As a mother of 4 children, I agree...stomach bugs are the worst! If it feels like everyone has a stomach bug lately, you’re not imagining it. Viral gastroenteritis—often called a “stomach bug”—is very common in children, especially during the fall and winter months. Thankfully, most kids recover just fine with a little patience and supportive care at home.
Here's what your pediatrician wants parents to know.
What Is a Stomach Bug?
A stomach bug is usually caused by a virus (most commonly norovirus or rotavirus) that leads to:
Vomiting
Diarrhea
Stomach cramps
Sometimes fever, headache, or body aches
Antibiotics do not help because these infections are viral, not bacterial.
How Do Kids Catch It?
Stomach bugs are extremely contagious. They spread through:
Close contact with an infected person
Touching contaminated surfaces (toys, doorknobs, bathroom fixtures)
Eating food prepared by someone who is sick
Kids can shed the virus even after symptoms improve, which is why outbreaks move quickly through households, schools, and daycare.
How Long Does It Last?
Most children:
Vomit for 24–48 hours
Have diarrhea for several days (sometimes up to 2 weeks)
Energy and appetite may take a little longer to return to normal—and that’s okay.
What Should Parents Do at Home?
The main goal is hydration
Helpful tips:
Offer small, frequent sips of fluids (oral rehydration solution (Pedialyte) is best)
Start with clear liquids if vomiting is active
Let kids eat when they’re ready—simple foods are fine, but don’t force it
Breastfed babies should continue nursing
You don’t need to follow a strict “BRAT(Bananas-Rice-Applesauce-Toast) diet.” Kids can return to their normal diet as tolerated.
When Should You Call the Pediatrician?
Reach out if your child has:
Signs of dehydration (dry mouth, no tears, fewer wet diapers or decreased urine output, dizziness)
Persistent vomiting or diarrhea
Blood in stool or vomit
Severe abdominal pain
Fever lasting more than a few days
Symptoms in infants under 6 months
Trust your instincts—if something doesn’t feel right, it’s always okay to check in.
How Can We Prevent the Spread?
Prevention is tough, but a few steps help:
Wash hands with soap and water (hand sanitizer doesn’t kill all stomach viruses)
Clean high-touch surfaces with disinfectant
Keep sick children home until symptoms resolve
Avoid sharing cups, utensils, or towels
Stomach bugs are miserable—but usually short-lived. With good hydration, rest, and a little TLC, most kids bounce back quickly. And if you’re unsure or need guidance, your pediatrician is always here to help.
