As of 23/05/2022, the Sanger Institute has sequenced 2,176,743* coronavirus genomes. All are freely available for analysis via ENA and GISAID**. Across the globe, there are a total of 10,975,766** sequences available.
At the Sanger Institute, we have received and handled more than 27 million samples since March 2020. These samples are the residues of PCR tests, which test for the presence of the virus.
We receive up to 200,000 samples a week and currently sequence about 60,000 per week. These 60,000 are chosen using an algorithm, agreed with UKHSA, which ensures geographic coverage and priority samples are sequenced.
Capacity is being increased to be able to sequence 64,000 per week.
The genome data are analysed by scientists at the Sanger Institute, UKHSA and beyond. The genome sequence determines which variant of the virus is present.
We do not hold or have any access to anyone’s personal information.
