Variants arising all over the world

Learn about systems used to map and track coronavirus variants around the world.

With genomic surveillance networks hard at work within their own countries, the world is able to unite their data so that global movements in the pandemic can be understood.

In this video, you will see variants tracked from the beginning of the pandemic until the end of December 2021. This video was made using Nextstrain – an open-source project to harness the scientific and public health potential of pathogen genome data. NextStrain uses data aggregated by GISAID. GISAID is a non-profit organisation that encourages rapid data sharing for influenza and coronaviruses. GISAID was formed in response to the influenza outbreaks in 2006, and years later has proven to be critical for responding to coronaviruses causing COVID-19.

Can you spot certain variants appearing in your country? Have any variants shocked you in their speed or spread? Add your thoughts in the comment section

You can use the Nextstrain website to set your own timelines or specific criteria, give it a try if you like!
