Mysterious “chemical fog” sparks health concerns and conspiracy theories across the U.S.

 A mysterious fog with a distinct "chemical smell" has swept across multiple states, leaving Americans alarmed and sparking a wave of concern. Residents from Texas to Florida and beyond have reported flu-like symptoms after brief exposure to the fog, which has been described as unusually dense and lingering. While experts attribute the phenomenon to natural weather patterns and seasonal pollutants, social media users are speculating about everything from bioweapons to government experiments.

The fog first appeared in late December, with reports emerging from states including Texas, Wisconsin, Iowa, Maryland, Virginia, West Virginia, Nebraska, Kansas, Oklahoma, North Dakota, Florida and Minnesota. Locals have taken to social media to share videos and testimonials, describing symptoms such as coughing, sore throats, congestion, eye irritation, lethargy and stomach cramps.

One Florida resident told DailyMail.com that she felt ill after just 10 minutes outside. "Within about an hour, I kept sneezing over and over for about three hours, and my eyes were really puffy," she said. "I got very warm and I felt like I had a fever, and my stomach was cramping." Similar accounts have flooded platforms like TikTok, where users like "Rusky" from the Pacific Northwest described symptoms including a sore throat, coughing and fatigue.

The fog’s unusual characteristics – its chemical odor, lingering presence and visible "white particles" – have fueled speculation. Some residents have even checked their air filters, only to find them clogged with residue. A North Dakota resident shared a video comparing a recently changed filter to one covered in grime, warning others to "beware the fog."

David Bamber, a resident of St. Petersburg, Florida, posted a TikTok video walking through the dense fog. He noted that while normal fog dissipates, this fog lingers late into the night. "The weirdest part is the taste and smell," he said. "It smells like after you set off a bunch of fireworks, and the taste of the air is toxic. It is super weird."...<<<Read More>>>...
