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.

GLP-1 weight-loss drugs have taken the world by storm. One new entrant is Eli Lilly's retatrutide, which has demonstrated bariatric surgery-level weight loss.

Retatrutide is not yet FDA-approved or commercially available; it is expected to be available by the end of 2026.

According to a media report, Eli Lilly and the Food and Drug Administration (FDA) have allowed one person to gain access to the drug through the company's "compassionate use" program. It is generally used by patients with serious and immediately life-threatening medical issues to get access to experimental treatments.

STAT News, citing sources, reported that a request for drug access was made in April for a 79-year-old, well-connected man, and indicated that the person could be US President Donald Trump, who turned 80 a week ago.

What Did White House Say

The White House has aggressively denied the claim.

"This application was not for the President," said, White House spokesperson Kush Desai, while blasting STAT on X..

STAT claimed that "during the Covid-19 pandemic, Trump was notably one of the first people administered an antibody treatment from Regeneron after he contracted the virus, via this same compassionate use pathway".

Further, the media outlet cited that Ranganath Muniyappa, a senior clinician at the National Institutes of Health, had requested the drug to treat a patient for refractory obesity with obstructive sleep apnea and pulmonary hypertension, noting it inquired whether Trump has those conditions.

In response, Desai referred to a White House memo on Trump's most recent medical evaluation that did not contain any mention of obstructive sleep apnea or pulmonary hypertension.

Did Trump take Ozempic?

Earlier this year, Trump told The New York Times that he had not taken GLP-1 drugs like Wegovy and Ozempic but said, "I probably should."

Notably, Trump's latest physical exam revealed the president weighed 238 pounds, a 14-pound increase from April 2025 that nearly reached the threshold of clinical obesity.

Trump's health has been under increased scrutiny as he turned 80 this year and has been frequently seen with swollen ankles and bruises on his hands.

Retatrutide is similar to drugs like Zepbound and Wegovy that mimic the GLP-1 hormone. The drug aims to maximize weight-loss results with fewer side effects for users. If approved, it could be helpful for patients who are struggling to lose weight on the current versions of GLP-1 drugs.

Unlike Zepbound, which is a double agonist, retatrutide, mimics glucagon along with GLP-1. It thus, works like a triple agonist.

In the third phase of clinical trial, the drug helped people lose up to 30 per cent of their body weight, which is about 85 pounds. The results are on a par with bariatric surgery, which helps people shed approximately 25 to 35 per cent of their total body weight within one to two years. Doctors say that this is the largest weight loss ever witnessed in a medical trial.

Dr Shauna Levy, medical director of the Tulane Weight Loss Center, explained that the current GLP-1s are not good enough to induce weight loss in people dealing with severe obesity and those who have a BMI of 35. Bariatric surgery can provide the same, but it seems that Retatrutide will be far more effective for people living with a high BMI who are trying to achieve a healthy weight.

Health officials in Australia have confirmed a third case of the deadly H5 bird flu in a migratory bird on Australia's southern coast, taking the total number of cases to three. The first two cases were reported in Western Australia.

The third case of avian influenza was recorded in a giant petrel found at Knights Beach on the Fleurieu Peninsula.

According to South Australian Premier Peter Malinauskas, the state recorded two sick birds that came into the care of a local wildlife rescue group on June 14, ABC News reported.

"Once that was drawn to the attention on June 19 to the relevant authorities in South Australia, we responded quickly and enabled and facilitated active testing of those birds for H5 bird flu," the premier said.

"This afternoon we received those results and they confirmed that one of those birds was negative and one of them was positive."

He also stressed the cases have no connection, as it involved a migratory bird.

"It's also important to emphasize that this is a migratory bird. This is not a contamination or infection that has come from WA to SA."

Further, Malinauskas noted that the volunteers who handled the birds would be given anti-viral medication if necessary.

He urged people who see unwell or dead birdlife to "avoid, record and report" via hotline 1800 675 888.

Malinauskas said two other sick birds found at Fowlers Bay yesterday had tested negative for the virus.

It comes after two birds were confirmed to have the disease near the town of Esperance in Western Australia.

The country's Chief Veterinary Officer, Dr Beth Cookson, said there was no indication it had spread from those two birds.

Genomic sequencing shows the virus in that initial bird — a brown skua — is related to an outbreak on Heard Island and McDonald Islands.

Why Australia Had Remained Bird Flu-Free

Until now, Australia was the only continent where the H5N1 strain, the highly contagious strain of H5 bird flu, had not been detected. Although the virus has circulated across Asia since the 1990s and reached Antarctica in 2024, Australia had remained unaffected.

According to Dr Michelle Wille, ARC Future Fellow at the University of Melbourne, Australia's unique bird migration patterns likely delayed the virus's arrival.

"There are no duck species which routinely migrate between Australia and Asia, nor are there ducks that migrate through Antarctica," Wille wrote in The Conversation.

However, evidence suggests other seabirds—including gulls, skuas and giant petrels—may have helped carry the virus over long distances across Antarctica and subantarctic regions, eventually bringing it closer to Australia, he said.

As per the latest update, Australian scientists believe that the H5 bird flu strain killed more than 13,000 elephant seal pups after infecting a breeding colony on the remote Heard and McDonald Islands, one of Australia's external territories in the sub-Antarctic.

Can Bird Flu Affect Humans?

Despite the rise in cases, Agricultural Minister Julie Collins assured the public that there is no immediate threat to human health.

"Chicken meat and eggs remain safe for consumption when properly prepared," she noted.

While human infections remain rare, they can occur through direct and unprotected contact with infected birds, animals, or contaminated environments.

Although severe human cases have historically shown a mortality rate of around 50%, sustained human-to-human transmission has not been observed.

How to Protect Yourself

Health authorities recommend the following precautions:

• Avoid direct contact with sick or dead wild birds and other animals whenever possible.
• Observe wildlife from a safe distance.
• Wear appropriate personal protective equipment (PPE) if handling sick or dead birds or animals is unavoidable.
• Avoid touching surfaces contaminated with bird droppings, saliva, mucus, litter, or bedding from infected or suspected animals.
• Do not consume raw milk or raw milk products, particularly from animals suspected or confirmed to be infected with avian influenza.
• Report sick or dead birds to local authorities if encountered.

French health officials have confirmed the first positive Ebola case in a doctor returning from a humanitarian mission in Congo.

It is the country's first case of the virus during the current outbreak, and the first in Europe. It is also the first case outside Africa in the 2026 outbreak.

The health ministry "confirms today the identification of a first positive case of Ebola virus disease on national territory", it said.

The patient, identified in mainland France, is being isolated and authorities are conducting contact tracing, the ministry said, adding that the risk to the general European population was low, AFP reported.

The confirmed cases in the Ebola outbreak in the Democratic Republic of Congo have reached the highest total ever recorded during the first month of an outbreak in Africa, according to the World Health Organization (WHO).

As of June 22, confirmed Ebola cases in Congo had risen to 1,094 and deaths to 277, according to the DRC Ministry of Health. The WHO raised concerns about the rapid spread of the deadly virus and the challenges facing containment efforts.

“This is the largest number of confirmed cases in the first month of an Ebola disease outbreak in Africa,” said Dr Abdirahman Mahamud, Director, Health Emergency Alert and Response Operations at WHO, during a press briefing in Geneva.

"What is important is we need to scale up and this outbreak is moving faster than us," he told reporters after returning from Bunia last week.

Mahamud also noted signs of hope, highlighting a quick increase in the number of Ebola beds to over 500 in the past fortnight and signs that community resistance and violent resistance to Ebola responders was beginning to abate.

Taking to social media platform X, Dr Tedros shared that “100 patients have recovered so far, which shows that for many, the virus can be stopped with timely health care”.

He also lauded efforts being made to “increase the number of Ebola Treatment Centres and lab and surveillance capacities, to train more health workers on clinical care and infection prevention and control, and to improve the understanding and involvement of communities”.

However, he highlighted the need to do more.

"More treatment centers, more trained health and care workers, more testing, more teams from within communities supporting communities. We need sustained and safe access to reach all affected people”.

US Supports Experimental Treatment Trials

Meanwhile, the US has provided doses of an experimental antibody drug from Mapp Biopharmaceutical for use in clinical trials to fight the widening Ebola outbreak in Congo, a Department of Health and Human Services spokesperson said, a shift from its position of making the drug available only to Americans, Reuters reported.

While the spokesperson declined to comment on the number of doses, it said that the drug is being made available for compassionate use in Congo as well as to advance a clinical trial in the outbreak region.

There are currently no approved vaccines or treatments for the Bundibugyo strain of Ebola.

This marks the first time the US government has indicated it plans to directly support clinical trials of the antibody treatment known as MBP134 from San Diego-based Mapp by providing stockpiled doses.

The Mapp drug is expected to be among the first treatments to be tested in the outbreak.

Trials of the Mapp drug and two Gilead Sciences antivirals are due to begin in the coming weeks, according to the WHO and scientists involved in the testing, the report said.
