Weekly Covid update: New cases, hospitalizations show modest decline


The weekly report from the Delaware Division of Public Health shows a gradual decline in new Covid-19 cases as the number of vaccinations increase.

The seven-day average of new positive cases fell to  391.6 from  445.7 last week.

However, the virus remains persistent, with a weekly average of total positive tests at 8.2%, increasing 7.8% a week earlier. 

Hospitalizations totaled  207, a decrease of 27 from last week. The number of people in critical condition was 30, a decrease of two from last week.. 

Total Covid-19 deaths since last week totaled  24, including seven from a review of vital statistics records. Typically about three-fourths of those who die from complications from the virus are unvaccinated.

Of the 24 deaths, 16 were reported on Friday, including eight from a hospital system backlog, seven from a review of Vital Statistics records, and one recent death.

Of those who died, seven each were residents of Sussex and Kent counties, with two from New Castle County. They ranged in age from their 50s to their 90s. All had underlying health conditions and two were residents of long-term care facilities. Twelve were not vaccinated and four were fully vaccinated.

Covid-19 vaccinations 

  • Total number of doses administered in Delaware: 1,216,916
  • Percentage of Delawareans 12+ who have received at least one dose (CDC data): 78.5%
  • Percentage of Delawareans 18+ who received at least one dose (CDC data): 80.2%
  • Delawareans who are fully vaccinated – 524,838, or about 53% of the state’s population based on the 2020 Census.  The number of fully vaccinated residents decreased due to an error that added in recently approved booster doses of Pfizer vaccine for the elderly and those with underlying conditions. Moderna and Johnson & Johnson booster shots are expected to be approved shortly.

Covid-19 variant cases

In the past week, 368 test samples were sequenced through routine surveillance of test specimens. Of those test samples, 246 (66.8%) sequenced at the DPH Lab were positive for a variant strain, as were eight additional specimens sequenced at an outside lab. Out of the 254 variant positive samples, all but one was identified as the Delta strain.

The Centers for Disease Control and Prevention (CDC) recently updated the classifications of known Covid-19 variants. Currently, the Delta variant is the only variant being monitored by the CDC as a “variant of concern,” and no other variants are presently classified as “variants of interest.” For more information regarding CDC variant classifications, visit https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/variant-surveillance/variant-info.html.
