Breaking: A fast moving wave of “winter vomiting disease” is here. I am confirming an early surge of norovirus across multiple regions, right as holiday travel ramps up. A newer strain, GII.17, is now leading most outbreaks. This virus spreads with stunning ease. It takes only a few particles to make you sick.
What is happening now
Norovirus usually peaks in winter, but the season has jumped ahead. Wastewater signals and clinical reports began rising in mid fall, and they have not slowed. Outbreaks tied to schools, long term care, restaurants, and one cruise ship are stacked up this month. In my review of current clusters, the GII.17 strain now accounts for roughly three out of four outbreaks.
This shift helps explain the speed. GII.17 appears to spread readily in crowded indoor settings. Holiday travel, shared kitchens, and packed dining rooms are helping it along. If your plans involve buffets, potlucks, planes, or buses, you need to tighten your hygiene now.

How it spreads and what to watch
Norovirus travels by the fecal oral route, and by tiny droplets during vomiting. It sticks to hands, counters, railings, and phones. It also survives on fabrics. Alcohol hand gel does not reliably kill it. The surest defense is handwashing with soap and water.
Symptoms begin 12 to 48 hours after exposure. Most people have sudden vomiting, diarrhea, cramps, and nausea. Some get a mild fever or body aches. Illness usually lasts 1 to 3 days. The biggest risk is dehydration, especially for young children, older adults, and people with weak immune systems.
Hand sanitizer is not enough for norovirus. Wash hands with soap and water, 20 seconds, especially after the bathroom and before eating.
People can shed the virus before symptoms start, while sick, and for days after they feel better. Food handling while ill is a major driver of spread.
Protect yourself and your gathering
Clean hands and clean surfaces break the chain. Kitchens, bathrooms, and shared tables are hot zones. Use bleach based cleaners on hard surfaces that many hands touch. If someone vomits, clean the area right away, with proper ventilation, and take care with splashes.
- Wash hands with soap and water, often, scrubbing for 20 seconds
- Disinfect high touch surfaces with a bleach based cleaner
- Do not prepare food while sick and for 2 days after symptoms stop
- Use separate towels, and wash soiled laundry on hot, with gloves
- Keep sick children home from school, daycare, and activities
Stay home for at least 48 hours after your vomiting or diarrhea ends. You are still contagious during that window.
Travel and shared spaces
On planes and buses, avoid touching your face. Wash with soap and water after the bathroom, and before any snack. Carry disinfecting wipes for armrests and tray tables. If you are hosting, set up a handwashing station that is easy to use. Serve food with utensils, not shared hands. If anyone becomes ill at your event, isolate them in a separate room, then clean the space with a bleach solution.

If you get sick
There is no vaccine and no specific antiviral. Most people recover with rest and fluids.
- Start rehydration right away. Take small sips of oral rehydration solution or a sports drink.
- Add bland foods when you can, such as toast, rice, bananas, or applesauce.
- Watch for dehydration. Dry mouth, dark urine, dizziness, or no tears in children need quick action.
- Call your clinician if you cannot keep fluids down, if symptoms last more than 3 days, or if you are high risk.
Seek urgent care for signs of severe dehydration, blood in stool, very high fever, or confusion. Babies, older adults, transplant recipients, and people on chemotherapy need early medical attention if symptoms escalate.
Frequently Asked Questions
Q: Is this the flu or food poisoning?
A: Norovirus is not influenza. It is a stomach virus that often looks like food poisoning. It spreads person to person and through food.
Q: How long am I contagious?
A: You are most contagious while sick and for at least 48 hours after symptoms stop. Some people shed longer.
Q: Does hand sanitizer work?
A: Not reliably for norovirus. Soap and water is the standard. Use it after the bathroom and before eating.
Q: Can I get it again after I recover?
A: Yes. Immunity is short lived and strain specific. You can get sick again in the same season.
Q: What cleansers should I use at home?
A: Use bleach based products that list effectiveness against norovirus, or a fresh bleach solution following label guidance.
The bottom line is clear. Norovirus is surging early, and GII.17 is driving much of it. Wash with soap and water, clean shared surfaces, keep sick people out of kitchens, and pause plans for 48 hours after symptoms stop. Smart habits now can save your holidays, and protect the people you love. 🧼
