Viruses & Infections
Norovirus
A very contagious virus that causes sudden vomiting and diarrhea, usually clearing in a few days.
Also known as: Winter vomiting bug, Stomach flu (norovirus), nausea (definition: feeling of sickness or urge to vomit)
📝 At a glance
Likely root causes: Swallowing the virus from contaminated hands, food, or water; Close contact with someone who is sick; Touching infected surfaces, then the mouth.
First thing to try: Rest and let the stomach settle; don't force food while vomiting is active.
See a doctor if: Signs of dehydration: very dry mouth, little or no urine, dizziness, sunken eyes
🔎 Start with the cause
Lasting relief rarely comes from covering a symptom. First find what is feeding the problem, change what you can, and then help the body do what it was designed to do — heal.
Likely root causes
- Swallowing the virus from contaminated hands, food, or water
- Close contact with someone who is sick
- Touching infected surfaces, then the mouth
- Eating food handled by an infected person, especially raw shellfish
Change what you can
- Rest and let the stomach settle; don't force food while vomiting is active.
- Once vomiting eases, take small, frequent sips of water or an oral rehydration drink to replace lost fluids.
- Reintroduce bland foods slowly: plain toast, rice, bananas, and broth.
- Wash hands well with soap and water after the bathroom and before eating; gels alone are not enough.
- Stay home and avoid preparing food for others for at least two days after you feel better.

This is the safest, foundational supportive step alongside medical care if needed — norovirus has no specific medicine, so hydration is what protects you most.
How to do it ▾
Why it works: Norovirus causes fluid loss through vomiting and diarrhea; small, frequent sips (rather than large gulps) are easier for an upset stomach to tolerate and help restore lost fluids and salts.
- Rest and avoid forcing food while vomiting is active.
- Once vomiting eases, take small sips of water or oral rehydration solution every few minutes.
- Gradually add clear broths and, when tolerated, bland foods like plain toast, rice, or bananas.
- Continue rehydrating for a day or two after symptoms ease, since fluid losses continue.
until symptoms resolve, usually 1-3 days · small sips every 10-15 minutes while awake
Caution: Watch closely for dehydration, especially in young children and older adults, since it can develop quickly. Antibiotics do not treat norovirus, since it is a virus, not bacteria — avoid taking antibiotics for it.
When to get help: Seek medical care for signs of dehydration (very dry mouth, little or no urination, dizziness, sunken eyes), vomiting that won't stop for more than a day, blood in vomit or stool, or high fever.

An essential companion habit to protect others, since norovirus spreads so easily even after you start feeling better.
How to do it ▾
Why it works: Norovirus survives well on hands and surfaces and resists many hand sanitizers; thorough soap-and-water handwashing and bleach-based disinfecting physically remove or kill the virus, breaking the chain of spread.
- Wash hands with soap and water for at least 20 seconds after using the bathroom, changing diapers, and before eating or preparing food.
- Use soap and water rather than relying on alcohol-based hand sanitizer alone, since it is less effective against norovirus.
- Clean and disinfect contaminated surfaces and doorknobs with a bleach-based cleaner.
- Wash soiled laundry in hot water and stay home from work, school, or food preparation for at least two days after symptoms stop.
ongoing during and after illness · after every bathroom visit and before eating
Caution: You can still spread norovirus for two weeks or more after feeling better, so keep up hygiene habits past the point of feeling well. Avoid preparing food for others while sick and for at least two days after symptoms stop.
When to get help: Seek care if a household member develops signs of dehydration or symptoms lasting more than a few days despite careful hygiene and hydration.

A gentle step once the worst of the vomiting has passed, supporting recovery alongside hydration and rest.
How to do it ▾
Why it works: A recovering gut lining digests simple, low-fat, low-fiber foods more easily than rich or spicy foods, reducing the chance of further stomach upset while healing continues.
- Wait until vomiting has eased before reintroducing any food.
- Start with small amounts of plain foods: toast, crackers, rice, or bananas.
- Add broths and other bland foods gradually as they're tolerated.
- Avoid dairy, caffeine, alcohol, and greasy or spicy foods until fully recovered.
1-3 days as symptoms resolve · small amounts every few hours
Caution: Reintroducing food too quickly or in large amounts can restart vomiting. Children and older adults should be watched closely for tolerance of reintroduced foods and for dehydration.
When to get help: Seek care if food reintroduction consistently triggers vomiting, or if any dehydration signs appear.

“Disease is an effort of nature to free the system from conditions that result from a violation of the laws of health... In case of sickness 1cause should be ascertained, 2go to work intelligently to remove the disease. 3Unhealthful conditions should be changed, 4wrong habits corrected. 5Then nature is to be assisted in her effort 6to expel impurities and 7to re-establish right conditions in the system.”
🌿 Overview
Norovirus is the most common cause of sudden stomach upset that sweeps through families, schools, and cruise ships. It spreads easily, so careful handwashing matters, but for most healthy people it passes on its own within one to three days. The main danger is losing too much fluid, so the goal is gentle rest and steady sips.
Norovirus is a tough, highly contagious virus that inflames the stomach and intestines. It spreads through tiny amounts of infected stool or vomit on hands, food, surfaces, or in the air after someone is sick, and it takes only a few viral particles to pass it on. Symptoms come on fast, often within a day of exposure: forceful vomiting, watery diarrhea, cramping, and sometimes a low fever. The illness is miserable but short, usually fading in one to three days. Because so much fluid is lost, the real concern is dehydration, especially in the very young, the elderly, and anyone already frail. There is no medicine that kills the virus; the body clears it. The work is to keep fluids up, rest the stomach, and stop the spread with thorough handwashing, since alcohol gels are less effective against this particular virus than soap and water.
Common signs
- Sudden vomiting
- Watery diarrhea

🍽️ Eating to help
Food is one of the gentlest medicines — small, steady changes help most.
Favor these
- Oral rehydration fluids and water in small sips
- Bland starches: rice, toast, plain crackers, bananas
- Clear vegetable broth
- Diluted fruit juice once the stomach settles
Go easy on
- Greasy, fried, or spicy foods
- Dairy for a day or two if it worsens diarrhea
- Sugary sodas and very sweet drinks
- Caffeine and alcohol, which worsen fluid loss
The aim is gentle replacement of fluids; many small sips beat a few large gulps, which can come right back up.
⚖️ Good to know
- Watch closely for dehydration in young children and older adults.
- Do not prepare food for others while sick and for two days after.
