VEO submits the seventh report on mutations and variation in publicly shared SARS-CoV-2 raw sequencing data.

In its seventh report to the European Commission, VEO Consortium members summarize mobilisation and analysis of SARS-CoV-2 sequence data submitted to the European COVID-19 Data Platform in the context of the VEO project, which aims to develop tools and data analytics for pandemic and outbreak preparedness.

Summary: 

  • Update on mobilisation of raw reads, now totaling sequencing data sets from 1,056,105 viral raw read sets from 69 countries, a 21% increase since the previous report.
  • The variant nomenclature has been updated, and tables on countries depositing data on VOC and VOI have been included.
  • The variant calling workflow for the Oxford Nanopore data has been implemented and 71,797 samples of the total 123,021 have been processed so far.
  • A new variant was named by WHO, designated Mu (Pango lineage B.1621). In regions with high prevalence of Delta variant, this virus does not seem to increase in prevalence, but it was put under increased surveillance because of dissemination in some countries, particularly in South America.
