Norovirus cases are spiking across the United States this December, with a record number of outbreaks reported by the Centers for Disease Control and Prevention (CDC). This surge in the highly contagious stomach bug comes just as Americans plan for New Year’s gatherings, creating a significant public health concern. The new data shows a sharp increase in infections, surpassing all previous December records since tracking began in 2012.
A Record Breaking December for Norovirus Outbreaks
The latest figures from the CDC paint a clear picture of a widespread problem. The week of December 5 alone saw 91 reported norovirus outbreaks, a substantial increase from the 69 outbreaks reported just one week prior. This number has officially broken the previous December record of 65 outbreaks for a single week.
While the CDC has not released the total number of individual cases or specified which states are most affected, the national trend is undeniable. This surge highlights the virus’s aggressive spread during its peak season, which typically runs from November to April.
Norovirus is a major cause of foodborne illness in the country, accounting for 58% of all cases each year. The virus leads to about 2,500 outbreaks annually, often in crowded places like schools and nursing homes.
Why the Timing of this Surge is a Major Concern
The timing of this outbreak could not be worse, as it coincides with the holiday season when people gather indoors in large groups. This creates an ideal environment for the virus to spread rapidly. Norovirus is extremely contagious, and it only takes a very small amount of viral particles to make someone sick.
Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, explained its reputation. “Norovirus is sometimes called the ‘winter vomiting disease’ or ‘the cruise ship virus’ because it spreads so easily in close quarters,” he said.
The symptoms, including vomiting, diarrhea, and nausea, can appear very suddenly. These symptoms can lead to severe dehydration, posing a serious risk to young children, the elderly, and people with weakened immune systems.
How this Contagious Virus Spreads
Norovirus is known for being incredibly efficient at infecting people. Its ability to survive on surfaces for days makes it very difficult to control, especially in shared spaces. Understanding how it spreads is key to preventing infection.
The virus primarily spreads through several common routes:
- Direct person-to-person contact with someone who is infected.
- Touching contaminated surfaces or objects, like doorknobs or utensils, and then touching your mouth.
- Consuming food or water that has been prepared by an infected person.
Because of its persistence, public health officials are stressing the importance of thorough cleaning and hygiene to break the chain of transmission.
Steps you can Take to Protect your Family
Public health experts urge everyone to be extra cautious. “It doesn’t take a lot to get people pretty sick. That’s the main reason it’s so infectious,” stated Dr. Georges Benjamin of the American Public Health Association. He and other experts recommend simple but effective preventive measures.
The most important step is frequent and proper handwashing with soap and water for at least 20 seconds. This is more effective than hand sanitizers against norovirus. Additionally, regularly cleaning and disinfecting high-touch surfaces in your home, like countertops and bathroom fixtures, is crucial.
If you or someone in your household starts to feel sick, it is vital to stay home and avoid preparing food for others to prevent further spread. Refraining from sharing food, drinks, or utensils can also help protect those around you.
