XFG Variant Drives Rising Covid Activity Across U.S.
A new Covid variant, known as XFG or Stratus, has been steadily gaining ground in the United States since it was first detected in March. Health experts have been monitoring its spread closely as it begins to shape current infection trends.
According to the Centers for Disease Control and Prevention (CDC), national wastewater surveillance has shown a notable rise in viral activity. As of the week of September 7, the overall Covid activity level was classified as high, up from moderate just one week earlier.
The increase in cases is largely linked to the spread of the XFG variant. Early research suggests that XFG may be more contagious than earlier strains, a factor that helps explain its rapid dominance.
