Norovirus is back—here’s what parents need to know.
If your child suddenly started vomiting with little to no warning, you’re not imagining things: a stomach bug is going around right now, and it’s usually norovirus (though there are other viruses that can cause similar symptoms).
Norovirus is extremely contagious. It spreads through close contact, contaminated surfaces, and even tiny droplets when someone vomits. That’s why it moves so fast through families, schools, and daycare settings.
Symptoms usually come on quickly: vomiting, diarrhea, stomach cramps, sometimes fever—and kids often feel pretty miserable for 24 to 72 hours.
Here’s an important thing many parents don’t realize: hand sanitizer doesn’t work well against norovirus. Soap and water are much more effective, especially after bathroom use and before eating.
The biggest risk with norovirus is dehydration, especially in babies and young children. Small, frequent sips of fluids are better than large amounts at once. Oral rehydration solutions are ideal, but even ice chips or teaspoons every few minutes can help.
Avoid anti-diarrheal medications in young kids unless advised by a pediatrician.
Call your pediatrician or seek care if your child:
-Isn’t peeing much
-Can’t keep fluids down
-Has signs of severe dehydration
-Or seems unusually lethargic
The good news? Most kids recover fully with supportive care.
It’s exhausting, but it does pass.
And when in doubt, check in with your pediatrician for guidance and reassurance.
