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.

Whooping cough deaths are rising in the US, as the country sees a surge in the infection. So far, tens of thousands have been infected, with at least 13 people dead from the bacterial infection this year. While the infection rate is lower than last year it continues to remain above typical pre-pandemic years. The Scientific American reports that the number of deaths have also seen a rise.

What Causes Whooping Cough?

Whooping cough or what is scientifically known as the respiratory infection called pertussis is severe, and is characterized by violent cough. It could leave people, especially infants, struggling to breath. While it is rarely fatal, it can have lingering symptoms and thus have earned the name '100-day cough'. Whooping cough is caused by the bacterium Bordetella pertussis, which emits toxins into a person's respiratory tract. This is why early treatment with antibiotics vital to managing the infection. The bacterium is easily spread between people, through direct contact and droplets from mouth or nose. This is what makes it contagious.

According to the Centers for Disease Control and Prevention, the US and its territories recorded 27,871 confirmed cases of whooping cough as of December 20 this year. By the same point last year, cases had reached 41,922, marking a sharp rebound after four pandemic years when annual infections stayed below 10,000.

How Lethal Is Whooping Cough?

As of now, 13 people have died of pertussis this year. As per the report from the Pan American Health Organization, and provision CDC data from last year, 10 deaths were noted in 2024, while three increased in 2025.

Public health experts worry that persistently high whooping cough cases this year, following last year’s surge, may reflect falling vaccination rates. The DTaP vaccine protects infants and young children, while Tdap covers older children and adults. CDC guidelines recommend multiple doses starting at two months, yet only 79 percent of children born in 2021 had received four DTaP doses by age two.

Who All Can Get The Shot For Whooping Cough?

Whooping cough is most dangerous, especially among infants under a year old. Public health experts also recommended that pregnant people must get the Tdap vaccine to transfer the antibodies to newborns. All adults are also advised to get the Tdap vaccine in every 10 years to ensure a continued protection.

What Are The Common Symptoms Of Whooping Cough?

Early symptoms that can last for 1 to 2 weeks usually include:

• Runny or stuffed-up nose
• Low-grade fever (less than 100.4°F)
• Mild, occasional cough

CDC notes that later symptoms could be rapid, violent, and uncontrolled coughing fits. About one to two weeks after early symptoms begin, many people develop intense coughing spells, known as paroxysms. These fits typically last one to six weeks, but in some cases can continue for up to 10 weeks. As the illness progresses, the cough becomes more frequent and severe.

During these episodes, people may produce a high-pitched “whoop” when breathing in, vomit during or after coughing, feel extreme exhaustion, struggle to breathe, have trouble sleeping, or even fracture a rib. Many describe it as the worst cough they have ever experienced.

As 2025 ends, more and more people are falling ill. With a surge in flu cases, and mystery disease like adenovirus, thousands of people are already infected. Now, a deadly fungus, also considered a superbug due to its resistance to all types of antibiotics. This is Candida auris.

What Is Candida Auris? The Superbug Resisting All Antibiotics

It is a type of invasive year that can cause deadly infections in people, especially with weakened immune system. As of now, it has infected at least 7,000 people across 27 US states, confirmed the data from the Centers for Disease Control and Prevention (CDC).

The fungus can spread easily in healthcare settings, especially in hospitals and nursing homes. It is also spreading at an "alarming" rate, says CDC. The Hill reported that some strains of the fungus are troublesome because they are resistant to all types of antibiotics that are commonly used to treat fungal infections.

Due to fungus's resistance to antibiotics, it is becoming difficult to contain. As of now, more than half of the states have reported clinical cases of Candida auris in 2025. Another factor that makes it more dangerous is that standard lab tests cannot detect it. In a CDC press release, a CDC epidemiologist Dr Meghan Lyman said, "The rapid rise and geographic spread of cases is concerning and emphasizes the need for continued surveillance, expanded lab capacity, quicker diagnostic tests, and adherence to proven infection prevention and control."

Origins Of Candida Auris - The Superbug

This was first discovered in 2009 in Japan from the ear canal of a patient. Since then, it has spread to many countries, including India, where it was identified as a major public health threat in 2014.

Can Anyone Fight Off This Superbug?

Healthy people could possibly fight off this infection on their own. However, the population vulnerable could find it more difficult to fight off this deadly fungus. Melissa Nolan, an assistant professor of epidemiology and biostatistics at the University of South Carolina told Nexstar, "If you get infected with this pathogen that’s resistant to any treatment, there’s no treatment we can give you to help combat it. You’re all on your own."

Like the mystery disease, adenovirus, this fungus too can survive on surfaces, said Nolan. “It’s really good at just being, generally speaking, in the environment. So if you have it on a patient’s bed for example, on the railing, and you go to wipe everything down, if in whatever way maybe a couple of pathogens didn’t get cleared, then they’re becoming resistant. And so over time, they can kind of grow and populate in that hospital environment," said Nolan.

Is This Superbug Only Limited To The US?

Studies show that this superbug is not just limited to the US, but is spreading globally. It has already been found in at least 61 countries and on 6 continents. The study also found that the fungus is becoming more and more drug resistant, all due to its ability to switch from a yeast-like growth to a filament-driven spread. It also contains a cell wall that has proteins and makes it easier to stick on human skin "like glue". This is what enables it to colonize the human cells.

Former Australian batter Damien Martyn, 54, is suffering from meningitis, and was taken ill on Boxing Day in a Queensland hospital. The news on his condition came on Tuesday evening, and details confirmed to ESPNcircinfo noted that he is currently in an induced coma.

Former players, his colleagues and the sporting community is rallying around the 54-year-old, who currently "is in for the fight of his life" said the former AFL player Brad Hardie. His former teammate Darren Lehmann also told Martyn to "keep strong" on X.

“He is getting the best of treatment and [Martyn’s partner] Amanda and his family know that a lot of people are sending their prayers and best wishes,” said Adam Gilchrist his former Test and Western Australia teammate. Cricket Australia boss, Todd Greenberg, also wished Martyn a quick recovery. “I’m saddened to hear of Damien’s illness,” he said. “The best wishes of everyone at CA and in the wider cricket community are with him at this time.”

What Is Meningitis?

According to NHS UK, it is an infection of the protective membranes that surround the brain and spinal cord. It can affect anyone, but is most common in babies.

While fever is not always present, it is usually considered as one of the classic symptoms of meningitis. It is important to know the varied symptoms, causes, and treatments of meningitis for early diagnosis and proper management of the disease.

Meningitis is an infectious illness that brings about inflammation in the meninges. The most common cause of such inflammation is bacterial or viral infections, though other causes are also possible including fungal, parasitic, or non-infectious causes (autoimmune disease, head injury, or brain surgery). Meningitis may be caused by bacterial meningitis, which the Centers for Disease Control and Prevention (CDC) indicates can be so severe and bring about conditions like hearing loss, vision problems, and death if not received on time.

Does Meningitis Always Result in Fever?

Although fever is a common presentation of meningitis, it is not always present. Certain people, particularly those with compromised immune systems, newborns, or the elderly, can get meningitis without significant temperature elevation. In these instances, other signs such as headache, confusion, or stiff neck can be more suggestive symptoms of the disease.

Fever in meningitis is usually caused by the body's immune reaction to the infection, but some factors can affect its occurrence or absence, such as:

• The nature of meningitis (bacterial, viral, fungal, or non-infectious)
• The immune response of the individual
• Pre-existing health conditions
• The course of the disease

Identifying the Symptoms of Meningitis

Meningitis signs may differ based on the reason and severity of infection. Even though fever is a common symptom, it should also be noted for other vital symptoms, which are:

• Severe headache
• Stiff neck
• Photophobia (sensitivity to light)
• Nausea and vomiting
• Confusion or inability to concentrate
• Fatigue or trouble waking up
• Seizures
• Skin rash (in meningococcal meningitis)

Symptoms in infants can be different and also involve excessive crying, irritability, feeding problems, a bulging soft spot (fontanelle) on the head, and unusual lethargy.
