Why track SARS-CoV-2 variants?
- To understand which strains are spreading in our state and make up the largest proportion of new cases.
- Variants can be more infectious and spread more quickly than the original strain. The Centers for Disease Control and Prevention (CDC) classifies these as variants of concern.
- To understand how common the new strains are in our communities, not to have a real-time number of cases that are tied to each strain.
