Norovirus Spreads Earlier Than Expected This Year, Wastewater Data Shows
The highly contagious norovirus, also known as the "winter vomiting disease," has been on the rise across the country since mid-October, with a significant spike in wastewater concentrations nationwide. According to data from WastewaterSCAN, an academic program through Stanford University in partnership with Emory University, norovirus cases have increased by 69% since October.
The Centers for Disease Control and Prevention (CDC) has reported 235 outbreaks of norovirus between August and November 2024, compared to 153 during the same period this year. While it's unclear how severe the current outbreak will be, experts warn that norovirus symptoms such as diarrhea and vomiting may require medical attention for vulnerable populations.
A closer look at the data suggests that norovirus variant GII.17 may have become more contagious, leading to an earlier start to the season. Researchers believe a combination of factors contributed to this shift, including changes in the virus itself and population susceptibility.
The good news is that experts expect increased immunity from last year's outbreaks, which could lead to fewer cases overall. However, with the norovirus season typically spanning from November to April, there's still plenty of time for the virus to spread.
As the winter months approach, it's essential to take preventive measures against norovirus. Washing hands vigorously with soap, cleaning infected areas with diluted bleach, and cooking shellfish properly can all help reduce the risk of infection.
While a specific treatment for norovirus isn't available, rehydration is key to replacing lost fluids. Researchers are working on developing a vaccine, with a Phase 3 Moderna trial currently underway.
With its high transmissibility and stability in the environment, norovirus is indeed a formidable pathogen. By understanding the risks and taking proactive steps, we can reduce the spread of this highly contagious virus.

, I remember when we didn't even know about this stuff! Now we gotta worry 'bout norovirus all winter long? It's like the flu, but worse... you know what I mean? 
Always washing hands, always cleaning up after kids (or whatever). My grandma used to say "if you've got a runny nose, don't go out there!" 
That was her way of saying wash your hands. I'm not sure about this vaccine thing though, sounds like it's still in the works... 
, more norovirus? I mean, isn't it already bad enough that we have to deal with these awful viruses in the first place? And now they're telling us it's gonna be worse this year? 
Come on! The fact that it's spreading earlier than expected is just crazy. 69% increase since October? That's insane! What's going on, right? Is it something we can do anything about? I don't think so...
gotta stay vigilant about hand hygiene & cooking food properly 
. As for me, I think it's just common sense to take precautions against norovirus during the winter months 
.
. Rehydration is key in treating norovirus symptoms, but it's not a cure-all 
. With increased immunity from last year's outbreaks, I hope we'll see fewer cases overall 
. The development of a vaccine is a promising area of research 
.
. By staying informed and taking proactive steps, we can reduce the spread of this highly contagious virus and protect ourselves and our loved ones 
.
! It seems like every year it's the same thing - norovirus is back and spreading fast 
. In the meantime, I'm all about handwashing ( lots and lots of soap 
. Maybe if we all just take a few precautions, we can minimize the spread of this nasty virus 
69% increase in cases since october? that's crazy! i remember last year being super sick and thought it was just me being paranoid 
anyway, it sounds like the norovirus variant is more contagious now which explains why its starting earlier than usual. anyone know if there are any good treatments or cures yet? rehydration is key but idk how hard that is to do when your body's literally shutting down 
I guess we should've seen it coming, considering how easily it spreads and the fact that population susceptibility has changed over time.
anyway we gotta take care of ourselves wash our hands all the time and be extra careful with food especially when cooking for others 
And what's the deal with this new variant GII.17 being more contagious? That sounds super scary! 
At least some good news is that people got a taste of it last year and might be immune now, but what about those who aren't? We need to get our act together and figure out how to keep these outbreaks under control before they take off completely! 
And don't even get me started on the 'good news' about increased immunity... yeah right, like that's gonna save us from all the snot-nosed kids at school and their mamas 
. Can't we just have one winter without a major outbreak for once? 
.
. Cook 'em proper or not at all!
