SARS-CoV-2-Variants

This project tries to give a glimpse of the different variants of SAR-CoV-2 in the world.

Website: https://3dgiordano.github.io/SARS-CoV-2-Variants/

Naming:

The naming system used is a mix between the names denominated by WHO, the Pango Lineage system and some Nextstrain Clade names.

The project use the denomination of:

• WHO/CDC/ECDC/PHE Variants of Concern (VOC)
• WHO/CDC/ECDC Variants of Interest (VOI)
• WHO Alerts for Further Monitoring (AFM)
• CDC Variants Being Monitored (VBM)
• ECDC Variants Under Monitoring (VUM)
• PHE Variants Under Investigation (VUI)

If a major variant is detected, the WHO name is used. If it is some other variant to consider not yet considered by WHO, its Pango lineage is used. Otherwise, the first letters of the Pango lineage are used. If the variant is in WHO/CDC/ECDC VOI, VOC, AFM or VUM, the label is included.

About:

The project, site, published data, and graphics are free and open source. A work in progress project created by @3dgiordano. They can access the source code and data in their GitHub project https://github.com/3dgiordano/SARS-CoV-2-Variants.

Inspiration ideas

If it inspires, it is worth not to miss the opportunity to cite the people and their work.

Charts

The visualization idea is inspired by the work of Emma B. Hodcroft @hodcroftlab

Color scheme

The color palette was mainly based on the color palette used by the project Our World in Data Grapher
