This is the first week the total of affiliated cases is higher. Almost all of these cases are due to the delta variant, as has been the case for most of the summer. TGen’s COVID sequencing dashboard lists delta as being responsible for 98.89% of genomes sequenced in Arizona in September and 97.2% of genomes in August. The county report lists a total of 796 delta cases over the course of the pandemic so far. “Delta won,” said David Engelthaler, director of TGen North.
