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.

Flu has now reached California, officials at the California Department of Public Health (CDPH) confirmed on Tuesday. The mutated influenza strain, which is dubbed as the 'super flu' is now spreading in California.

The CDPH confirmed a second pediatric death related to flu since the season of this respiratory virus had started. The 'super flu' strain is the mutation of seasonal influenza A H3N2 virus, called the subclade K. While the cases are on the rise, with some record breaking ER visits and hospitalizations, the Centers for Disease Control and Prevention (CDC) noted that the season has not peaked yet, and that there might be more cases in the coming week.

What Are The Symptoms Of Super Flu?

Dr Monica Gandhi, who is an infectious disease expert at UC San Francisco told SFGATE that people infected with the mutated strain will likely get common flu symptoms, such as body aches, fever, cough and headache. "I think this particular strain makes people feel pretty horrible," Gandhi said, and further added, "And the reason that subclade K is important is it may not be covered by the current flu vaccine."

However, experts are still asking people to get vaccinated. In fact, the CDC has also noted that vaccination "has been shown to reduce the risk of flu and its potentially serious complications". However, only 130 million doses of vaccine have been distributed, which covers less than 40% of the US population. "The vaccine remains the most effective means to prevent disease. We still want to encourage people to get the vaccine," said Professor Antonia Ho, Professor and Honorary Consultant in Infectious Diseases at the University of Glasgow. Experts have stressed enough on the immunity that one can receive from the vaccine that that these flu jab remain the best defense against the flu, even though the current strain circulated may have drifted away from the strain included in this year's jab.

Data from the UK Health Security Agency (UKHSA) also show that vaccines is performing as expect, despite the emergence of subclade K.

K variant causes more intense flu symptoms, they include:

• Fever
• Chills
• Headache
• Fatigue
• Cough
• Sore throat
• Runny nose

This year's flu came after the flu vaccination was made, which means the current vaccination does not align with the mutation, however, experts have pointed out that it still continues to offer protection against the illness.

Update On Flu Activity

Flu activity in the state has shown a downtick from the season high at the end of the December. 15% of flu tests have come back positive by January 3, which is down from 17% rate seen during the week ending with December 27. However, the CDC noted that this downtick does not mean the end of flu season, it could rather mean that less cases were reported due to the holiday season. As the agency has warned more such cases to show up in the coming week.

In fact, hospitalization have been on the rise and hit a season high with 3.8 admissions per 100,000 in the state as of January 3.

Diabetes isn't just costing Indians their lifelong savings, it's also costing the country INT11.4 trillion.

According to a Nature Medicine study, India faces the second highest economic burden due to this chronic condition. Only the United States ranks higher, with costs touching INT 16.5 trillion, while China comes in third at INT 11 trillion.

While excluding informal care provided by family members, the global costs comes around INT 10 trillion which is about 0.2 per cent of the world’s annual gross domestic product (GDP).

However, if informal care is factored in, costs goes up to INT152 trillion or 1.7 per cent of the world’s yearly GDP, as per the study. (An international dollar, or INT$, is a statistical unit that has the same purchasing power as a US dollar).

The scientists estimated that the economic impact of diabetes was much more than Alzheimer’s disease or cancer in the top three countries.

The Diabetes Crisis In India

Diabetes is a chronic condition affecting several aspects of physical and mental health. It occurs when either the body can’t make enough insulin or can’t use it effectively, which impairs several functions.

Often referred to as the 'Diabetes capital of the world', over 100 million people across India suffer from the chronic condition while another 136 million are living with prediabetes.

According to Pharmeasy 2025 Diabetes Report, one in two people show high blood sugar levels when tested and over 90 percent of reports with high blood sugar also showed abnormality in one or the other parameters for liver, lipid, heart or thyroid issues.

Also known as a 'Silent Killer', diabetes can develop and progress quietly in the body, often without clear or early symptoms. Multiple studies show that over 50 percent of people with diabetes in India are undiagnosed or unaware of their condition.

When left undiagnosed and untreated, diabetes can cause severe complications across the body including heart disease, kidney damage or vision loss. These complications disproportionately affect vulnerable parts of the population, especially those in rural areas without access to proper testing and treatment.

Despite the growing economic burden, India faces systemic challenges in addressing diabetes, including inadequate healthcare infrastructure, low public awareness and fragmented policy responses.

What Did The Study Find?

They evaluated costs based on medical expenses, productivity losses and caregiving.

While the burden in the US is largely due to high treatment costs and loss of physical capital, the high costs are mainly driven by the sheer number of people affected in India and China, the researchers said.

Author Klaus Prettner, professor of macroeconomics and digitalization at the Vienna University of Economics and Business noted of the results: "Caregivers often drop out of the labor market, at least partially, which creates additional economic costs."

"This is a stark illustration of how medical treatment regimes for chronic diseases such as diabetes are accessible to high income countries only," co-author Michael Kuhn, acting economic frontiers research group leader at the International Institute for Applied Systems Analysis, added.

Based on the results, the scientists said promoting healthier lifestyle, regular physical activity and a balanced diet is the most effective way to prevent diabetes and reduce its economic impact in each country in the long run.

Colleen Hoover, the best-selling author of 'Regretting You' and 'Verity', has revealed that she has undergone treatment for cancer.

On January 12, Hoover announced via her Instagram Stories that she has one more day of radiation left at Texas Oncology.

"Second to last day of radiation," she captioned the post on her Instagram Stories. "I wish I could blame my hair and facial expressions on @Texas.Oncology, but they've been great. Hope you never need them, but highly recommend them."

In December 2025, the 46-year-old writer wrote on her Facebook page that she had been diagnosed with cancer and had undergone surgery. The film producer also noted that she would only need radiation, but not chemotherapy as a treatment plan.

Hoover said she had been in Canada filming Reminds of Him when she noticed she “had recurring health issues that I continued to put off until the movie was finished" and a check-up revealed that she had developed cancer.

What Kind Of Cancer Does She Have?

While she is yet to reveal which kind of cancer she is receiving treatment for, Hoover has confirmed it was not caused by family genes, HPV or excessive hormones.

In a Facebook post from January 9, she noted that the reason for her illness is 'more than likely' to be environmental/lifestyle, which can be credited to a lack of exercise, poor diet and stress.

"I’m happy and grateful to be alive but I hate vegetables. I hate when I have to get off the couch. I hate sweating. I hate when science is right. If you see me at the gym, don’t even tell me good job. If you see me at a restaurant eating grilled chicken and drinking water, I’m probably real mad about it," she wrote in a heartfelt moment.

Why Has Hoover Been Missing From Public Eye?

Hoover's health updates and cancer treatment come amid a series of cancelled public events. In October 2025, she announced she would not attend the premiere of Regretting You, her latest movie adaptation.

In a sentimental Instagram post, she told her fans: "I’m super bummed, but am having an unavoidable surgery and can’t travel for a while,” Hoover wrote in her Instagram post at the time. I’ll live vicariously through you guys. So sad to miss this movie release and premiere, but so grateful to all the actors and the team who put this together.”

Woman Down is Hoover’s next book release set for January 13. However, the author has had to tell fans that a book-signing tour has not been set up yet and she will not be meeting with the public for now.

“I wanted to make this post and be transparent about why that is. I’m not saying I won’t be up to doing at least one signing, but I just won’t know until I know," she said.

Meanwhile, throughout 2025, production on her hit novel, Verity, has begun in 2025, with Anne Hathaway and Josh Hartnett, being photographed during scenes last February. Additionally, her third movie adaptation, Reminders of Him, is also set to hit theaters on March 13, 2026.

It remains unknown if she will be attending the premiere for Reminders of Him.
