There are two new Covid variants emerging across the United States, presenting with some distinct symptoms not previously seen. The variants, known as XFV or Stratus, and NB.1.81, referred to as Nimbus, are contributing to a rise in cases. Health professionals caution that even mild infections might lead to persistent consequences.
These variants have particularly affected the northeastern US, with cases climbing significantly from late August to mid-September.
The Centers for Disease Control and Prevention (CDC) reports that Covid wastewater levels, an indicator of community transmission, are at a ‘moderate’ level nationally. However, four states are experiencing ‘very high’ levels.
The newly identified strains are particularly concerning for individuals with heightened susceptibility, such as older people and those with pre-existing health issues or compromised immune systems.
Traditional Covid symptoms, such as headaches, fatigue, coughing, and nasal congestion, are present, but medical professionals are also noting unusual symptoms and rapid spread associated with these variants.
Dr. Aaron Glatt, an infectious disease authority at Mount Sinai Hospital in New York, shared with Today.com that patients are experiencing ‘severe pain’, describing their sore throats as feeling ‘as if their throat is covered with razor blades.’
He noted, “While not specific to Covid-19, this expression has been used to describe sore throat symptoms in some patients with the most recent Covid-19 variant.”
Experts are also highlighting concerns about declining vaccination rates, which may contribute to the increase in cases, following a CDC panel’s decision against recommending universal Covid shots.
Nevertheless, an infectious disease expert who was New York City’s chief medical officer during the pandemic’s first wave warns that Covid-19 is ‘clearly on the rise again’.
Dr. Tyler Evans explained to The Daily Mail, “While we’re in a much better place than in 2020, rising transmission still poses a risk to those with underlying conditions or limited access to care. Concern should lead to preparedness, but not panic.”
He added, “The dominant strain in the US right now is an Omicron subvariant called Nimbus (NB.1.8.1). It spreads quickly but is not more severe than earlier forms.”
Although not more severe, Dr. Evans pointed out that it ‘can still be dangerous for older adults, people with chronic conditions, and those with weakened 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 cases could result in long-term issues like long Covid.
“Just because you got through your first infection and didn’t develop long Covid, it’s not that you are completely out of the woods,” she stated.
On a positive note, Covid wastewater levels appear to be decreasing, with a drop observed in the week of September 13, although Nevada, Connecticut, Utah, and Delaware are still reporting ‘very high’ levels.
