COVID-19 is making a comeback in several parts of the world, with new variants like XFG, NB.1.8.1, and LF.7 driving a fresh wave of infections. Health experts are monitoring the spread closely to assess if these strains pose a bigger risk than their predecessors.
What Are These New Variants?
-
XFG Variant: Recently detected in parts of Asia and Europe, this strain appears to spread faster than previous Omicron subvariants.
-
NB.1.8.1: First identified in the U.S., it shows a high mutation count in the spike protein.
-
LF.7: A fast-spreading variant found in community clusters, under study for immune escape potential.
Are These Variants More Transmissible?
According to virologists, preliminary data suggests that these strains may be more contagious, but not necessarily more deadly. The XFG and LF.7 variants show signs of higher airborne spread, especially in enclosed spaces.
Early Symptoms to Watch For
Patients infected with these variants are reporting symptoms similar to Omicron, but with some mild differences:
-
Runny nose 🤧
-
Sore throat 🔥
-
Mild fever 🌡️
-
Dry cough
-
Headache
-
Fatigue
-
Occasional body aches
In some cases, NB.1.8.1 has shown longer-lasting fatigue and throat irritation.
How Severe Are These Infections?
While hospitalization rates remain low, elderly and immunocompromised patients should stay alert. So far, there’s no evidence of increased severity, but researchers are still collecting data.
Should You Be Worried?
Health authorities recommend staying up-to-date on boosters, especially for high-risk groups. Masking in crowded indoor spaces and maintaining basic hygiene is again being advised in affected regions.
Countries Reporting a Surge

🇮🇳 India (states like Kerala, Maharashtra)
-
🇺🇸 United States (California, Texas)
-
🇬🇧 UK (isolated clusters)
-
🇨🇳 China (limited but monitored spread)
Scientists Say…
According to the WHO and CDC, mutation monitoring is ongoing, and current vaccines still offer protection against severe illness from these variants.
