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.

Wegovy pill by Novo Nordisk is now under scrutiny after the US Food and Drug Administration (FDA) raised concerns over a television advertisement. FDA said that the commercial includes "false and misleading" claims about the obesity drug's benefits.

In a letter (reported first by Bloomberg) dated February 5, the FDA said the advertisement misbrands the oral weight loss drug. FDA said that it made its distribution a potential violation of federal law. FDA has asked the Danish drugmaker to take immediate corrective action, which include:

• Pulling the ad
• Revising all advertisements that contain misleading statements

Wegovy Pill: FDA Questions Claims of Superiority and Emotional Benefits

As per the letter, the FDA found that the ad misleadingly suggests the Wegovy pill offers superior benefits when compared to other approved GLP-1 weight loss drugs. The regulator flagged phrases such as “live lighter” and “a way forward,” saying they imply greater weight loss and added advantages without evidence to support those claims.

The FDA also took issue with what it describes as emotional and psychological messaging, saying that the ad appears to imply benefits beyond physical weight loss, including emotional relief, reduced psychological burden, hope, or direction in life. FDA notes that this claim positions the drug as a solution to broader life challenges rather than just a treatment to obesity.

Furthermore, FDA said that the ad failed to adequately present risk information in both audio and text formats, which is mandatory requirement for television drug advertising.

Wegovy Pill: Novo Nordisk Responds To FDA Notice

Novo Nordisk confirmed on Monday that it has received the FDA’s letter. The company clarified that while the advertisement has been running since the pill’s launch, it is not linked to its Super Bowl advertising.

“We take all regulatory feedback seriously and are in the process of responding to the FDA to address their concerns regarding the advertisement’s presentation,” said Liz Skrbkova, Novo Nordisk’s head of US media and stakeholder relations, in a statement.

Novo Nordisk is already under pressure to defend its position in the weight loss market, as it is facing a stiff competition from rival Eli Lilly. Furthermore, on Monday, Novo also filed a lawsuit against telehealth company Hims & Hers, seeking to block the mass marketing of compounded versions of its Wegovy pill and injections.

Wegovy Pill: How Effective Is It?

After injection by Novo Nordisk, of the same name, Wegovy, which has been on the market since 2021, its popularity grew so much that it was in short supply until February 2025. The pill version has now come out, which many experts believe will expand its accessibility. As the monthly supply of pill is expected to be cheaper than the monthly supply of the weight loss injection.

A study published in the New England Journal of Medicine show that a 25 milligram Wegovy pill led to 13.6% reduction in weight on average over 64 weeks. When compared to placebo, the result was only 2.2% of weight loss. Novo Nordisk says that those who stayed on the treatment and reduced their calorie intake, it would lead to a loss of 16.6% of their weight.

Wegovy Pill: What Are The Side Effects?

Digestive problems such as nausea and vomiting remain the most common side effects of GLP-1 drugs. These issues were also reported in studies of the pill versions. Around 7 percent of participants taking the Wegovy pill stopped treatment because of side effects, compared with 6 percent in the placebo group. In orforglipron’s trial, up to 10 percent of patients discontinued treatment, compared with 3 percent on placebo.

One key difference lies in how the medications are used. The Wegovy pill must be taken on an empty stomach with a small amount of water. Patients are advised not to eat, drink, or take other medicines for at least 30 minutes afterward. Doctors say this requirement has limited the use of Rybelsus, the pill form of semaglutide approved for diabetes, compared with Ozempic.

Two years before Jeffrey Epstein killed himself in his New York jail cell, he claimed that US President Donald Trump may be suffering from dementia.

The United States Department of Justice recently released more of the harrowing Epstein Files that lift the lid on years' worth of horrific crimes committed by the convicted American child sex offender, serial rapist and human trafficker.

Among the files, eagle eyed readers found an email sent to journalist and Trump biographer Michael Wolff on Dec. 29, 2017, where Epstein claimed that Trump has begun showing signs of memory loss during his first presidency after he failed to recognize some of his own friends.

In the email to the Landslide author, the convict wrote: "Some at dinner with donald last night, were concerned about dementia. tons of makeup. did not recognize old friends.”

And Epstein isn't alone. Former White House chief strategist and Trump associate, Steve Bannon allegedly believed the president had "early-stage dementia," according to former 60 Minutes producer Ira Rosen’s book Ticking Clock.

Bannon claimed that Donald “had no attention span, didn't read, and now doesn't listen. He said Donald repeats himself a lot, telling the same story minutes after he told it before," per Rosen's account, which the former chief strategist later denied.

The producer also claimed in the book that “Bannon tried to build support to have Trump removed” from office due to his concerns.

Family Members Say Trump Has Dementia

Mary Trump, a well-known critic of her uncle who frequently speaks about him on her YouTube channel, has implied that he could be suffering from Alzheimer's disease, noting similarities to her late grandfather, who also suffered from the neurodegenerative disease.

As per UK Express, Mary highlighted that she has seen resemblances to Fred Trump, Donald's late father and former real estate magnate, who battled Alzheimer’s before passing away in 1999 at the age of 93.

Speaking last year, Mary recounted witnessing her grandfather’s decline and suggested that Donald sometimes doesn’t seem “oriented,” pointing to a particular look. Talking about her grandfather, she told New York Magazine: "One of the first times I noticed it was at some event where he was being honored. And I looked at him and saw this deer-in-the-headlights look, like he had no idea where he was."

In further remarks, Mary said she now notices what the publication described as “flashes” of her grandfather in her uncle when she sees him on stage, pointing out the same “deer-in-the-headlights” expression.

She added: "Sometimes it does not seem like he's aware of time or place. And on occasion, I do see that deer-in-the-headlights look."

Trump Rejects Memory Loss Claims

Despite multiple reports, Trump and his team have consistently rejected such claims, noting that he has “aced” three cognitive tests and there is no possibility of him having Alzheimer's disease.

In a conversation with the New York Magazine, Trump also reflected on his father’s diagnosis: "He had one problem. At a certain age, about 86, 87, he started getting what do they call it?"

His press secretary, Karoline Leavitt, supplied the term for Trump, who referred to it as an “Alzheimer’s thing,” asserting that he did not “have it.” The health of the 79-year-old has been the subject of much public speculation recently, with observers noting bruises on his hands, what appear to be swollen ankles, and rambling speech.

What Is Alzheimer’s Disease?

Alzheimer's disease is one of the most common forms of dementia and mostly affects adults over the age of 65.

About 8.8 million Indians aged 60 and above are estimated to being living with Alzheimer's disease. Over seven million people in the US 65 and older live with the condition and over 100,00 die from it annually.

Alzheimer's disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate in the brain and damage cells responsible for memory.

Amyloid protein molecules stick together in brain cells, forming clumps called plaques. At the same time, tau proteins twist together in fiber-like strands called tangles. The plaques and tangles block the brain's neurons from sending electrical and chemical signals back and forth.

Over time, this disruption causes permanent damage in the brain that leads to Alzheimer's disease and dementia, causing patients to lose their ability to speak, care for themselves or even respond to the world around them.

While there is no clear cause of Alzheimer's disease, experts believe it can develop due to genetic mutations and lifestyle choices, such as physical inactivity, unhealthy diet and social isolation.

Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Over time, Alzheimer's disease leads to serious memory loss and affects a person's ability to do everyday tasks.

There is no cure to this progressive brain disorder and in advanced stages, loss of brain function can cause dehydration, poor nutrition or infection. These complications can result in death.

Health officials in Washington, D.C. are warning that confirmed cases of measles may have spread during this year’s National March for Life rally and related events held in the capital late January. The annual anti-abortion gathering drew thousands of people to the National Mall and surrounding areas, raising concerns about potential large-scale exposure.

The D.C. Department of Health said it is actively working to identify individuals who may be at risk after learning that several people who later tested positive for measles were present in the city while contagious.

“DC Health was notified of multiple confirmed cases of measles whose carriers visited multiple locations in the District while contagious,” the agency said in a statement on Sunday. Officials are now contacting people who were at those locations during the exposure window.

Measles In DC: Transit Hubs and Campuses Among Exposure Sites

According to DC Health, potential exposure sites span a wide range of busy public locations between January 21 and February 2. These include Ronald Reagan Washington National Airport, Union Station, an Amtrak Northeast Regional train, and multiple stops within the city’s Metro subway system.

Health officials also flagged visits to the Basilica of the National Shrine of the Immaculate Conception and Catholic University as part of the exposure timeline. Given the volume of visitors moving through these spaces daily, authorities say the risk of wider spread cannot be ruled out.

Measles In DC: Hospital Issues Public Health Notice

Children’s National Hospital has also issued a public health notice after a confirmed measles patient from Virginia visited its Emergency Department on February 2 while infectious. The hospital said it is coordinating with public health authorities to identify and notify anyone who may have been exposed during that time.

Measles is highly contagious and can remain airborne for up to two hours after an infected person leaves an area, making hospital settings particularly vulnerable.

Measles In DC: Surge Across the United States

The situation in Washington comes as the United States faces its largest measles outbreak in decades. According to the Centers for Disease Control and Prevention, 733 confirmed cases have been reported across 20 states so far this year. The CDC says about 95 percent of those cases involve people who were unvaccinated or whose vaccination status is unknown.

South Carolina remains one of the hardest-hit states. Its outbreak began in October 2025 and has now surpassed earlier outbreaks elsewhere in the country. State health officials reported 44 new cases on Friday, bringing the total to 920. While the pace of new cases has slowed slightly, officials continue to warn of possible exposure at public places such as a Target store in Taylors and a Social Security Administration office in Spartanburg, where the outbreak is centered.

Measles In DC: Vaccination Urged Amid Global Concern

Speaking on CNN’s State of the Union, Centers for Medicare and Medicaid Services Administrator Mehmet Oz urged Americans to get vaccinated against measles. While recent federal policy changes have rolled back recommendations for some vaccines, guidance on measles immunization remains unchanged.

International health authorities are also watching closely. The World Health Organization’s Pan American Health Organization has invited U.S. officials to a meeting in April to review the country’s measles elimination status, which is now under threat.

D.C. health officials are urging anyone who may have been exposed and is not fully vaccinated, pregnant, or immunocompromised to contact a healthcare provider immediately.
