Norovirus is on the Rise in the US: Here’s What You Need to Know to Stay Safe
Winter isn’t just the season for cozy sweaters and hot cocoa—it’s also prime time for norovirus, the highly contagious bug that’s currently making its rounds across the United States. But here’s where it gets controversial: while many assume it’s just another stomach flu, norovirus is actually the most common cause of vomiting and diarrhea in the U.S., according to Dr. Brintha Vasagar, a family physician in Wisconsin. And this is the part most people miss: it’s not just spread through the usual coughs and sneezes like the flu or COVID-19—it’s far more resilient and sneaky.
Norovirus typically peaks between November and April, and while cases are slightly lower than last year at this time, experts like Dr. Camile Gooden, an internal medicine physician at NYU Langone Hospital—Suffolk, warn of a recent surge due to a new strain. So, what makes this virus so tricky? It spreads through vomit and fecal particles, often lingering on surfaces, hands, or even in the air. Imagine this: someone with norovirus uses a towel after washing their hands poorly, and the next person who uses that towel could unknowingly pick up the virus. Creepy, right?
But here’s the kicker: hand sanitizer doesn’t kill norovirus. That’s right—your go-to sanitizer is practically useless against this stubborn virus. Instead, proper handwashing with soap and water is your best defense. Dr. Ross Newman, a pediatrician and social media medical communicator, puts it bluntly: ‘It’s not like you’re licking other people’s poop, but contaminated particles can end up anywhere—hands, surfaces, even your food.’
Speaking of food, norovirus can spread through contaminated produce or shellfish, too. Dr. Gooden advises washing fruits and vegetables thoroughly with water (no fancy soaps needed) and fully cooking shellfish to kill the virus. And if someone in your home is sick? Disinfect surfaces with bleach-based cleaners and wash linens frequently—norovirus can survive on fabrics, toys, and more.
If you do get sick, stay home, hydrate, and watch for severe symptoms like dehydration, which can be dangerous. Dr. Newman warns, ‘The vomiting might stop after 24 to 48 hours, but diarrhea can last up to two weeks.’ And here’s a thought-provoking question: Are we doing enough to prevent outbreaks in crowded spaces like daycares, nursing homes, and cruise ships, where norovirus thrives?
So, what’s your take? Are we underestimating the threat of norovirus, or is it just another winter bug we’ve learned to live with? Let us know in the comments!
