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’s Union Ministry of Health and Family Welfare has issued a notification ending the over-the-counter (OTC) sale of all syrups, including cough syrups.

Under the new rules, a doctor's prescription will now be required to purchase cough syrups across the country.

“Consequently, the sale and dispensing of cough syrups in smaller villages will now be required to take place only through duly licensed pharmacies in accordance with the provisions of the Drugs and Cosmetics Act, 1940 and the Rules framed thereunder,” the notification said.

Why Are the Rules Being Amended?

The amendment comes months after contaminated cough syrups were linked to the deaths of 22 children in Madhya Pradesh and Rajasthan, raising fresh concerns over the safety and regulation of commonly used liquid medicines.

Following the incident last year, health authorities in India had banned three cough syrups Coldrif, Respifresh TR and ReLife after traces of diethylene glycol (DEG) were detected in the products. The Coldrif contamination was linked to the deaths of 22 children in the country.

“The amendment has been undertaken to strengthen regulatory oversight of syrup formulations and to align the exemption framework with contemporary public health and safety requirements,” the notification said.

“The measure is expected to promote responsible distribution and sale of cough syrups while ensuring greater compliance with regulatory standards across the country,” it added.

Experts Welcome Move To Restrict Cough Syrup Sales

Dr Kuldeep Kumar Grover, Associate Director, Pulmonology and Critical Care, CK Birla Hospital, Gurugram called it a

"a good initiative to include all syrup varieties, cough syrups included, under prescription medicines".

Cough syrups have substances that might lead to drowsiness, addiction, or drug interaction in patients who do not seek medical advice before taking the medicines.

"It is important to note that a cough could be a symptom of other serious conditions like infections, asthma, and allergies. Prescription-based access encourages proper evaluation, accurate treatment, and safer medication use," Grover said.

Dr. (Prof.) Mohsin Wali, former Physician to the President of India, said cough syrups and similar formulations often contain suppressants such as codeine and dextromethorphan (DXM), along with other solvents.

Dr. Wali, Senior Consultant and Head of Preventive Cardiology at Pacific One Health, recalled previous incidents in which contaminated Indian-made cough syrups were linked to deaths in Gambia and other African countries.

"Industrial-grade solvents were detected in some of these products, leading to kidney failure, severe metabolic acidosis, and, in some cases, death," he said.

According to Dr. Wali, the new notification will help curb the overuse, misuse, and addictive use of cough syrups while improving patient safety.

What Did The Notification Say?

The Ministry notified an amendment to the Drugs Rules, 1945, through Gazette Notification G.S.R. 927(E) dated December 29, 2025, published in the Gazette of India Extraordinary, Part II, Section 3, Sub-section (i), dated December 30, 2025.

The amendment omits the word “Syrup” from Schedule K, Serial No. 13, Entry 7 under the heading “Class of Drugs.”

Schedule K of the Drugs Rules, 1945, provides exemptions from certain provisions of the Drugs and Cosmetics Act, 1940, and the rules framed under it for specified classes of drugs.

Before this amendment, Entry No. 13 of Schedule K permitted the sale of cough syrups in villages with a population of less than 1,000 without requiring compliance with certain retail sale licensing provisions.

With the omission of the word “Syrup” from the entry, this exemption will no longer apply to cough syrups.

Manufacturers, distributors, and retailers dealing with cough syrups have been advised to ensure strict compliance with the applicable licensing and regulatory requirements under the Drugs and Cosmetics Act, 1940, and the Drugs Rules, 1945.

Ban On Pediatric Cough Syrups

Last year, India formally prohibited the use of certain commonly available OTC cough and cold medicines in children below the age of four.

The policy move, notified through a gazette notification, banned a fixed-dose combination (FDC) of Chlorpheniramine Maleate and Phenylephrine Hydrochloride—two ingredients commonly found in pediatric cough syrups.

The decision followed growing global concerns over the safety of these medicines in very young children, with India joining several countries that have introduced stricter regulations.

Countries including the United States, Canada, and the United Kingdom had previously issued guidelines or warnings regarding the use of OTC cough and cold medicines in young children.

One month has passed since the Democratic Republic of the Congo (DRC) declared its 17th Ebola outbreak, and there is no sign of respite. Confirmed cases and deaths have surged to 808 and 192, respectively, according to the country's Health Ministry.

Uganda has confirmed 19 infections, while Congo's Ituri province, where the outbreak first emerged, accounts for more than 90% of cases in the country.

The outbreak was reported to the World Health Organization (WHO) and the outbreak was officially declared on May 15.

The cases continue to surge daily as health authorities and aid agencies grapple with inadequate testing, weak contact tracing, and community resistance.

However, experts warn the outbreak's true scale may be far greater than official data indicate, making it already the third-deadliest Ebola outbreak on record.

Ebola Epidemic Moving Upward

According to Dieudonne Mwamba Kazadi, head of the DRC National Institute of Public Health (INSP), the Ebola epidemic was still moving upward in Bunia, the capital of Ituri province and the epicenter of the outbreak, Xinhua News Agency reported.

"We are still in the midst of the epidemic. I would say we are in the upward phase of the outbreak, the active phase," Kazadi said.

More confirmed cases are expected in the coming days, making it urgent to expand treatment capacity and establish new Ebola treatment centers in affected areas, he noted.

"The perspective is really to increase capacity and already have treatment centers positioned to receive the future suspected and confirmed cases that we will identify in the coming days and weeks," Kazadi said, stressing the need to "engaging communities further," he said.

True Scale of Outbreak Remains Unclear

Medical charity Medecins Sans Frontieres (MSF) said in a statement that the government's figures likely understate the true toll of the outbreak, echoing concerns raised by aid groups and some Congolese officials.

"No one knows the true scale or exactly where the disease is spreading in DRC," said Kate White, MSF's emergency medical coordinator.

"One month on, the Ebola disease outbreak is outpacing the response effort," White said.

She noted that most treatment centers in Ituri province are overwhelmed, with many patients arriving at a late stage of the disease.

"What we do know is that most treatment centers in Ituri province are overwhelmed; many of our patients arrive at a late stage of the disease, and the majority were never identified or monitored as contacts before seeking care," White said.

Testing and Contact Tracing Challenges

Testing remains "one of the most significant weaknesses in the response," according to the MSF statement.

WHO Director-General Tedros Adhanom Ghebreyesus said he was “really worried” about the outbreak after visiting the DRC, Stat News reported.

“When the community is not taking it as its priority, it’s very hard,’’ Tedros said. He said that in the North Kivu, South Kivu, and Ituri provinces where the outbreak is centered, Ebola is seen as a lesser evil compared with armed conflict, widespread hunger, and more common deadly diseases experienced daily.

Notably, many communities, particularly those affected by active armed conflict, still lack access to test kits. Treatment centers are also facing significant delays in receiving laboratory results, hampering efforts to quickly identify and isolate infections.

What Is Ebola?

Ebola is a highly lethal viral hemorrhagic fever first identified in 1976. Over the past five decades, it has caused over 30 outbreaks, primarily in Central and West Africa.

Symptoms include fever, headache, weakness, vomiting, diarrhea, muscle pain, sore throat, and unexplained bleeding. This eventually leads to severe complications like bleeding, organ failure, and death.

Aid groups warn that without stronger surveillance, faster testing, and improved contact tracing, the outbreak could continue to expand in the weeks ahead.

The United Kingdom is planning to create a new normal for children by banning social media for kids under 16. The services of social media, including Instagram and Snapchat, will not be available for adolescents in the island nation. The government there is planning to follow in the steps of Australia and block social media to ensure a safe and secure childhood.

To better protect children online and tackle growing digital risks, the government plans to introduce measures that go beyond a simple social media ban. Under the proposal, children under 16 would be blocked from accessing high-risk features such as livestreaming and communicating with strangers online. These world-leading restrictions would extend beyond social media platforms to cover a broader range of online services, including gaming websites, making the policy one of the most comprehensive child online safety measures introduced anywhere in the world.

Prime Minister Keir Starmer said, Parents want to keep their kids safe and happy, but the online world has made that harder than ever." He added, "I’ve heard firsthand from families crying out for change, and we will do right by them."

He also said that any country can ban social media for under-16s and put wider protections in place to give kids their childhood back.
