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.”
IS IT SAFE TO EAT EGGS AMID BIRD FLU OUTBREAKS?
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.

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.
ALZHEIMER’S SCIENTISTS FIND KEY TO HALTING BRAIN DECLINE BEFORE SYMPTOMS
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.
ALZHEIMER’S RISK COULD RISE WITH COMMON CONDITION AFFECTING MILLIONS, STUDY FINDS
Previous studies have shown that red light, if powerful enough, can penetrate the skull and reach the brain, where it may reduce inflammation-related molecules.

“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.
While the placebo group showed increased brain inflammation during the football season, those receiving red light therapy showed no increase in inflammatory markers. (iStock)
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.”

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.
DOCTOR REVEALS WHAT 30 DAYS WITHOUT ALCOHOL DOES TO THE BRAIN AND BODY AMID DRY JANUARY
“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.

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.
EXPERTS REVEAL WHAT ‘REASONABLE’ DRINKING LOOKS LIKE – AND WHO SHOULD AVOID ALCOHOL
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.

“Bottom line, alcohol taxes every major system in your body, especially your liver, your brain, your gut, your hormones,” he warned.
Reducing or eliminating alcohol can lower the risk of several cancers, according to medical experts. (Getty Images)
In a previous interview with Fox News Digital, Dr. Pinchieh Chiang, a clinician at Circle Medical in San Francisco, shared that taking a break from drinking alcohol for longer periods of time can “reshape health more profoundly.”

“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.”

A mysterious hum is reportedly plaguing the residents of Cincinnati, keeping people up at night and even disturbing them psychologically.
Residents of the Northside, Clifton and Camp Washington neighborhoods have been reporting the disturbances since December. The noises are said to be louder and more noticeable at night.
“We were hearing this siren-like quality noise — whirring, oscillating, going up and down,” said Clifton resident Shaun Herold, who contacted local news outlet WKRC about the noises.

“My son came up to me and said, ‘Dad, the tornado sirens are going off,’” Herold said. “Usually, it starts at about 10 p.m. It can go till 3 a.m., 4 a.m. But it’s quite unpredictable.”
“It kind of stresses me out ’cause I don’t know what it is. It’s kind of scary,” added his son, Elijah Herold.

Herold said he spent one entire night tracking how many times he heard the noise going on and off. The duration of the noises can vary from a few seconds to several minutes.
“I feel like it’s definitely like a foreign sound,” Northside’s Brendan Marcum told the news outlet. “Some nights it would be a little louder, some nights it would be a little quieter.”
“It kind of stresses me out because I don’t know what it is, and it’s kind of scary,” added another resident.

Hundreds of Cincinnati residents have shared their theories about potential sources of the sound on social media, ranging from biblical to supernatural.
On Reddit, other users blamed the recycling plant. “My favorite theory is River Metals Recycling,” one person wrote, claiming that the plant moved neighborhoods when the original location “wouldn’t put up with the noise from its metal shredder any longer.”
Residents have described the sound as a siren-like, oscillating whirring that can last from seconds to several minutes. (iStock)
Others suspect the noise is coming from a failing turbocharger on a diesel train engine at the nearby CSX Queensgate, a major freight rail yard in Cincinnati.
While the yard routinely generates loud, mechanical sounds, residents say they’ve never heard anything like this before.

WKRC reported that an anonymous source sent recordings of the locomotive, claiming it to be the source of the sound. However, a spokesperson for CSX told the news station that he “has not heard a noise like that on our property” and suggested it could be coming from another location.

He added that any equipment requiring maintenance is “handled through established operating and mechanical protocols.”
According to a source, rail crews have reported the engine for excessive noise and believe it will be repaired. (iStock)
“We just hope to get to the bottom of it, figure out what it is, and if it’s, you know, a temporary thing or not,” Herold told the news outlet. “And hopefully the community can rally if it’s not temporary, because it’s really impacting us.”
