Tracking variants allows us to see when a new variant has been detected and is increasing over time in the state. Early detection of a new variant could warrant the state shifting aspects of its response, and it may warrant individuals making more cautious choices.
The chart here shows the COVID-19 variants identified each week among specimens sequenced by laboratories that report whole genome sequencing (WGS) results to NCDHHS. The number of sequenced specimens shown is a small proportion of the total number of COVID-19 cases in North Carolina.
Whole genome sequencing (WGS) allows tracking of genetic changes in the SARS-CoV-2 virus, the virus that causes COVID-19. These genetic changes occur over time and lead to the emergence of new variants that may have different characteristics.
More detailed data is available from our weekly respiratory report, and the Centers for Disease Control.
