Each winter we see a drop in temperatures and a rise in norovirus. Here’s what you need to know about the virus that’s also known as “winter vomiting disease.”

Norovirus cases are increasing as winter approaches, with virus concentrations in wastewater indicating widespread activity across the country. The virus, known for causing nausea, vomiting, diarrhea, and stomach pain, typically resolves within 72 hours.

Health officials recommend staying home for at least two days after symptoms subside to prevent further spread. Proper handwashing with soap for 20 seconds is advised, as hand sanitizers do not effectively stop norovirus transmission.

It isn't just the temperature that changes with the seasons, viruses do too. As we head into winter, norovirus is on the rise again. Here's what you need to know about the winter vomiting disease. Norovirus is tracked by analyzing virus concentrations in wastewater, and the numbers are currently high across the country. Norovirus can cause nausea, vomiting, diarrhea, and stomach pain. The symptoms typically clear within 72 hours. If you're sick, you should stay home for at least two days after symptoms subside. If you want to avoid gastrointestinal misery though, start by washing your hands with soap for 20 seconds. Hand sanitizers aren't effective at stopping norovirus.
