norovirus infection symptoms usually last 1 to 3 days. Most people recover completely without treatment. However, for some people — especially young children, older adults and people with other medical conditions — vomiting and diarrhea can be severely dehydrating and require medical attention.
COVID-19 gastrointestinal symptoms – Up to one-third of patients with COVID-19 initially present with gastrointestinal rather than respiratory symptoms, most commonly anorexia, diarrhea, nausea or vomiting, and abdominal pain. (See 'COVID-19 gastrointestinal symptoms' above.)
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.
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.
People who may have a stomach virus but are not experiencing vomiting or diarrhea may get better on their own without treatment. It is still advisable to stay hydrated during this time. However, a person should talk with a doctor if they develop any of the following symptoms: severe pain.
Projectile vomiting and stomach cramps are often caused by the norovirus, a type of stomach virus. Stomach viruses take longer to develop but usually go away in about 24 to 28 hours after symptoms begin.
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.
For both norovirus and rotavirus, symptoms typically peak in the first day or two after they begin, and tend to be gone by the third day.
Washing hands with soap and water is the best way to prevent gastroenteritis infection. Alcohol-based hand sanitisers while effective against some viruses (such as coronavirus), are not effective against gastroenteritis. Keep your child away from others until 48 hours after their symptoms have stopped.
People infected with norovirus are contagious from the moment they begin feeling ill to at least 3 days after recovery. Some people may be contagious for as long as 2 weeks after recovery. Therefore, good hand washing is important.
Gastroenteritis is often mistaken for stomach flu although it is actually an inflammation of the lining of the intestines caused by a virus, bacteria or parasites. Symptoms of gastroenteritis include diarrhea, abdominal pain, vomiting, headache, fever and chills.
Stomach flu causes gastrointestinal (GI) symptoms like diarrhea, abdominal cramps and nausea. You might also call it a “stomach bug.” A stomach bug isn't always a virus — sometimes it's bacteria or a parasite — but in any case, the symptoms are similar. You might not be able to tell if your bug is a virus or not.
With gastroenteritis, the main symptoms you probably have are watery diarrhea and vomiting. You might also have stomach pain, cramping, fever, nausea, and a headache. Because of diarrhea and vomiting, you also can become dehydrated.
