A new Covid-19 wave is rising across the United States. The surge is fueled by the highly transmissible Stratus variant. National test positivity rates have climbed to 9.9 percent.
This marks a significant 1.4 percent increase from the previous week. Health officials are monitoring the situation closely as cases spread.
CDC Data Shows Southern States Hit Hardest
The Centers for Disease Control and Prevention (CDC) is tracking the spread. Their latest data shows a sharp rise in infections, particularly in the South. Some states in that region are reporting test positivity rates as high as 15 percent.
According to the CDC, the Stratus variant is now the most prevalent lineage. It is also known as XFG. The variant is dominant in both clinical specimens and wastewater surveillance data.
This suggests widespread community transmission. The World Health Organization has classified Stratus as a “variant under monitoring.” This means it is being watched for potential increased risk.
Understanding the Stratus Variant and Its Symptoms
The Stratus variant is an offshoot of the Omicron lineage. Researchers believe it emerged from a recombination of earlier strains. This has given it mutations that enhance its ability to spread.
Common symptoms remain consistent with recent variants. They include congestion, cough, fatigue, and headache. Some patients also report a mild fever and muscle aches.
There have been anecdotal reports of a severe sore throat, nicknamed “razor blade throat.” However, health experts caution against overstating this. A CDC spokesperson confirmed there is no data indicating Stratus causes more severe illness or unique symptoms.
Scott Roberts, an infectious disease expert at Yale, echoed this to Newsweek. He noted the symptom reports are likely anecdotal and not evidence-based. The CDC continues to recommend vaccination as the best defense.
The recent data confirms the virus is still evolving. The Stratus variant demonstrates the need for continued vigilance and updated protections.
Info at your fingertips
What is the Stratus Covid variant?
The Stratus variant, also called XFG, is a sublineage of Omicron. It emerged from a combination of earlier variants and is noted for its high transmissibility.
Are Stratus variant symptoms different?
No. The CDC states symptoms are similar to other recent variants. These include cough, congestion, fatigue, and headache. There is no evidence of more severe illness.
Which US regions are most affected?
Southern states are experiencing the sharpest rise in cases. CDC data shows test positivity rates in some areas have reached 15 percent.
Is the Stratus variant a concern?
The WHO lists it as a “variant under monitoring.” This means it is being watched but is not currently classified as a high-risk variant.
How can people protect themselves?
Health officials recommend staying up-to-date with Covid-19 vaccinations. Good hygiene practices and staying home when sick also help reduce spread.
