Genomic sequencing is crucial in the battle against coronavirus. These countries do it well

CNN  

CNN — When South African scientists announced they had detected a new coronavirus variant with a worryingly high number of mutations, they were applauded for how quickly they were able to spot it. Sequencing efforts around the world leave much room for improvement, but South Africa’s discovery of the Omicron variant is an example of how focused efforts can make a big difference. “ highlights the continued importance and need for genomic surveillance of SARS-CoV-2 and access to relevant samples to do this,” Sharon Peacock, a professor of Public Health and Microbiology at the University of Cambridge, said, adding that the South African Health Ministry and its scientists “are to be applauded in their response, their science, and in sounding the alarm to the world.” In the past 30 days – during which time Omicron came to the global spotlight – fewer than a third of countries and territories sequenced cases to identify how the virus has changed over time, according to CNN analysis of data reported to the global science initiative GISAID. In the past month, when the Omicron variant became the latest variant of concern, only a dozen countries conducted sequencing for more than 5% of their Covid-19 cases.
