About the Nomenclature System
What are Pango Lineages?
Pango lineages provide a systematic, hierarchical nomenclature for naming and tracking the genetic evolution of SARS-CoV-2, the virus that causes COVID-19. This naming system is essential for epidemiological tracking, public health responses, and vaccine development.

Hierarchical Naming
Lineages are named hierarchically (e.g., BA.2.86.1), clearly showing evolutionary relationships between variants.
Global Standard
The internationally recognized system used by WHO, public health agencies, researchers, and media worldwide.
Real-time Updates
Continuously updated as new variants emerge and are characterized by our international committee of experts.
Quality Assured
Every lineage designation undergoes rigorous review following strict epidemiological and phylogenetic criteria.
