Every winter across the North Shore. In schools, offices, hockey locker rooms, and coffee shops, one phrase starts making the rounds: “There’s a stomach bug going around.” In most cases, that “bug” is norovirus, a microscopic powerhouse of contagiousness that causes sudden vomiting, diarrhea, stomach cramps, and a general feeling of being wrung out. Norovirus isn’t the flu (influenza); it’s a gastrointestinal virus that spreads by tiny particles, often from hands, surfaces, food, and water.

The good news? With innovative prevention and a calm plan for the first 24–48 hours, most people recover at home. Still, dehydration can sneak up, especially in children, older adults, and anyone with chronic conditions. This guide walks you through how norovirus spreads, how to clean properly, what to drink and howto drink it, what to avoid, and the red flags that mean it’s time to visit AFC Urgent Care Beverly. We’re open seven days a week at five convenient locations in MA: Beverly, Swampscott, North Andover, Methuen, and Haverhill. Find directions here: AFC Urgent Care Beverly.

Norovirus 101: Why It’s So Contagious

• Low infectious dose: It takes very few viral particles to infect someone.
• Hardy on surfaces: Norovirus can survive for days on hard surfaces and is resistant to many common cleaners.
• Multiple routes of spread: Person-to-person, contaminated food (think potlucks/buffets), and droplets from vomiting.
• Short incubation: Symptoms often begin 12–48 hours after exposure.
• Burst of symptoms: Sudden vomiting, watery diarrhea, stomach cramps, sometimes fever, headache, muscle aches.

Most people recover in 1–3 days, but dehydration risk is real, especially for children, older adults, and those with chronic illness.

Prevention that Actually Works

Hand Hygiene: Soap, Not Just Sanitizer

• Wash with soap and water for 20 seconds, especially after bathroom use, diaper changes, and before preparing or eating food.
• Alcohol-based sanitizers are only moderately effective against norovirus; use them only as a backup, not a replacement.

Kitchen and Food Safety

• Rinse produce thoroughly.
• Cook shellfish thoroughly; avoid raw oysters during outbreaks.
• Sick-day kitchen rules: Anyone with vomiting or diarrhea should not prepare food for others until at least 48 hours after symptoms stop.

Surface Disinfection: Use the Right Product

• Clean first with a detergent/soapy water solution, then disinfect with a bleach solution (1000–5000 ppm; roughly 5–25 tablespoons of household bleach per gallon of water) or an EPA-registered disinfectant labeled effective against norovirus.
• Focus on high-touch spots: faucets, door handles, light switches, remote controls, toilet flush handles, and countertops.
• Soft surfaces: Launder contaminated linens and clothing in hot water; handle soiled items carefully to avoid aerosolizing particles.

School, Sports, and Work

• Encourage kids to wash their hands at school and avoid sharing water bottles or snacks.
• Wipe down shared equipment (desks, weight-room handles).
• Stay home if you’re ill; return 48 hours after last symptoms.

Home Care: The First 24–48 Hours

Rehydration: Small, Frequent, Strategic

• The goal is to prevent dehydration while your gut recovers.
• Start with small sips every 5–10 minutes: oral rehydration solutions (ORS), diluted sports drinks, broths, or electrolyte ice chips.
• For kids, ORS (Pedialyte-style) is ideal. Avoid full-strength juice or soda early in the day, as they can worsen diarrhea.

Eating: Gentle and Gradual

• Once vomiting eases, begin bland, low-fat foods: plain crackers, toast, rice, bananas, applesauce, plain pasta, potatoes, eggs.
• Add lean proteins (such as eggs, chicken, and turkey) and simple soups, as tolerated.
• Avoid greasy, spicy, or high-fiber foods for the first few days.
• Dairy may temporarily worsen symptoms in some people; reintroduce it slowly.

Medications: What Helps, What to Skip

• Acetaminophen for fever/aches (follow age/weight dosing).
• Avoid NSAIDs (ibuprofen or naproxen) on an empty, irritated stomach if possible, as they can worsen GI irritation.
• Anti-diarrheals: In adults, loperamide may help if diarrhea is severe and there’s no fever or blood in the stool. Avoid anti-diarrheals in children unless a clinician recommends them.
• Antibiotics don’t treat viruses and can worsen diarrhea.

Cleaning Up After Vomiting or Diarrhea: Step-by-Step

1. Protect yourself: wear disposable gloves, wear a mask if available, and ensure good ventilation.
2. Contain the mess: Absorb with paper towels; avoid splashing.
3. Clean the area with soap/detergent and water.
4. Disinfect with bleach solution (1000–5000 ppm) or an EPA-registered norovirus disinfectant; keep the surface wet for the labeled contact time.
5. Dispose of waste carefully; bag and tie securely.
6. Launder contaminated fabrics in hot water; dry them thoroughly.
7. Wash your hands with soap and water immediately after.

Norovirus vs. “Food Poisoning”: What’s the Difference?

• Timing: Many foodborne illnesses begin within hours; norovirus typically occurs 12–48 hours after exposure.
• Symptoms: Overlap is significant, with vomiting, diarrhea, and cramps.
• Clues: If several people who shared a meal become ill at the same time, suspect a foodborne outbreak (which can also be norovirus).
• Care: Supportive hydration is essential for both. Seek care for dehydration, bloody stools, or high fever.

Travel, Workplaces, and Schools: Practical Prevention

• Travel: Wipe airplane tray tables and armrests; wash hands before eating; stick to sealed beverages and hot foods.
• Work: Keep sanitizer handy, but prioritize handwashing; don’t share mugs or utensils.
• Schools/Childcare: Enforce “48-hour symptom-free before return” after stomach illness; daily disinfection of bathrooms and high-touch areas.

Special Populations

Older Adults

There is a higher risk for dehydration and electrolyte imbalance. Encourage early ORS, monitor urine output, and seek care sooner for persistent symptoms.

People with Chronic Illness (Diabetes, Kidney, Heart Disease)

Illness can disrupt medications and fluid balance. Contact a clinician early; bring medication lists to urgent care.

Pregnant People

Hydration is vital. Seek evaluation sooner for persistent vomiting or signs of dehydration.

Frequently Asked Questions

Is norovirus the flu?

No. Influenza is a respiratory virus; norovirus primarily affects the stomach and intestines.

How long am I contagious?

You’re most contagious when sick and for at least 48 hours after symptoms stop. Some people shed the virus for days to weeks; strict hygiene matters.

Should I use probiotics?

Some find probiotics help restore gut balance after illness. They’re generally safe for healthy adults; ask your clinician if you’re immunocompromised.

Can I take antibiotics “just in case”?

No, norovirus is viral. Antibiotics don’t help and can worsen diarrhea.

When can I work or send my child to school?

Return once symptom-free for 48 hours and able to maintain hydration and regular activity.
