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.

The Union Ministry of Health and Family Welfare has proposed three separate amendments to the Drugs Rules, 1945, to strengthen pharmaceutical quality control, manufacturing accountability and patient safety.

The proposals include immediate suspension of manufacturing licences for drugs failing specified critical quality tests, stricter microbial monitoring in sterile manufacturing areas, and mandatory authorisation of qualified personnel for batch release.

The announcements aim to strengthen India's drug regulatory framework and align manufacturing standards with international guidelines.

Immediate Suspension Of Licences For Drugs Failing Critical Quality Tests

In a significant move to enable faster action against substandard medicines, the Ministry has proposed immediate suspension of manufacturing licences for drugs declared Not of Standard Quality (NSQ) on specified critical parameters.

Under the existing provisions, suspension or cancellation of a manufacturing licence involves a prescribed regulatory process, including the issuance of a show-cause notice. This can create a time gap between the identification of a quality failure and regulatory action, during which the drug may remain in circulation.

To address this, the proposed amendment would allow the Central Licensing Approving Authority or the State Licensing Authority, as applicable, to immediately suspend the manufacturing licence upon receiving a Government Analyst's report declaring a drug NSQ on any of the following parameters:

• Assay
• Dissolution
• Related substances
• Impurities
• Sterility

These parameters are critical to determining the quality and safety of medicines. The proposed provision seeks to enable prompt intervention and minimise potential risks to patients.

Stricter Microbial Monitoring In Sterile Drug Manufacturing

The Ministry has proposed amendments to Schedule M of the Drugs Rules, 1945, to revise microbial contamination limits in Grade A clean areas in line with the World Health Organization's (WHO) Good Manufacturing Practices (GMP) guidelines for sterile pharmaceutical products.

Grade A areas are critical zones in sterile pharmaceutical manufacturing, where exposed products, containers and sterilised components are handled. Maintaining strict microbial controls in these areas is essential to preventing contamination and ensuring product safety.

The proposed revision addresses differences between the existing Schedule M requirements and WHO guidelines. It also provides for any microbial growth detected in Grade A areas to trigger an investigation, in accordance with WHO guidance.

The amendment aims to strengthen contamination monitoring and bring India's sterile manufacturing standards in line with internationally recognised benchmarks.

The development comes in the backdrop of an episode involving India’s biggest drug maker Sun Pharma, which was recently ordered to halt production at its manufacturing plant in Assam after reports of contamination in some of the eye drops made there.

Mandatory Authorization For Drug Batch Release

In another proposal, the Ministry has sought to make it mandatory for drug manufacturers to formally designate a suitably qualified and experienced person responsible for batch release.

Although manufacturers are currently required to provide details of competent technical staff responsible for manufacturing and testing while applying for licences, the rules do not specifically require them to identify the person authorised to release drug batches.

Under the proposed framework, manufacturers applying for licences under the relevant provisions of the Drugs Rules, 1945, would have to:

• Designate a qualified and experienced person responsible for batch release.
• Maintain prescribed records for every batch manufactured.
• Follow a prescribed format for the Batch Release Certificate.

Batch release is a critical stage in pharmaceutical manufacturing. It involves reviewing quality parameters and relevant documentation before a batch is cleared for distribution.

The proposed requirements seek to establish clear accountability for batch-release decisions, improve traceability and strengthen quality assurance.

The World Health Organization (WHO) has reported significant global progress against neglected tropical diseases (NTDs), with fewer people requiring treatment. However, the rising burden of dengue remains a major concern.

The Global Report on Neglected Tropical Diseases 2026 found that 63 countries had eliminated at least one NTD by June 2026, up from 42 at the end of 2020.

“Elimination of neglected tropical diseases is one of the standout success stories of global health,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General.

However, he warned that these gains could be lost without increased domestic financing, sustained external support and the integration of NTD services into primary healthcare.

The number of people requiring interventions for NTDs fell to 1.41 billion in 2024, a 36% decline since 2010 and a 19% decline since 2020.

Cases of sleeping sickness have dropped by 98% since 1999, while Guinea worm disease recorded just 10 human cases in 2025, its lowest number yet.

Between 2021 and 2025, 31 countries eliminated at least one NTD. Of these, 16 received WHO recognition for the first time. Between January and June 2026, five more countries received recognition: Algeria, Australia, Libya and Tunisia for trachoma, and Chile for leprosy.

By June 2026, 42 countries had eliminated one disease each, 16 had eliminated two, four had eliminated three and one country, Togo, had eliminated four.

India has eliminated three NTDs: Guinea worm disease in 2000, yaws in 2016 and trachoma in 2024.

Why Dengue Remains A Concern

Despite progress against several NTDs, the report highlights uneven progress, with these diseases continuing to disproportionately affect the world's poorest and most vulnerable communities.

Dengue remains a major concern. Cases of the mosquito-borne disease reached a record 15.1 million in 2024, up from 2.74 million in 2020.

Locally acquired cases were reported across all six WHO regions. The organisation also classified dengue as a Grade 3 emergency, its highest emergency level, in 2024.

The Region of the Americas accounted for most reported cases, with Brazil contributing the largest share of the regional burden.

WHO said climate and environmental change, rapid and often unplanned urbanisation, population movement and the geographical expansion of Aedes mosquitoes are contributing to the spread of dengue.

WHO also warned that the geographical expansion of dengue into previously unaffected populations increases the risk of severe disease from secondary infections, making health system preparedness and the management of severe cases increasingly important.

In 2024, 12,554 deaths were reported across dengue, visceral leishmaniasis and chikungunya, against the 2030 target of 1,291 or fewer annual deaths.

Dengue accounted for 11,827 of these deaths, followed by visceral leishmaniasis (482) and chikungunya (245). Compared with the 2016 baseline of 5,163 deaths, reported deaths from these three diseases increased by 143.2%.

Other NTD Targets Remain Off Track

The report also identified several challenges to achieving the 2030 targets. Deaths from vector-borne NTDs have increased, while progress towards yaws eradication remains off track. Only three disease-specific indicators achieved their 2025 milestones.

The WHO's 2021–2030 road map aims to:

• Reduce by 90% the number of people requiring NTD interventions

• Reduce NTD-related disability and premature deaths by 75%.

• Enable 100 countries to eliminate at least one NTD

• Eradicate Guinea worm disease and yaws

With five years remaining to meet these targets, WHO called for accelerated action, increased domestic financing and the integration of NTD interventions into universal health coverage to protect progress and address persistent gaps.

Utah has become the first US state to authorise an artificial intelligence (AI) system to issue prescriptions for certain medications, marking a significant development in the use of AI in healthcare.

The pilot programme allows Nolla Health, a healthcare technology startup, to use its AI-powered dermatology app, Nolla Derm, to examine adults with mild-to-moderate acne and recommend prescription treatments without requiring an doctor's and supervision.

The programme is currently limited to adults aged 18 and above in Utah and covers a small list of topical acne medications. However, the initiative is significant as AI systems can eventually issue prescriptions without a doctors reviewing every case beforehand.

The development has also raised questions about whether AI can make decisions that are normally made by licensed medical professionals, especially when a prescription depends on assessing a patient's symptoms, medical history and treatment risks.

How Does Utah's AI Prescription Work?

Patients using Nolla Derm are required to verify their identity, provide informed consent and complete a medical questionnaire. They then submit photographs of their face through the app.

The AI system analyses the images to check acne severity and combines this information with the patient's medical history to determine whether treatment is appropriate.

It can then select from a limited list of topical acne treatments approved by physicians and generate a prescription.

The programme is being introduced in three stages, with different levels of medical supervision.

• First 100 patients: Two Utah-licensed physicians independently review and approve every AI-generated prescription before it is sent to a pharmacy.
• Next 400 patients: The AI can issue prescriptions directly and physicians will review cases retrospectively.
• Subsequent patients: Physicians review at least 10% of prescriptions each month, along with cases involving complications or side effects.

Advancing in stages requires the company to meet safety targets, including at least 95% agreement with physician assessments and no serious adverse events, as well as written approval from the state. Patients can also contact a licensed physician through the app.

Patient Safety Concerns

While AI can analyse information quickly, prescribing medication involves more than identifying a condition and selecting a drug. Doctors consider a patient's medical history, allergies, existing medications, and other health conditions. There are several concerns surrounding the use of AI for these decisions.

1. Incorrect diagnosis

An AI system assessing acne through photographs may not always be able to distinguish it from other skin conditions. Some skin disorders require different treatments or deeper medical investigation.

If the system incorrectly classifies a condition as acne, a patient could receive inappropriate medication, which could delay correct diagnosis.

2. Missing important medical details

A prescription may be unsuitable because of a patient's allergies, medical history, pregnancy status or other medications.

Although Nolla Derm collects medical information through a questionnaire, questions remain about whether an automated system can consistently identify important details.

3. Delayed treatment

Not every skin problem is acne. Some lesions or changes in the skin may require an examination to rule out other conditions, including skin cancer.

If patients rely on an automated assessment instead of seeking medical attention, there is a risk that a condition could be overlooked and its diagnosis could be delayed.

4. Limited ability to detect complications

Patients may experience side effects after starting treatment. An AI system may not be able to assess these developments as comprehensively as a clinician who can examine the patient, order investigations or modify treatment.

5. Accountability when something goes wrong

Another concern is determining who is responsible if an AI-generated prescription causes harm. The Utah pilot includes oversight and malpractice insurance requirements, but the bigger question of accountability remains an important issue.

The initiative has prompted concerns among medical professionals about how much responsibility AI systems should be given in healthcare. John Whyte, chief executive of the American Medical Association (AMA), has questioned whether AI should independently make medical decisions.

"These tools can play a very effective role, but they shouldn't autonomously be trying to practice medicine, and if they are, then they need to be held to very high standards, just as humans are," he told the Los Angeles Times. "And I don't think they can meet that burden," he added.

Earlier in 2026, Utah authorised another AI pilot involving prescription refills through the healthcare startup Doctronic. The programme attracted criticism from the state's Medical Licensing Board, which raised concerns about allowing AI to handle medication decisions without medical professionals.

Can AI Prescribing Improve Access To Healthcare?

Supporters argue that AI could help address gaps in access to medical care, especially for conditions that are commonly straightforward.

Zach Boyd, director of Utah's Office of Artificial Intelligence Policy, said the programme was designed to encourage healthcare innovation while maintaining safeguards.

"The Nolla Health pilot program represents a significant step forward in leveraging AI to improve healthcare access for Utahns, while maintaining rigorous oversight and safety," he said. "Our office facilitates innovative AI solutions while ensuring that public health and patient safety remain paramount."

Nolla's chief medical adviser, Dr Zaid Fadul, also highlighted the importance of independent oversight.

"The real test for AI in healthcare isn't how smart it is. It's whether someone other than the company can shut it off," he said.

"In Utah, the state can, and physicians can. That's the standard every AI in medicine should meet."
