ATLANTA (AP) — U.S. health officials report norovirus outbreaks have reached their highest December levels in more than a decade, with 91 suspected or confirmed outbreaks recorded in the first week of the month.
The surge in cases of the highly contagious “winter vomiting bug” comes earlier than usual, as the virus typically peaks between November and April, with February historically being the most active month.
“We’re seeing an unprecedented early spike in norovirus cases, likely due to increased social gatherings post-pandemic,” said Dr. James Carter, infectious disease specialist at the CDC. “This trend, combined with rising flu, RSV, and COVID-19 cases, raises concerns about a potential ‘quad-demic.'”
Norovirus, despite its “stomach flu” nickname, is unrelated to influenza. The virus spreads through contact with infected fecal particles, often via contaminated food, surfaces, or close contact with infected individuals.
Symptoms include:
- Vomiting and nausea
- Diarrhea and stomach pain
- Possible fever and headaches
- Body aches
Most patients recover within three days, though proper hydration is crucial to prevent complications.
Health officials recommend several preventive measures:
- Thorough hand washing with soap and warm water for at least 20 seconds
- Careful food preparation and avoiding shared dishes
- Hot water laundering of contaminated items
- Self-isolation for two days after symptoms resolve
Currently, no vaccine exists for norovirus, though Moderna has begun clinical trials for a potential preventive treatment.
“While we don’t have a vaccine yet, basic hygiene measures remain our best defense,” Carter said. “People should be especially vigilant during holiday gatherings and winter social events.”
