The Delta variant of the SARS-CoV-2 virus has become the dominant strain in California. Last week, 634 cases were detected in the state, while the total as of Thursday was 1,085, representing an increase of 71 percent in just a few days.
However, the numbers could be much higher given that only a fraction of COVID-19 tests are genetically sequenced, a process that determines whether positive cases belong to any variant.
