Protect your health: Norovirus surges amongst Americans – are you at risk?
- Replies 0
As the cold winter weather settles in and we gather for warmth and shared stories, an unwelcome guest is making its rounds across the US: Norovirus. This highly contagious virus, known as the "winter vomiting bug," tends to strike when we're huddling indoors, escaping the chill outside.
Now, it’s surging across the nation, affecting one in four Americans who seek medical help for stomach issues. Its rapid spread is concerning, especially as we enter the colder months when it thrives in close-contact settings.
Here at The GrayVine, we understand how crucial it is to stay informed about potential health risks, particularly for our community of vibrant seniors who may be more vulnerable to the virus's effects.
Let’s take a closer look at what’s happening with norovirus, why it's spreading at such alarming rates, and most importantly, how you can protect yourself and your loved ones during this challenging season.
Recent data paints a concerning picture: norovirus infections have surged dramatically, with over 820 confirmed cases reported in just one week.
However, this is likely just the tip of the iceberg. Many people don’t seek testing, so the true number of cases is likely much higher.
Compared to last year, norovirus cases have doubled. The Centers for Disease Control and Prevention (CDC) reports the highest surge since pre-pandemic times.
Test positivity rates, which were as low as 0.6% in November 2020, have now jumped to 28% in the first week of January 2025, according to the National Respiratory and Enteric Virus Surveillance System (NREVSS).
Norovirus is known for causing acute gastroenteritis, which includes symptoms like diarrhea, vomiting, nausea, and stomach pain. It’s highly contagious, spreading through contact with infected people, contaminated food or water, and touched surfaces.
For seniors, the virus is especially dangerous and can lead to serious complications. In fact, approximately 900 deaths occur each year due to norovirus in adults over 65.
The virus thrives in the winter months when people are more likely to gather indoors, making it easier to spread.
Symptoms typically appear within 12 to 48 hours after exposure, and while most people recover within a few days, the risk of severe dehydration is a significant concern, particularly for older adults.
The CDC has noted regional variations in norovirus rates across the country. Region 2, which includes states like Missouri, Illinois, and Michigan, has reported the highest positivity rate, with nearly 30% of tests coming back positive.
In contrast, Region 3, which includes states like Texas and Florida, had a lower positivity rate of 14%.
Experts are currently investigating whether a new strain of norovirus might be driving this surge in cases.
While genetic tests have not yet confirmed significant changes in the virus, the possibility of a new strain—one that people have little immunity to—remains a concern.
To safeguard against norovirus, here are some important steps to consider:
1. Hand Hygiene: Wash your hands thoroughly with soap and water for at least 20 seconds, especially after using the restroom and before eating or preparing food.
2. Food Safety: Wash fruits and vegetables before eating, cook seafood to at least 145°F, and avoid sharing utensils with others.
3. Surface Sanitization: Regularly clean and disinfect surfaces like countertops and other frequently touched areas.
4. Social Precautions: Keep a safe distance from people who are sick and consider wearing a mask in crowded indoor spaces, especially during peak norovirus season.
5. Stay Informed: Keep track of local health advisories and be aware of any norovirus outbreaks in your area.
For our GrayVine community, staying vigilant against norovirus is especially important. As we age, our immune systems naturally weaken, making us more vulnerable to infections like norovirus. By taking simple, proactive steps to prevent illness, we can enjoy the winter season with greater peace of mind.
