Norovirus, often called the “stomach flu” or “winter vomiting illness,” is currently circulating in California and across the United States. Health experts say proper cleaning and disinfecting can slow its spread. These precautions matter because norovirus is extremely contagious and there is no specific treatment for it, according to the Centers for Disease Control and Prevention.

Between August 1 and November 13, health officials recorded 153 norovirus outbreaks across 14 states. The CDC defines an outbreak as two or more similar illnesses linked to suspected or lab-confirmed norovirus cases. Although California is not among the states reporting outbreaks, CDC data shows a noticeable rise in positive norovirus tests throughout November across the western US.

What Is Norovirus?

Norovirus is described as a “highly contagious” virus that causes vomiting, diarrhea, and stomach cramps, according to the California Department of Public Health. It leads to acute gastroenteritis, which means inflammation of the stomach or intestines, and affects people of all ages, the CDC said.

Despite its nickname, norovirus has nothing to do with influenza. The flu is caused by the influenza virus, not norovirus, the agency clarified.

Winter Vomiting Disease: How Does The Stomach Bug Spread?

Norovirus spreads easily from person to person, especially while someone is actively sick, according to the California Department of Public Health. Symptoms usually last one to three days, but a person can still spread the virus for up to two days after they start feeling better.

The virus is present in vomit and stool and can spray into the air or settle on nearby surfaces. It can survive for weeks on uncleaned items such as countertops, phones, and doorknobs, the department said.

“You can get sick after touching or caring for someone who is sick, or after touching or eating something that is contaminated,” the department noted.

Norovirus spreads quickly in crowded or enclosed settings, including schools, child care facilities, hospitals, nursing homes, jails, and cruise ships.

According to state and federal health officials, the most common ways people catch norovirus include:

• Touching, caring for, or sharing food with someone who has norovirus
• Eating or drinking contaminated food or beverages, including undercooked shellfish like oysters
• Touching a contaminated surface and then touching your mouth before washing your hands
• Sharing a toilet or bathroom with someone who is sick
• Swallowing contaminated water, including water from swimming pools or recreational areas
• Cleaning up vomit or diarrhea without protective gear, such as gloves or a face mask

Do You Need To Disinfect After Norovirus?

“If you or someone in your household has norovirus, it’s important to clean and disinfect areas where vomiting or diarrhea occurred,” the California Department of Public Health advised. Cleaning with soap and water removes germs, while disinfecting kills those that remain.

You can use commercial disinfectants, but it’s important to read the label and make sure norovirus is listed among the germs it targets. You can also check the Environmental Protection Agency’s registration number and confirm it appears on the EPA’s List G, which includes products proven effective against norovirus.

Another option is making a bleach solution at home. The US Department of Agriculture recommends mixing 5 to 25 tablespoons of household bleach with one gallon of water. This solution should be used only on hard or nonporous surfaces and applied with a spray bottle or disposable mop, sponge, or paper towel. Let it sit for about five minutes before wiping it away.

The USDA also advises paying close attention to frequently touched items such as doorknobs, handles, and remote controls. Many disinfectant wipes do not fully kill norovirus, the agency warned.

How To Disinfect After Norovirus?

The CDC recommends wearing rubber or disposable gloves while cleaning. Use paper towels to wipe the affected area completely, then place the towels in a plastic trash bag. The California Department of Public Health also suggests wearing a face mask.

After disinfecting, clean the area again with soap and water, the CDC said. Keep in mind that vomit can aerosolize the virus, meaning surfaces several feet away may also be contaminated, according to the USDA.

Once you’re done, throw away the gloves and mask, then take out the trash, the California Department of Public Health advised.

The use of nicotine pouches is rising sharply across the UK, especially among young adults, recent research suggests. These small pouches sit between the lip and gum and release nicotine gradually into the body. Available in many flavours, they often include sweeteners and plant-based fibres. But are they truly a better option than smoking, or could nicotine pouches still pose health risks? We take a closer look below.

What Are Nicotine Pouches?

Nicotine pouches are small, tobacco-free sachets that contain nicotine powder along with flavourings and fillers. They are placed between the lip and gum, similar to snus, allowing nicotine to be absorbed without smoke, vapour, or spitting. Marketed as a discreet way to consume nicotine, they still deliver a highly addictive substance and expose users to certain chemicals. Health experts have raised concerns, particularly for young people, despite these products often being promoted as a “safer” choice than cigarettes.

Popular brands such as Zyn, On!, and Velo now dominate a fast-growing market, according to the CDC. Like vaping, they do not contain tobacco and are generally viewed as less harmful than smoking.

A recent study led by researchers at University College London (UCL) found that over the past five years, about 522,000 additional people in the UK have started using nicotine pouches, with usage rising from 0.1% to 1% of the adult population.

This has raised an important question: are nicotine pouches actually safer than smoking, and what is driving their sudden popularity?

Nicotine Pouches: Is Using Them Safer Than Smoking?

Speaking on *Mornings with Ridge and Frost*, lead study author Dr Harry Tattan-Birch from UCL’s Institute of Epidemiology and Health Care told Sky News that the risks linked to nicotine pouches are much lower than those associated with smoking. “There’s no tobacco and no combustion,” he explained. “And we know it’s the burning of tobacco that causes most smoking-related diseases.”

That said, Dr Tattan-Birch and his colleagues stressed that these products are not harmless and should never be accessible to children. The NHS notes that while nicotine itself does not cause serious diseases in the way tobacco does, young people’s developing brains and lungs are more vulnerable to its effects, and dependency can form quickly.

UCL research fellow Eve Taylor also told Sky News that nicotine pouches are “far less harmful than smoking,” but cautioned that they are still relatively new. Because of this, their long-term effects are not yet fully understood. “We can look at what’s in them to estimate potential risks,” she said. “They’re not risk-free. Users are still exposed to some toxic substances, even if the levels are much lower.”

Nicotine Pouches: Are Pouches Helping People Quit Smoking?

According to UCL’s findings, among participants surveyed between January 2022 and March 2025, 69% of nicotine pouch users were also using other nicotine products. More than half of them, 56%, were still smoking cigarettes. Around one in six users, or 16%, reported that they had never been regular smokers, suggesting the habit was not linked to quitting cigarettes.

As quoted by Sky News, Dr Tattan-Birch said the public health impact of nicotine pouches depends largely on who is using them. “If a young person who might otherwise smoke switches to pouches, that could reduce harm,” he said. “But if someone who wouldn’t have used nicotine at all starts using them, the risk of harm goes up.”

Researchers added that more studies are needed to understand whether nicotine pouches genuinely help people stop smoking in the long run.

Are Nicotine Patches Harmful For Health?

Nicotine patches are widely regarded as safer than smoking and are a well-established aid for quitting. They provide a steady dose of nicotine to reduce cravings without exposing users to tar or cancer-causing chemicals found in cigarettes. However, they are not completely without side effects. Common issues include skin irritation, headaches, and sleep disturbances. People with serious heart conditions or those who are pregnant are advised to speak with a doctor before using them, as nicotine can still affect heart rate and blood pressure, though far less dangerously than smoking, according to the CDC.

Ozempic (semaglutide) has quickly become a widely used drug for managing type 2 diabetes and supporting weight loss. With its growing use, many people are wondering whether it has any interaction with alcohol. There have also been reports suggesting that Ozempic may reduce alcohol cravings in some users.

While it is not always necessary to completely avoid alcohol while taking Ozempic, doctors say there are certain side effects and risks that should not be ignored. To understand this better, we spoke with Dr Monika Sharma, Senior Consultant in Endocrinology at Aakash Healthcare.

Can Ozempic Make Alcohol Hit Twice as Hard?

Yes, alcohol can feel noticeably stronger when taken alongside medications like Ozempic, and this has a lot to do with how the drug alters digestion, metabolism, and brain signalling. Ozempic belongs to a class of medicines called GLP-1 receptor agonists. It is primarily prescribed for type 2 diabetes and is increasingly used for weight management. One of its key actions is slowing down stomach emptying, meaning that both food and liquids stay in the stomach longer before moving into the intestines.

Dr Sharma explains, “When alcohol is consumed, delayed gastric emptying can lead to uneven absorption. In some people, alcohol enters the bloodstream later but more rapidly once absorption begins, which can raise blood alcohol levels faster and intensify intoxication even with smaller amounts.”

Ozempic and Alcohol: Reduced Appetite and Drinking On An Empty Stomach

Another major factor is appetite suppression. Many people on Ozempic eat significantly less or skip meals altogether, either intentionally or due to reduced hunger. Drinking alcohol on an empty or nearly empty stomach allows it to be absorbed more quickly, as there is little food to slow the process. As a result, an amount of alcohol that once felt manageable may suddenly cause dizziness, flushing, nausea, or loss of coordination much sooner than expected.

Ozempic and Alcohol: Brain Effects and Alcohol Sensitivity

Ozempic also affects areas of the brain linked to reward, fullness, and impulse control. Emerging research suggests that GLP-1 receptor agonists may lower cravings for substances like alcohol, while at the same time increasing sensitivity to its effects. This means that even if the desire to drink decreases, the body’s reaction to alcohol may feel stronger or more unpleasant. Many users report unusual tiredness, light headedness, or nausea after just one drink, often describing it as alcohol “hitting twice as hard.”

Ozempic and Alcohol: Blood Sugar Changes and Hypoglycemia Risk

Blood sugar regulation is another concern. Alcohol can cause fluctuations in glucose levels, and when combined with a medication that tightly controls insulin release and glucose use, the risk of low blood sugar increases, particularly for people with diabetes. Symptoms of hypoglycemia include sweating, shaking, confusion, and palpitations. These signs can resemble alcohol intoxication or worsen its effects, making the experience more intense and potentially dangerous.

Ozempic and Alcohol: Dehydration and Slower Recovery

Dehydration also plays a role. Ozempic can cause side effects such as nausea, vomiting, and reduced fluid intake, all of which increase the risk of dehydration. Alcohol further depletes fluids, and when the body is already low on hydration, alcohol’s impact on the brain and heart becomes stronger. This can lead to faster intoxication, headaches, and a longer recovery time after drinking.

Ozempic and Alcohol: Gut Sensitivity and Worsening Side Effects

Gastrointestinal sensitivity should also be considered. Ozempic commonly causes nausea, bloating, acid reflux, and stomach discomfort, especially in the early months of treatment. Alcohol irritates the stomach lining and relaxes the lower oesophageal sphincter, which can worsen these symptoms. Together, even small amounts of alcohol can trigger stronger negative reactions, reinforcing the feeling that tolerance has suddenly dropped.

Why Alcohol Feels Stronger On Ozempic

While Ozempic does not directly interact with alcohol the way some medications do, its indirect effects on digestion, hydration, metabolism, and the nervous system can make alcohol feel more potent. This is why moderation is strongly advised. People taking Ozempic should limit alcohol intake, avoid drinking on an empty stomach, stay well hydrated, and pay close attention to how their body responds.

In short, Ozempic can make alcohol feel stronger not because it increases alcohol levels directly, but because it changes how the body processes and reacts to alcohol. Being aware of this interaction can help people make safer, more informed choices while using this medication.

Dense, toxic smog covered India’s capital on Monday, driving air pollution to its highest levels in weeks, disrupting travel, and prompting authorities to enforce the strictest containment measures. More than 40 flights were cancelled, with several dozen more delayed. Over 50 trains arriving and departing from New Delhi faced delays of several hours, officials reported. Healthcare experts urged residents to stay indoors as hospitals recorded a surge in patients with breathing problems and irritated eyes. Now, a pulmonologist is warning that indoor air in Delhi might actually be more hazardous than the smog outdoors.

Delhi Pollution: Indoor Air More Toxic Than Outdoor Smog

Indoor air quality in Delhi is reportedly worse than the air outside, according to a lung specialist. Dr. Vivek Nangia, head of pulmonology at Max Healthcare, said indoor spaces can have particulate matter, or PM2.5 levels, nearly two-and-a-half times higher than outdoor readings, even when there are no direct pollution sources indoors.

“Indoor air can be 20 to 30 times more polluted than outdoor air, so it’s important to monitor and improve it,” he explained. Studies have shown that lung-damaging tiny particles inside homes are “substantially higher” than what nearby government monitors report outdoors. This was also confirmed by a study conducted by the Energy Policy Institute at the University of Chicago (EPIC) between 2018 and 2020, which surveyed thousands of Delhi households across different income levels, finding that both rich and poor families are affected equally.

Researchers noted that wealthier households were 13 times more likely to own air purifiers than low-income ones, yet indoor pollution in those homes was only about 10% lower than in disadvantaged settings.

“In Delhi, the bottom line is—whether someone is rich or poor, nobody gets to breathe clean air,” said Dr. Kenneth Lee, the study’s lead author. “It’s a complex, vicious cycle.”

How Does Indoor Air Quality Affect Your Lungs?

Poor indoor air quality (IAQ) can harm the lungs by causing inflammation, weakening the body’s defenses, and triggering or worsening conditions such as asthma and COPD. Pollutants like dust, mold, VOCs, and smoke can lead to coughing, wheezing, infections, and long-term lung damage, even raising the risk of lung cancer over time. Because the lungs are constantly exposed to air, they are extremely sensitive to irritants, which can reduce lung function and capacity—particularly in children, older adults, and those with pre-existing conditions, according to the American Lung Association.

Dr. Nangia noted that patients are now showing a different kind of chest congestion. “These days we’re seeing two kinds of patients—those who never had lung issues before but are now coming in, saying their coughs, sneezing, and chest congestion started once air quality worsened, and those with existing lung problems who are experiencing much worse symptoms,” he said.

How To Protect Yourself From Indoor Toxic Air?

According to the American Lung Association, protecting yourself from indoor air pollution involves controlling sources of pollutants (no smoking, using low-VOC products), improving ventilation (opening windows, using exhaust fans), using HEPA air purifiers, cleaning regularly (dusting and vacuuming), managing humidity to prevent mold, and wearing N95 masks on days with high outdoor pollution to reduce indoor air infiltration.
