XFG Variant Drives Rising COVID Activity Across U.S.

A new COVID-19 variant, called XFG or “Stratus,” has been steadily spreading across the United States since it was first detected in March. Health officials, including the CDC, have noted a sharp rise in viral activity, with national wastewater data showing COVID levels moving from moderate to high as of early September.

The rapid spread is largely attributed to XFG’s increased transmissibility. Early studies suggest the variant has mutations in its spike protein that allow it to partially evade immune responses from past infections or vaccinations. This gives it a greater ability to infect people, even those previously protected.

Despite its higher infection rate, experts emphasize that XFG does not appear to be more deadly than earlier strains. However, its speed of transmission raises concerns, especially for vulnerable populations such as seniors, the immunocompromised, and the unvaccinated. Healthcare facilities are being advised to prepare for a possible rise in hospitalizations in the coming weeks.

In response, public health officials continue to recommend preventive measures. These include receiving updated vaccines, improving indoor ventilation, and wearing masks in crowded or high-risk settings. Such actions remain effective in reducing transmission and protecting at-risk individuals.

The emergence of the XFG variant highlights the ongoing evolution of the coronavirus. While it may not cause more severe illness, its ability to spread faster underscores the importance of staying vigilant and responsive to new developments in the pandemic.
