Covid Variant XFG Spreading Fast: Which US States Are Most Affected?

20 August 2025

Rising Concerns Across the Country

A new Covid variant, known as XFG, is spreading quickly in the United States and has become a cause for concern among health experts. While still under study, early reports suggest that XFG has a higher transmission rate compared to earlier strains, raising alarms about potential surges in infections.

States Seeing the Biggest Impact

Certain states are reporting faster growth of XFG cases than others. California, Texas, Florida, and New York have shown a sharp increase, largely due to their high population density and international travel hubs. Midwestern states like Illinois and Michigan are also beginning to see notable clusters of cases.

Why Experts Are Worried

The XFG variant appears to spread more rapidly and may cause stronger flu-like symptoms, such as high fever, sore throat, body aches, and fatigue. Hospitals in several states have already reported rising admissions, which could strain healthcare systems if cases continue to climb.

Prevention Still Matters

Health officials emphasize that the best defense against XFG remains the same: vaccination, booster doses, mask-wearing in crowded places, and proper hygiene. Individuals with symptoms are advised to get tested quickly and isolate to prevent further spread.

Looking Ahead

As research continues, experts are monitoring whether XFG may lead to severe outcomes or affect vaccine effectiveness. For now, awareness and precaution remain key, especially in the states already seeing major outbreaks.
