WHO Warns of New COVID-19 Variant (KP.3)
The World Health Organization (WHO) has issued a warning about the KP.3 variant, a new sublineage of Omicron, which is contributing to a rise in COVID-19 cases in the U.S. and Europe. Health officials are urging high-risk individuals to get updated boosters, as early data suggests this variant may be more transmissible than previous strains.
Key Details About KP.3
- Classification: A descendant of the JN.1 Omicron subvariant, part of the “FLiRT” mutations (F456L + R346T).
- Spread: Increasing in the U.S., now accounting for ~25% of new cases (CDC).
- Symptoms: Similar to other Omicron strains (fever, cough, fatigue), but severity varies.
- Vaccine Effectiveness: Early lab studies suggest updated 2023-2024 boosters provide some protection.
WHO & CDC Recommendations
- High-risk groups (elderly, immunocompromised) should get boosted.
- Monitor for symptoms and test if exposed.
- Improve ventilation in crowded spaces.
