Norovirus cases skyrocket across US, here's how to avoid the stomach bug

Cases of norovirus, also known as food poisoning or the stomach bug, have picked up steam across the U.S.

The number of suspected or confirmed outbreaks skyrocketed at the end of 2024, with more than 91 norovirus outbreaks reported by state health departments by the first week of December, according to data from the Centers for Disease Control and Prevention (CDC).

Norovirus typically shows up with an onset of uncomfortable symptoms, including nausea, vomiting, diarrhea and stomach pain. In some cases, it can cause fever, headache and body aches.

CASES OF NOROVIRUS OR STOMACH FLU CLIMB STEADILY ACROSS US: ‘THIS IS THE SEASON FOR IT’

Chad D. Neilsen, MPH, director of Infection Prevention and Control at Nemours Children’s Health in Florida, shared with Fox News Digital that norovirus is the leading cause of foodborne illnesses in the U.S., causing about 20 million cases each year.

Norovirus is responsible for about 109,000 hospitalizations and 900 deaths each year in the U.S., mostly affecting adults over 65 years old, according to the National Foundation for Infectious Diseases (NFID).

About one in 15 Americans will get norovirus annually, and one out of 160 children will be hospitalized.

Spread and symptoms

People of any age can be infected and can show symptoms within two days, Neilsen noted.

“Norovirus is extremely contagious, and is usually transmitted between people via close contact, but often via surfaces, utensils or foods that are contaminated with the virus,” the doctor warned.

“There is no treatment except to stay well-hydrated.”

Fox News senior medical contributor Dr. Marc Siegel also weighed in, telling Fox News Digital that norovirus spreads “easily through food and food handling.”

“It is wildly contagious and hard to defend against except by frequent handwashing, identifying symptoms early (vomiting, diarrhea, low-grade fever), and isolating yourself if sick,” he said.

“There is no treatment except to stay well-hydrated,” the doctor added. “[It] generally lasts around 3 days.”

Neilsen agreed that most people will recover from norovirus in one to three days without any treatment, but others could experience more severe symptoms like dehydration, which “could require medical attention.”

Symptoms of dehydration include decreased urination, dry mouth and throat, dizziness when standing, crying with few or no tears, and unusual sleepiness or fuzziness, according to the CDC.

If norovirus strikes, the agency recommends drinking plenty of liquids to prevent dehydration and to seek medical care if it becomes severe.

Prevention of norovirus

Steps to avoid norovirus are similar to preventing any other foodborne illness, Neilsen shared.

“Wash your hands, thoroughly cook your food at the recommended temperatures, properly clean and disinfect surfaces, and avoid contact with others if sick,” he advised.

The CDC also recommends washing fruits and vegetables thoroughly and washing laundry in hot water if possible.

The foods most commonly involved in norovirus outbreaks are leafy greens, fresh fruits and shellfish, according to the CDC. (iStock)

The doctor reiterated how cases in the U.S. have been rising since 2023, but there is no clear research into the reasons why.

Norovirus typically peaks between November and April, according to Neilsen, most likely due to “seasonality trends” that are similar to other contagious viruses thriving during this time, like the flu.

“The combination of indoor spaces, close contact and crowding is why norovirus thrives in environments like schools, daycares and cruise ships,” he said.

“Once an outbreak starts, it’s challenging to control it without public health and sanitation expertise.”

Norovirus can be difficult to kill, Neilsen noted. He recommends using bleach to clean contaminated surfaces.

 

Some people may still be contagious after recovery. Experts recommend proceeding with caution and continuing disinfection routines.

Woman’s painful reaction to wine leads to life-changing cancer discovery

NEWYou can now listen to Fox News articles!

One woman’s uncomfortable reaction to alcohol led to a grave discovery.

Hollie Thursby, 28, a mother of two from the U.K., told Kennedy News and Media that after giving birth to her second son, Jack, she began experiencing unusual symptoms.

At a checkup for her son, who was a couple of months old, Thursby mentioned that she was experiencing “unbearably itchy skin,” which is known to be a post-partum symptom. The doctor suggested it was due to changing hormones.

Thursby added that she occasionally drank a couple glasses of wine. Although she kept the drinking to a minimum, she described having “a lot of pain” down the side of her neck.

“Really quite painful and uncomfortable,” she said, according to the report.

The mother also reported feeling extremely exhausted, which she assumed was due to caring for her children throughout the day.

“I also felt like when I got to bed that someone was sitting on my chest,” she shared.

In July 2025, Thursby discovered a lump on the side of her neck that she described as “really quite big,” but wasn’t painful, Kennedy News and Media reported.

“It was hard, it didn’t move, but it was there,” she said. “When I turned my neck to the side, you could see it.”

Thursby reportedly began chemotherapy for Stage 2 Hodgkins lymphoma. (Kennedy News and Media)

Thursby’s symptoms turned out to be a form of blood cancer — Stage 2 Hodgkins lymphoma, which means it is in two or more lymph nodes, according to Cancer Research U.K.

Common symptoms include swelling of the lymph nodes, heavy sweating, weight loss, itching, persistent cough or shortness of breath, high temperatures, and pain in the stomach or lymph nodes after drinking alcohol.

“Pain when you drink alcohol is actually a known side effect of Hodgkin lymphoma,” she said, per the report. “It’s something about the acidity in the wine and not when you drink other alcohol.”

While alcohol-related pain in Hodgkins lymphoma patients has been “an accepted scientific consensus” since the 1950s, cases are rare, Healthline confirmed.

Thursby reportedly began chemotherapy in November, noting that the hardest part is not being able to care for her kids after losing her own mother to a blood disorder called myelodysplasia.

“I grew up without a mum, and it was horrendous. I can’t do that to the boys,” she told Kennedy News and Media. “We’re all devastated, but we all know now, and we’ve got a treatment plan, which is what we need.”

Red light therapy could boost brain health in certain groups, new research suggests

NEWYou can now listen to Fox News articles!

Red light therapy has been shown to reduce brain inflammation, protecting people who experience head trauma from long-term health consequences, a University of Utah study has shown.

Brain damage from repeated impact over the years is known to cause cognitive symptoms, ranging from memory issues to full-blown dementia, particularly affecting soldiers and athletes.

Chronic traumatic encephalopathy (CTE) is a progressive, degenerative brain disease linked to repeated head impacts rather than a single injury, according to Mayo Clinic.

More than 100 former NFL football players have been posthumously diagnosed with CTE, according to the new study, which was published in the Journal of Neurotrauma.

Other research has shown that military personnel in active combat suffer from similar issues, as do first responders and veterans.

The treatment was administered three times a week for 20 minutes using specialized headsets and intranasal devices designed to penetrate the skull. (iStock)

In the new study, the researchers recruited 26 current football players to understand more about the impact of red-light therapy on brain injuries.

The participants received either red light therapy delivered by a light-emitting headset and a device that clips into the nose, or a placebo treatment with an identical device that doesn’t produce light. Players self-administered the therapy three times a week, 20 minutes each time, for 16 weeks.

“My first reaction was, ‘There’s no way this can be real,’” said first author Hannah Lindsey, Ph.D., in the university press release. “That’s how striking it was.”

Specific wavelengths of light are believed to enter the brain and reduce molecules that trigger inflammation, potentially halting the path toward dementia and other cognitive conditions. (iStock)

Players using the placebo treatment experienced increased brain inflammation over the course of the season. Magnetic resonance imaging (MRI) scans taken at the end of the season showed significantly more signs of inflammation than at the beginning of the season, the study found.

For players who used red-light therapy during the season, their brain inflammation didn’t increase at all.

“When we first started this project, I was extremely skeptical,” said Elisabeth Wilde, Ph.D., the senior author on the study. “But we’ve seen consistent results across multiple of our studies, so it’s starting to be quite compelling.”

Study limitations

The study was conducted using a small sample size, which led to different levels of inflammation in the treatment and control groups, the researchers acknowledged.

Future large randomized clinical trials will be “crucial to back up the results” in larger populations, they noted.

“We’ve been trying to figure out how to make sports safer, so that our kids, friends and family can participate in sports safely for the long term while they’re involved in activities that give them happiness and joy,” Carrie Esopenko, Ph.D., second author of the study, said in the release.

“And this really feels like part of the hope for protecting the brain that we’ve been searching for.”

Deadly cancer risk spikes with certain level of alcohol consumption, study finds

NEWYou can now listen to Fox News articles!

Drinking heavily and consistently over an adult’s lifetime could lead to a higher risk of colorectal cancer, according to a study published in the journal Cancer by the American Cancer Society (ACS).

The study analyzed 20 years of data from more than 88,000 U.S. adults to determine how long-term drinking impacted the risk of developing colorectal cancer (CRC) or precancerous colorectal adenomas (polyps).

The participants reported their average weekly intake of beer, wine and liquor intake during four age periods 18 to 24, 25 to 39, 40 to 54,  and 55 and older.

“Heavy drinkers” were identified as having more than 14 drinks per week and “moderate drinkers” had between seven and 14 drinks per week.

The observational research revealed that consistent heavy drinking over adulthood was linked to a higher risk of colorectal cancer, especially rectal cancer.

Researchers found a major association between colorectal cancer diagnosis and heavy lifetime drinking. (iStock)

Heavy lifetime drinking was associated with a 25% higher overall CRC risk and nearly double the risk of rectal cancer. Moderate lifetime drinking had a lower overall CRC risk.

Compared to light drinkers, the consistently heavy drinkers had about a 91% higher risk of CRC.

For colorectal adenomas (precancerous polyps), higher current lifetime drinking did not show a strong pattern, although former drinkers showed a significantly lower risk of non-advanced adenoma compared to current light drinkers.

Out of the 88,092 participants, 1,679 were diagnosed with colorectal cancer.

The authors noted that the research was limited, as it was observational and not based on a clinical trial. It also hinged on self-reported alcohol use.

The findings suggest that consistently heavy alcohol intake and higher average lifetime consumption “may increase CRC risk, whereas cessation may lower adenoma risk,” the researchers stated. Associations “may differ by tumor site,” they added.

The link between drinking alcohol and cancer is not a new discovery, according to health experts.

In a recent episode of the podcast “The Dr. Mark Hyman Show,” Dr. Mark Hyman, chief medical officer of Function Health in California, detailed how even moderate drinking can impact “nearly every organ system in the body,” due to metabolic stress, inflammation, impaired detoxification and its effect on hormones.

“Over months to a year, we see sustained improvements in blood pressure, liver function and inflammation,” she said. “Those changes directly affect long-term heart disease and stroke risk.”

Chiang added, “Reducing or eliminating alcohol lowers the risk of several cancers, including breast and colorectal, over time.”
