A rapid stool test can detect rotavirus or norovirus, but there are no quick tests for other viruses that cause gastroenteritis. In some cases, your doctor may have you submit a stool sample to rule out a possible bacterial or parasitic infection.
Gastroenteritis typically lasts in the neighborhood of three to seven days, but sometimes it can be shorter and, unfortunately, sometimes it lasts longer.
How is gastroenteritis diagnosed? Your healthcare provider will perform an exam and ask about your medical history. Your healthcare provider will likely ask for a stool sample to determine the source of your illness and whether it's bacterial or viral.
Labs and Tests
There's not any specific test that can be used to make a diagnosis of the stomach flu. Instead, a complete medical history and a physical exam will be done, which will likely be enough to make a presumptive diagnosis.
However, the key distinction is time: The symptoms of a stomach bug will take 12 to 48 hours to develop, while the symptoms of food poisoning typically develop much faster, usually with 6 hours of consuming an infected dish. Another common difference between the two is the length of illness.
Your doctor may prescribe medicine to control severe vomiting. Doctors don't prescribe antibiotics link to treat viral gastroenteritis. Antibiotics don't work for viral infections. In some cases, your doctor may recommend probiotics link.
Most cases of the stomach flu can be treated at home. However, if you have symptoms such as a high fever, severe abdominal pain, inability to keep liquids down, or vomit or diarrhea lasting more for two days, it's important to seek medical care.
The initial stages start with chills, fever, and nausea, which transition into vomiting, diarrhea, and aches and pains. It's awful, and there is no cure. Stomach flu has to run its course. The sickness usually passes in about 10 days without medication.

A viral infection that attacks the digestive system is commonly called a stomach virus. People sometimes call the illness a 'stomach flu', although this name is misleading, as influenza attacks the respiratory system. A stomach virus can also be known as viral gastroenteritis. Different strains of the virus exist.
Can I catch viral gastroenteritis from someone? Yes, viral gastroenteritis is contagious. It is spread through close contact with infected persons (for example, by sharing food, water, or eating utensils) or by touching surfaces contaminated by an infected person and then touching one's mouth.
When to Call a Doctor. Get medical help if you're vomiting and can't keep any liquids down for longer than 24 hours, or you have diarrhea for more than a couple of days (24 hours for children). Signs of dehydration include excessive thirst, dry mouth, deep yellow urine or little or no urine, and severe weakness.
Stay off school or work until you've not been sick or had diarrhoea for at least 2 days. If you also have a high temperature or do not feel well enough to do your normal activities, try to stay at home and avoid contact with other people until you feel better.
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.
In many cases, throwing up is a protective reflex to rid your body of viruses, bacteria, or parasites in your digestive system.
What are the symptoms? Common symptoms of norovirus infection include vomiting, diarrhea, and stomach cramping. Less common symptoms can include low-grade fever or chills, headache, and muscle aches. Symptoms usually begin 1 or 2 days after ingesting the virus, but may appear as early as 12 hours after exposure.
Nausea, vomiting and diarrhea are less common symptoms of COVID-19. Still, when they do occur, they tend to be some of the first symptoms you will experience. Diarrhea caused by COVID-19 tends to be more watery, yellow or green in color. It may be accompanied by cramping and bloating.
A 24-hour stomach bug is a viral infection that causes diarrhea and vomiting. Most cases are easily treatable and resolve in one to three days. Sometimes called the "stomach flu," the 24-hour stomach bug is a type of gastroenteritis caused by a contagious infection like norovirus.
Unlike viral gastroenteritis, food poisoning is strictly based on what you eat. It can be caused by bacteria, parasites and viruses. And just like with the stomach flu, you may experience the same symptoms of nausea, vomiting, diarrhea, abdominal cramping and fever.
