Norovirus is spreading earlier again this year, wastewater data shows
Last year's outbreaks were the largest in a decade, fueled by an emerging variant of the highly contagious, hard-to-kill virus. What will this year look like?
www.nbcnews.comHere are the latest general updates on norovirus:
-
What it is: Norovirus is a highly contagious stomach illness that causes sudden vomiting and diarrhea. Most people recover within 1–3 days, but dehydration can be a risk for young children, older adults, and those with weakened immune systems.[8]
-
Current trend: There has been a renewed surge in norovirus activity in parts of the U.S., with wastewater data and health reports signaling rising case counts and earlier-than-usual upticks in some regions. Experts emphasize that activity can fluctuate week to week and may vary by locality.[1][2]
-
Symptoms and transmission: Common symptoms include vomiting, diarrhea, stomach cramps, fever, and body aches. It’s highly transmissible through contaminated food, surfaces, and close contact; many people can shed virus even after symptoms resolve. Handwashing with soap and water (not alcohol-based sanitizers) and proper surface disinfection help reduce spread.[2][8]

Preventive tips for you in Buffalo area:
- Practice strict hand hygiene: wash hands with soap and water for at least 20 seconds, especially after using the restroom, before eating, and after changing diapers.[8]
- Disinfect contaminated surfaces with a chlorine-based household cleaner or a bleach solution (1 part bleach to 50 parts water for hard surfaces).[8]
- Stay home from work or school for at least 24–48 hours after symptoms stop to avoid spreading the virus. Hydration is key during illness; seek medical care if you’re unable to keep fluids down or you’re in a high-risk group.[2][8]
-
When to seek care: If you’re unable to keep fluids down, show signs of dehydration (very dark urine, dry mouth, dizziness), have a fever lasting more than a couple of days, or you’re in a high-risk group (infants, elderly, pregnant individuals, or those with chronic conditions), contact a healthcare provider. There is no approved vaccine yet, though vaccines are in development stages.[2][8]
Illustrative quick takeaway: Norovirus tends to spike in waves and can vary by region; standard hygiene and careful cleaning practices remain the best defense while outbreaks are ongoing.[1][8]
