During the winter months, many people try to find ways to stay entertained but out of the elements. One activity many turn to is going to see a movie. There are many movie theaters such as AMC Northgate 14 advertising new films for us to enjoy while eating popcorn in the comfortable, warm seats of the theater. However, public spaces, including movies, can also increase your risk of catching illnesses like norovirus, commonly known as the stomach flu. In this guide, you’ll learn about the new variant of norovirus, how it spreads, symptoms to watch for, at-home treatment, and the best strategies for prevention. 

Norovirus is one of the most contagious viruses, responsible for causing acute gastroenteritis, which leads to nausea, vomiting, diarrhea, and stomach cramps. Norovirus spreads year-round, but most outbreaks occur between November and April. It’s also the most common cause of food poisoning. It spreads rapidly in most enclosed spaces. Along with the flu, norovirus is expected to keep spiking in the coming weeks. Here’s what to expect this winter, which norovirus symptoms to look out for, and how to protect yourself.

The New Norovirus Variant: GII.17 

This season has seen an early surge in norovirus cases, driven by a newer variant called GII.17. Previously, most outbreaks were caused by the GII.4 strain. This new variant now accounts for a significant percentage of cases in the U.S., and while it’s unclear whether it’s more contagious than older strains, more people may be susceptible due to limited prior exposure. 

Understanding this new variant helps explain why norovirus outbreaks are more common in winter and why awareness of transmission and prevention is critical. 

How Norovirus Spreads  

Norovirus is highly contagious and spreads through several pathways: 

• Direct Contact: Shaking hands, caring for an infected person, or sharing food and drinks can spread the virus. Even a tiny amount of the virus can cause infection. 
• Contaminated Food or Water: Consuming foods prepared by someone with norovirus or drinking water that is contaminated can lead to infection.  
• Touching Contaminated Surfaces: Norovirus can survive on surfaces like doorknobs, gym equipment, and countertops for up to two weeks. Touching these surfaces and then touching your mouth, nose, or eyes can introduce the virus into your system. 

A person with norovirus is most contagious from symptom onset until a few days after recovery, but viral particles can be shed in stool for up to two weeks. Outbreaks often occur in homes, schools, daycare centers, nursing homes, restaurants, gyms, and cruise ships. The virus is also resistant to many disinfectants, hand sanitizers, and extreme temperatures, making it difficult to eliminate without proper sanitation. 

Recognizing Norovirus Symptoms 

Symptoms typically appear 12–48 hours after exposure and last 1–3 days, though they can be intense.  

Common signs include: 

• Sudden nausea and vomiting 
• Watery diarrhea 
• Stomach cramps 

Less common symptoms: 

• Low-grade fever and chills 
• Muscle aches and fatigue 
• Headache 

For most people, norovirus is uncomfortable but manageable.  However, dehydration is a concern; especially for young children under 5, older adults over 85, and people with weakened immune systems. Seek medical care if symptoms persist after several days, if there is blood in vomit or stool, or signs of dehydration appear such as dark urine, dizziness, or confusion. 

If symptoms are still present after a few days, worsen, or you have signs of dehydration; contact AFC and book an appointment for expert treatment and care. 

At-Home Treatment for Norovirus 

Since norovirus is a viral infection, antibiotics will not help. Focus on symptom relief and hydration such as: 

• Hydration: Drink water, electrolyte solutions, or clear broths as tolerated. Avoid alcohol and caffeine. 
• Rest: Allow your body time to fight the virus. Get plenty of sleep and take it easy.  
• Bland Diet: The BRAT diet is your best bet. Stick to gentle foods like toast, rice, bananas, and applesauce until your stomach settles. Avoid spicy foods or dairy.  
• Over-the-Counter Medications: Anti-nausea or anti-diarrheal medications may help with symptoms but will not cure norovirus. However, these should only be taken under guidance from an AFC medical provider. 

Preventing the Spread of Norovirus 

Taking preventative measures is necessary to protect yourself and others from the spread of the highly infectious norovirus: 

• Wash Hands Thoroughly: Use soap and water for at least 20 seconds after using the restroom, preparing food, or caring for someone who is ill. Hand sanitizer is not effective against norovirus. 
• Disinfect Surfaces: Use a bleach-based cleaner, such as Lysol®, on frequently touched surfaces. Alcohol-based cleaners do not eliminate the virus. 
• Practice Safe Food Handling: Wash fruits and vegetables, cook shellfish to safe temperatures, and avoid preparing food when sick. 
• Avoid Direct Contact with Infected People: Use social distancing guidelines and masks if necessary as well as the above recommendations to keep yourself healthy. 
• Stay Home if Sick: Do not return to work, school, or public spaces until at least 48 hours after symptoms subside. 

Does Hand Sanitizer Kill Norovirus? 

Norovirus is very hard to kill. Alcohol-based sanitizers and cleaners are not effective against norovirus because the virus particles have a firm outer shell that alcohol cannot break down. 

Instead, the virus needs to be physically washed off the hands. Soap and water help neutralize the virus and rinse the virus down the drain.  

Bleach-based cleaners are effective at killing norovirus on surfaces and objects.
