What you need to know about norovirus

As we settle into winter, most of us are on alert for colds and the flu, but stomach bugs deserve a spot on that list, too. Norovirus has a habit of popping up more frequently this time of year, mostly because we’re all indoors more and sharing spaces more closely.  

This virus can spread through the tiniest bits of contamination on hands, surfaces, food or water, which makes places like schools, care facilities and travel hubs easy spots for it to circulate. And just when someone starts feeling better, they can still pass it along for quite a while, so it’s no surprise outbreaks can take off quickly.  

The good news? A little awareness goes a long way in keeping your family healthy through the season. Learn more from Dr. Judith Philip, family medicine physician at Beacon Medical Group WaNee.  

What is norovirus?
Norovirus is a highly contagious virus that causes stomach upset, including nausea, vomiting, diarrhea and stomach cramps. Symptoms often appear suddenly, usually within a day or two of exposure, and most people feel better within a few days. While the illness is often short‑lived, it can be especially uncomfortable and disruptive for families. 

How does norovirus spread?
Norovirus spreads through tiny particles that can be picked up from contaminated hands, surfaces, food or water. Because only a small amount of the virus is needed to cause illness — and because people can still spread it even after they start feeling better — it can move quickly through households, schools and other shared spaces. 

Who is most likely to catch it?
Common places where norovirus spreads include schools and daycares, long‑term care facilities, restaurants, travel settings like airports or cruise ships, and anywhere people are sharing close quarters or frequently touched surfaces. And while exposure may happen in many shared spaces, the risk of serious illness isn’t the same for everyone. 

 “Young children under 5 and adults over 65 are at increased risk for severe illness, especially if they have weakened immune systems or chronic health conditions,” Dr. Philip said. “Norovirus infections are more common in children, but older adults are more likely to become seriously ill.” 

How can you protect yourself and your family?
Dr. Philip shares the small steps that can make a difference for families trying to stay healthy this season:  

• Wash hands thoroughly with soap and water. Hand sanitizers DO NOT work well against norovirus.  

• Clean and disinfect surfaces. 

• Wash fruits and vegetables before eating.  

• If you are sick, do not prepare food or care for others for at least 48 hours after you feel better.  

What if someone at home gets sick?
If norovirus hits your household, focus on preventing its spread and supporting recovery: 

• Keep the sick person separate when possible. 

• Clean up accidents promptly using gloves and disinfectants. 

• Wash soiled clothing and linens right away. 

• Encourage small, frequent sips of fluids to help prevent dehydration. 

 “Most individuals recover without treatment; however, staying well-hydrated is important to replace fluids lost from vomiting and diarrhea,” Dr. Philip added. 

A final word
While norovirus is common during winter, awareness and good hygiene go a long way. Simple habits like proper handwashing and staying home when ill can help protect not just your family, but your entire community.
