New COVID Variant Spreads Rapidly U.S: As the world breathes a cautious sigh of relief post-pandemic, a new twist in the COVID-19 story is capturing global attention. The XFG variant, nicknamed “Stratus,” is making waves, with cases spiking worldwide. First identified in Southeast Asia in January 2025, this cunning strain is now a focal point for health experts. Here’s a deep dive into Stratus, its symptoms, key dates, precautions, and answers to your burning questions, crafted to keep you informed and prepared.
What are the symptoms of Stratus?
The Stratus variant, officially labeled XFG by the World Health Organization (WHO), emerged in January 2025 in Southeast Asia. By June 2025, it had spread to 38 countries, prompting the WHO to designate it a “SATS-CoV-2 variant under monitoring.”
In the U.S., the Centers for Disease Control and Prevention (CDC) reported a surge in cases across nine states, New York, New Jersey, Delaware, Vermont, Michigan, Wisconsin, Minnesota, North Dakota, and South Dakota, based on wastewater monitoring data from the week of September 15, 2025. This data confirmed Stratus as the predominant variant in the U.S., signaling its rapid rise.
Symptoms of the Stratus Variant
Stratus presents symptoms similar to earlier COVID-19 strains, though vaccinated individuals typically experience milder cases. Common symptoms include:
- Fatigue
- Fever
- Persistent, dry cough
- Shortness of breath
- Chest tightness
- Sore or scratchy throat
- Headaches and body aches
- Upset stomach or nausea
- Brain fog
- Loss of taste or smell
If you notice these symptoms, experts recommend seeking medical advice promptly. Treatment options include antiviral medications, over-the-counter drugs, or at-home remedies. Seek immediate care if you experience a high fever (over 103°F) lasting more than three days or if symptoms worsen after initial improvement.

What Makes Stratus Unique
Stratus follows the highly infectious Nimbus variant, which was notorious for causing severe “razor blade” sore throat symptoms, according to Stony Brook Medicine at Stony Brook University in New York. Unlike its predecessor, Stratus has evolved with mutations that enhance its ability to evade the immune system, making it more challenging to fight, particularly for the unvaccinated or those never infected, per WHO and Stony Brook Medicine reports.
