Researchers at Karolinska Institutet in Sweden have developed a technology for cost-effective surveillance of the global spread of new SARS-CoV-2 variants. (SARS-CoV-2 is the virus that causes COVID-19.) The technique is presented in the scientific journal Nature Communications.

Since the onset of the COVID-19 pandemic, thousands of viral genomes have been sequenced to reconstruct the evolution and global spread of the coronavirus. This is important for the identification of particularly concerning variants that are more contagious, pathogenic, or resistant to the existing vaccines.

For global surveillance of the SARS-CoV-2 genome, it is crucial to sequence and analyze many samples in a cost-effective way. Therefore, researchers in the Bienko-Crosetto laboratory at Karolinska Institutet and Science for…
