Daily Covid cases at all-time record as hospitalizations hit 400 mark


In its weekly Covid-19 summary, the Delaware Division of Public Health reported a record number of daily cases as well as a growing number of new infections, hospitalizations, critical cases, and instances of the fast-spreading omicron variant.

DPH reported the highest number of new positive daily cases since the start of the pandemic with 1,393 positive cases as of Thursday. The previous record high was 1,241 on Jan 6 of this year.

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 six additional specimens sequenced at an outside lab. Out of the 280 variant positive samples, A total of 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 variants; it is not used to diagnose individuals with a specific strain, as treatment recommendations do not differ based on variant strains. Covid-19 tests identify current infections, but do not identify a specific variant of the virus the individual might have.
