What Should I Know About Stomach Flu?

The stomach flu, or viral gastroenteritis, is a highly contagious infection that inflames the stomach and intestines, causing symptoms like vomiting, diarrhea and stomach cramps. If your child comes down with the stomach flu, understanding what it is, how to manage it and when to seek help can make a big difference in their recovery.

What Exactly Is the Stomach Flu?

Despite its name, the stomach flu is not caused by the influenza virus. In fact, the Mayo Clinic affirms that it typically results from viruses such as norovirus or rotavirus. These viruses attack the digestive tract, causing uncomfortable but usually short-lived symptoms. The stomach flu can affect people of all ages, but it’s especially common—and sometimes more severe—in young children.

How Does the Stomach Flu Spread?

The stomach flu spreads very easily through contact with an infected person’s stool or vomit, or by touching contaminated surfaces and then putting your hands in your mouth. You can also contract it from contaminated food or water. Because it’s so contagious, outbreaks are common in schools, daycare centers and families.

What Are the Main Symptoms of Stomach Flu?

Common symptoms of stomach flu include:

• Sudden onset of nausea and vomiting
• Watery diarrhea
• Stomach pain or cramping
• Fever
• Headache
• Muscle aches

Symptoms usually appear 1 to 3 days after exposure and can last 1 to 10 days, depending on the virus and the individual’s health.

How Is the Stomach Flu Treated?

There’s no specific cure for the stomach flu, but you can help your child recover by focusing on supportive care:

• Keep them hydrated: Small, frequent sips of clear fluids like water or oral rehydration solutions can prevent dehydration.
• Offer bland foods: Once vomiting subsides, gradually introduce bland foods like toast, rice, applesauce and bananas.
• Rest is essential: Let your child rest as much as possible.

Avoid giving over-the-counter anti-diarrheal medications to young children without consulting your pediatrician.

How Can I Prevent the Stomach Flu?
