Doctors disclose uncommon symptoms of new Covid variants 'Stratus' and 'Nimbus' spreading across the US

Two new Covid variants are currently spreading across the US

Two new Covid variants are spreading across the country, presenting some unusual symptoms.

The strains, XFV, known as Stratus, and NB.1.81, called Nimbus, are causing a surge in infections across the US, with medics issuing a strong warning that even mild cases could lead to long-lasting effects.

Infections have notably increased in the northeast region at the end of August, reaching a peak in mid-September.

According to the CDC, nationwide Covid wastewater levels, which help measure the community spread of the infection, are at a 'moderate' level, though it notes that at least four US states have 'very high' levels.

The new variants are also putting vulnerable groups at risk, particularly older adults and individuals with underlying health conditions or compromised immune systems.

While these cases are known to cause typical Covid symptoms—such as headaches, fatigue, coughing, and a runny or blocked nose, similar to the flu—doctors are also cautioning about the unusual symptoms these variants are causing in patients and the rapid spread.

Doctor Aaron Glatt, an infectious disease specialist at Mount Sinai Hospital in New York, mentioned to Today.com that 'severe pain' is a common issue, with patients experiencing sensations 'as if their throat is covered with razor blades.'

He noted: "Although not exclusive to Covid-19, this description has been used to characterize sore throat symptoms in some patients with the latest Covid-19 variant."

Others are also expressing concern about declining Covid vaccination rates potentially contributing to a rise in cases, as a CDC panel decided against recommending the shots for 'individual decision-making'.

Meanwhile, an infectious disease expert, who served as New York City's chief medical officer during the initial pandemic wave, cautions that Coronavirus is 'clearly on the rise again'.

Doctor Tyler Evans told The Daily Mail: "While we’re in a much better situation than in 2020, increasing transmission still poses a threat to those with underlying conditions or limited access to care. Concern should lead to preparedness, but not panic."

He stated: "The prevalent strain in the US at the moment is an Omicron subvariant known as Nimbus (NB.1.8.1). It spreads rapidly but is not more severe than previous variants."

Although it is not more dangerous than earlier strains, Dr. Evans mentioned that it 'can still pose a risk for older adults, individuals with chronic conditions, and those with compromised immune systems.'

Dr. Laura Malone, director of the Pediatric Post-Covid-19 Rehabilitation Clinic at Kennedy Krieger Institute in Baltimore, informed the New York Times that even mild infections can have long-term effects, such as long Covid.

"Just because you got through your first infection without developing long Covid, it doesn’t mean you are completely in the clear," she clarified.

On a positive note, Covid wastewater levels are showing signs of decreasing, with a decline observed in the week of September 13. However, Nevada, Connecticut, Utah, and Delaware are currently experiencing 'very high' levels.
