Mysterious Fog in the US , Canada and UK: A dense, eerie fog with a "burning chemical-like smell" has spooked a good part of North America and parts of the United Kingdom and Canada. With social media amplifying all concerns, this phenomenon has sparked attention across all social media platforms. However, at the heart of this mysterious fog are a conjunction of natural events, social psychology, and environmental conditions that culminated in all the conspiracy theories and public health fears. Here's a closer look at the mysterious fog, its potential causes, and the societal response it has triggered.

Fog that Feeds Fear

The first reports of this "mysterious fog" came in from Florida where a resident said that they experienced respiratory symptoms, feverish warmth, and stomach cramps after contact with the fog. Similar stories started flooding social media, and within a day or two, a sinister force seemed to sweep across the United States, Canada, and parts of the UK. From Texas to Minnesota, people reported weird odors and health issues that they thought were linked to this bizarre atmospheric event.

Some witnesses were said to see "white particles" swirling through the air; theories ranged from a chemical attack or experimental weapon to drone-related chemical dispersals and references to historical military experiments, such as the infamous 1950s "Operation Sea-Spray."

Fuel to the fire were added when videos and posts, hundreds of thousands in number, began circulating on social media sites like TikTok and X (formerly Twitter) speculating on the origin of the fog. Hashtags like #ToxicFog went trending for days. Hysteria created a self-reinforcing loop in which every post spurred further scrutiny and fear.

Scientific Explanation of the Dense Mysterious Fog

1. What is Fog?

Fog is essentially a low-lying cloud formed when the air temperature cools to its dew point, causing water vapor to condense into tiny droplets or ice crystals. Several types of fog—advection fog, radiation fog, and valley fog—can form depending on conditions such as warm, moist air moving over cooler land or when temperatures plummet rapidly under clear skies.

2. Why the Chemical Smell?

Such chemical-like smell as reported during the occurrence of fog events is sometimes attributed to air pollution. It acts like a sponge, where it absorbs these pollutants, which include sulfur dioxide and nitrogen oxides, among others, that emit from industries. This mixture, therefore, leads to a stench that could be mistaken as unnatural or even toxic.

3. What are the Health Concerns?

High moisture levels from fog can significantly exacerbate symptoms related to respiration, but especially in already predisposed asthmatics and allergy patients. The connection of these symptoms with actual fever, stomach cramps, and puffy eyes is too remote. Experts assume that the irritating effects of entrapped pollutants trapped in fog tend to affect more the eyes and throat rather than the rest of the body affected by some report.

Psychological Effects of Mass Panic Caused by Social Media

Social media amplified a natural weather event into a health epidemic. It made the personal experience of individuals become a cause for fear and speculation, a domino effect.

According to psychologists, this is a concept of selective perception, wherein once people's attention is drawn to environmental anomalies, they begin to notice them. This mirrors earlier panics, such as the Seattle windshield pitting panic of 1954. Then, atomic bomb testing caused fear in many and started to have people looking at their windshields for small marks that they had not seen before. Likewise, postings on the strangeness of the fog probably increased public awareness and suspicion, with people looking to attach unrelated symptoms to the phenomenon.

The fog hysteria shares a commonality with other instances of mass panic, such as the "drone sightings" of recent years or the Cold War-era fears of biological warfare.

These events underscore how fear can cloud judgment, especially when amplified by social media and sensationalist headlines. While historical cases, such as "Operation Sea-Spray," offer concrete evidence of the existence of unethical experiments, the jump from a natural weather condition to theories of chemical attacks exemplifies a more modern trend of connecting unrelated dots, all wonderfully seeded in distrust and anxiety.

Despite the swirling rumors, meteorologists and scientists are in agreement that the mysterious fog is not as alarming as it seems. It is well known that fog traps and amplifies pollutants, especially in urban and industrial regions. Moreover, winter months are the most conducive for fog formation, so its recent prevalence is unsurprising.

On the other hand, environmentalists advise that the fog should wake everyone up to increased levels of pollution. The reported odors and health irritations could be just symptoms of far deeper systemic issues like industrial emissions and lack of control over air quality.

The authorities must be transparent in their communication to combat misinformation and allay public fears. Governments and environmental agencies must provide timely updates on weather phenomena, air quality, and health risks. Initiatives like real-time pollutant tracking and public education campaigns can help demystify natural occurrences while addressing valid environmental concerns.

The mysterious Canada fog is a compelling case study in how environmental events intersect with psychology and societal dynamics. While rooted in natural phenomena, the fog became a vessel for collective fears, amplified by modern technology and historical anxieties.

In this information era where communication occurs at an almost lightning pace, the fog becomes a metaphor that reminds everyone about scientific literacy, environmental responsibility, and an effective balance when considering public concern. Whether perceived as a marvel of nature or as a tale that serves to teach, it left a very powerful mark in people's minds.

India is undergoing a steady but serious public health shift. For decades, obesity was long dismissed as a matter of personal discipline, a “lifestyle choice,” to be managed by sheer willpower.

However, it has emerged as a progressive, chronic disease with complex biological roots that demand sustained medical care, which is no longer confined to urban centers. It now affects smaller towns and rural communities alike. The National Family Health Survey (NFHS-5) reports that nearly one in four Indian adults is overweight or obese.

The situation in children is even more alarming, as UNICEF estimates that by 2030, India could have more than 27 million children and adolescents aged 5-19 years living with obesity, which would account for 11 percent of the world’s burden and put millions at risk of early metabolic disease.

Yet obesity continues to be viewed largely as a lifestyle lapse rather than a chronic, relapsing condition shaped by genetics, environment, and metabolic dysfunction. Like diabetes or hypertension, it progresses over time and requires structured, long-term medical management.

The Pediatric Crisis And The Looming Public Health Debt

The clearest sign of how serious this problem has become is visible among children. Recent findings published in The Lancet estimate that more than 12.5 million Indian children are living with obesity. This is not a distant warning; it is unfolding in clinics across the country.

Longer screen time, easy access to high-calorie packaged food, shrinking playgrounds, and limited physical activity have steadily altered childhood routines. As a result, pediatricians are diagnosing Type 2 diabetes, fatty liver disease, and hypertension in teenagers, conditions that were once largely confined to middle age.

When excess weight and metabolic imbalance begin in adolescence, the health impact stretches across decades. These children are likely to carry obesity into adulthood, along with a higher risk of heart disease, kidney disorders, and other chronic illnesses.

The burden is not just medical; it affects education, productivity, and long-term quality of life. Tackling this trend demands more than occasional awareness drives. It calls for consistent screening, early counselling, family-based lifestyle changes, and structured metabolic monitoring from a young age.

The GLP-1 Revolution And The Medical Oversight

The rise of GLP-1 receptor agonists has reshaped the discussion around obesity treatment in India. After the January 2026 patent expiry of semaglutide, more affordable generics have widened access, particularly for middle-income patients.

Clinically, these medications have clear advantages, as they decrease appetite, enhance insulin sensitivity, and have demonstrated durable weight loss and cardiovascular risk reduction in large international trials published in The New England Journal of Medicine.

However, increased availability has also fueled cosmetic and unsupervised use. GLP-1 therapies were developed to treat metabolic disease, not for short-term aesthetic goals. They act on hormonal pathways that regulate hunger and glucose metabolism, making them potent medical agents.

Without proper evaluation, dose monitoring, and long-term planning, patients may experience gastrointestinal side effects, muscle loss, or weight regain after discontinuation.

In a country like India, where obesity often coexists with advanced diabetes and heart disease risk, these medications must remain part of a structured, physician-led plan. They are an important therapeutic option, but not a substitute for sustained lifestyle and metabolic care.

The Inevitable Link to Non-Communicable Diseases

Obesity should be recognized as a chronic disease, as it is the underlying cause for most of the non-communicable diseases in India. According to the Global Burden of Disease report, ischemic heart disease is one of the top causes of death in India, and obesity is a direct contributor to this.

Visceral fat is associated with systemic inflammation, insulin resistance, abnormal lipid levels, and hypertension, which are the major pathways that cause heart attacks, strokes, and kidney diseases.

Visceral fat is also associated with an increased risk of colon cancer and post-menopausal breast cancer, which are being increasingly noticed in young Indians.

Adding to the complexity is the Indian “thin-fat” phenotype, in which individuals with a normal BMI can have high internal fat. Thus, in the treatment of obesity, one has to treat the metabolic problem rather than just the appearance alone.

Recognizing it as a chronic disease shifts focus toward early detection, sustained therapy, and long-term follow-up, which are essential steps to reduce premature cardiovascular deaths in India’s working-age population.

A Path Towards Holistic Intervention

Managing a chronic disease is not just about a prescription; it is about an ecosystem of care." A truly effective solution would have to be multi-modal, which means combining precision nutrition that takes into account the Indian eating habits, as calorie restriction alone would not be effective because it does not address the hormonal regulation, behavioral patterns, psychological triggers, or the metabolic imbalance.

An effective approach combines medical nutrition therapy, supervised physical activity, behavioral counselling, pharmacotherapy when indicated, and metabolic or bariatric surgery for eligible patients. Surgical intervention, supported by long-term data, not only reduces weight but also induces remission of Type 2 diabetes in a significant proportion of patients.

The goal is to transition from "weight loss" to "metabolic restoration." By treating obesity with the same clinical rigor as any other chronic disease, the healthcare industry can finally move beyond the scale and begin saving lives through comprehensive, science-based intervention.

The US Centers for Disease Control and Prevention (CDC) has issued an immediate recall of contaminated Rosabella brand moringa powder capsules that are tied to an outbreak of drug-resistant Salmonella infections, causing fever, diarrhea (which may be bloody), nausea, vomiting, and abdominal pain.

This is the second Salmonella outbreak related to moringa powder in the past six months. However, the two cases are not related, the CDC said.

In its latest alert issued in February 2026, the CDC reported seven cases, including three hospitalizations, from seven states linked to Rosabella brand moringa powder capsules.

The agency noted that the capsules distributed by Ambrosia Brands LLC, which is based in the US, are contaminated with Salmonella Newport and have led to one case each in states including Arizona, Florida, Iowa, Illinois, Indiana, Tennessee, and Washington.

"CDC, public health and regulatory officials in several states, and the US Food and Drug Administration (FDA) are collecting different types of data to investigate a multistate outbreak of multidrug-resistant Salmonella Newport infections,” the CDC said.

"Epidemiologic data show that Rosabella brand moringa powder capsules may be contaminated with Salmonella Newport and may be making people sick,” it added.

What The CDC Investigation Found

The median age of the affected patients is 66 years, and 86 percent are females.

The public health officials also conducted a whole-genome sequencing of the seven samples.

The tests revealed that the Salmonella strain associated with this outbreak is resistant to all first-line and alternative antibiotics commonly recommended for the treatment of Salmonella infections.

"This strain also might be resistant to multiple β-lactam antibiotics, including meropenem and other carbapenems, because it carries an NDM-1 carbapenemase gene," the CDC said.

As Salmonella illnesses may not be treatable with commonly recommended antibiotics, the CDC advised to "tailor antibiotic treatment to antimicrobial susceptibility testing results when possible".

Issuing a recall, the CDC stated the capsules are sold on the company's website, Amazon, TikTok Shop, Shein, and eBay.

"If you have any of these capsules in your home, throw them out or return them. CDC and FDA continue to work to identify if there are other products causing illness in this outbreak,” the regulator said.

In January, the regulator had reported an investigation of a Salmonella outbreak linked to dietary supplements containing moringa leaf powder.

What Is The Salmonella Infection?

Food contamination with Salmonella -- an organism -- can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems.

The CDC noted that in rare cases, the organism can get into the bloodstream and produce more severe illnesses such as arterial infections (i.e., infected aneurysms), endocarditis, and arthritis.

Salmonella Newport, detected in the recent outbreak, is a serious, often multidrug-resistant (MDR) bacterium causing human and animal illnesses. It also ranks among the top three Salmonella serotypes in US foodborne outbreaks.

Noida administration has launched a 10-day measles-rubella (MMR) vaccination drive with an aim to cover students from Classes 1 to 5 across government and private schools. UP State Health Department officials noted that the sessions are also being conducted within the school premises under this campaign to ensure a wider vaccination coverage and ease of access for students and parents.

The initiative is part of the state government's ongoing efforts to strengthen immunity against measles and rubella. It is a highly contagious viral disease that primarily affects children.

Under the Measles-Rubella elimination campaign, the Central government aims to reach 100 per cent immunization coverage by ensuring children receive both doses of the vaccine. According to the 2024–25 Health Management Information System, India’s MMR coverage is currently 93.7 per cent for the first dose and 92.2 per cent for the second.

“The objective is to ensure that no eligible child is left out. Children will be administered an additional dose of the MR vaccine during the campaign. The vaccine is safe and is being provided for free of cost,” Dr Narendra Kumar, Chief Medical Officer of Gautam Buddha Nagar, told the media persons.

What Is Measles?

Measles is a highly contagious disease. It spreads by coughs or sneezes or by touching things that someone with measles has coughed or sneezed on.

Measles, also known as rubeola, is an extremely contagious viral illness that typically causes high fever, cough, runny nose, red and watery eyes, and a characteristic rash that begins on the face and spreads downward across the body. It spreads through respiratory droplets and can lead to severe and sometimes fatal complications, including pneumonia and inflammation of the brain known as encephalitis.

Symptoms include high fever, sore or red and watery eyes, coughing, sneezing, and small white spots in the mouth.

What Are The Symptoms Of Measles

Measles has a high transmissibility, and high measles immunity levels are required to prevent sustained measles virus transmission.

This is why herd immunity for measles could be easily breached.

It easily spreads from one infected person to another through breathes, coughs or sneezes and could cause severe disease, complications, and even death.

Symptoms include:

• High fever
• Cough
• Runny Nose
• Rash all over the body

The most unique symptom or the early sign of measles in the Koplik spots. These are tiny white dots that look like grains of salt on red gums inside the cheeks that appear before the red rash starts to appear on a person's face and then the body.

Furthermore, the symptoms of measles are also characterized by the three Cs:

• Cough
• Coryza or runny nose
• Conjunctivitis or red and water eyes

How Long Does The Infection Last?

The progression of the symptom comes in two stages, first is the prodromal stage or Days 1 to 4, where one would notice high fever, cough, runny nose, red and watery eyes, sore throat, fatigue, and Koplik spots.

The second stage is called the rash stage or the days 5 to 10 or even more where rash start to appear on the hairline, and then it runs down the body. It lasts for several days and fades in the same order.

The first symptoms, notes the Centers for Disease Control and Prevention (CDC), appear 7 to 14 days after a measles infection. Often, it could also lead to ear infection, or even diarrhea. Though these complications happen in every 1 in 10 children or individual with measles.
