Preventing the Norovirus: A Guide to Staying Healthy this Winter
The Norovirus, often dubbed the "winter vomiting bug," is a highly contagious virus that causes gastroenteritis. You may know a friend, coworker, family member or child who has had it. It's notorious for causing outbreaks in places like schools, work, medical facilities, and even cruise ships. Unlike the common cold, it can stop us in our tracks, unable to attend work, school, and other activities. But don’t worry—there are simple ways to protect yourself and others.
It’s not your imagination, more people really do have the Norovirus this year. As of January 2025, norovirus cases are rising in the U.S. The CDC reports over 1,000 outbreaks from August 2024 to January 15, 2025, more than double the previous year's count. In New York City alone, cases have increased by 159% compared to the same period last year.
How the Norovirus Spreads
The Norovirus is very contagious. It spreads like wildfire through:
Contaminated food or water: Think of that potluck where food wasn’t kept at the right temperature.
Touching contaminated surfaces: And then touching your mouth without washing your hands.
Close contact with an infected person: Even tiny particles from vomit can spread the virus (yes, it’s as gross as it sounds)
Prevention: Your Best Defense
Wash Your Hands: Wash your hands like a surgeon. What I mean by that is scrub your hands really good including the nails, palms and up the wrists. Use soap and water for at least 20 seconds. Alcohol-based sanitizers are less effective against norovirus but if that is all you have then use that.
Disinfect Surfaces: Norovirus can survive on surfaces for days. Use a bleach-based cleaner to disinfect frequently touched areas.
Stay Home if Sick: If you’re experiencing symptoms, it’s crucial to stay home to avoid spreading the virus. Your coworkers, friends, and classmates will appreciate that.
Avoid touching your nose and mouth with your hands: Grab a clean tissue if you need to itch or blow your nose. Keep your hands off your face so those nasty germs stay away. Viruses often enter the body by your mouth or nose.
Launder contaminated clothing and linens. Use hot water and detergent, and wear gloves if you’re handling items that are soiled.
Recognizing the Symptoms
Norovirus isn't shy. When it hits, you'll know it. The symptoms usually show up 12 to 48 hours after exposure and can last 1 to 3 miserable days. Here's what to watch for:
Nausea and vomiting: The kind that comes on fast and furious.
Diarrhea: Often watery and frequent.
Stomach cramps: Your belly may feel like it's doing somersaults..
Low-grade fever, chills, headache, and body aches: Think of it as an unwanted bonus round.
What to Do If You Catch Norovirus
If norovirus finds you despite your best efforts:
Stay hydrated. Sip on water, oral rehydration solutions, or clear broths.
Rest. Your body needs energy to fight the virus.
Monitor for dehydration. Seek medical help if you’re unable to keep fluids down, feel dizzy, or show signs of severe dehydration.
Final Thoughts
Norovirus might be a tough opponent, but with good hygiene, smart food practices, and a little vigilance, you can reduce your risk. If it does catch you off guard, remember stay hydrated, rest up, and keep your germs to yourself. You've got this!
