COVID-19 Variant Cases in Delaware:  

During the week of Dec. 16 – Dec. 22, a total of 416 test samples were sequenced through routine surveillance of test specimens. Of those test samples, 274 (65.9%) sequenced at the DPH Lab were positive for a variant strain, as were 6 additional specimens sequenced at an outside lab. Out of the 280 variant positive samples, 247 were identified as the Delta strain, and 33 were identified as the Omicron strain. To date, a total of 37 cases of the Omicron variant have been identified in Delaware.

The Delaware Public Health Laboratory and other laboratories regularly monitor for the presence of COVID-19 variants, including Delta and Omicron, through routine genomic sequencing of test specimens. Genome sequencing is a public health surveillance tool used to monitor the prevalence of COVID-19 variants; it is not used to diagnose individuals with a specific strain of COVID-19, as treatment recommendations do not differ based on variant strains. COVID-19 tests identify current infection of COVID-19, but do not identify a specific variant of the virus the individual might have.
