“Case investigation and contact tracing to identify, inform and monitor anyone who was in close contact with these individuals is ongoing.,” Said Jen Brestel, a spokeswoman for the Delaware Division of Public Health.

SMYRNA (DE) BY DIGITAL STAFF: Following the Thanksgiving holiday, it’s no shock we are seeing an increase of COVID-19 cases in Delaware and we are not alone. States all across the country have been reporting an uptick in positive cases of COVID-19, and in the midst of all that Turkey, the Omicron variant have been on officials radar. 

It’s worrisome as Delaware hospitals have reached full capacity and in the midst of all chaos, The Delaware Division of Public Health (DPH) announced Friday December 17, 2021, that it has confirmed the first four cases of the Omicron variant (B.1.1.529) among Delaware residents. The variant was detected through routine sequencing of test specimens by the Delaware Public Health Laboratory.

According to officials, the four cases involve two adults in their 30s, a teenager and a child under the age of 10, all residents of New Castle County. Two individuals were fully vaccinated and two were unvaccinated. None of the individuals had a known history of travel.

“Case investigation and contact tracing to identify, inform and monitor anyone who was in close contact with these individuals is ongoing.,” Said Jen Brestel, a spokeswoman for the Delaware Division of Public Health.

Note the spikes that adorn the outer surface of the virus, which impart the look of a corona surrounding the virion, when viewed electron microscopically. In this view, the protein particles E, S, and M, also located on the outer surface of the particle, have all been labeled as well. A novel coronavirus, named Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), was identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China in 2019. The illness caused by this virus has been named coronavirus disease 2019 (COVID-19).

The Omicron variant has been classified as a Variant of Concern by both the World Health Organization and the Centers for Disease Control and Prevention (CDC). This variant was first reported in South Africa and has since been detected in more than 70 countries and at least 35 states, including Delaware, in the United States. Virus mutations are common. Preliminary data suggests the Omicron variant may spread more easily and quickly than previous variant strains of the virus.

According to a news release, The Delaware Public Health Laboratory and other laboratories regularly monitor for the presence of COVID-19 variants, including 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.

“With cases of the Omicron variant detected in our surrounding states, it was only a matter of time until we detected this variant in Delaware,” said DPH Director Dr. Karyl Rattay. “We are closely watching the science around this new variant. While it is encouraging that most individuals infected with this strain have reported minor symptoms, we still have a lot more to learn about Omicron. Therefore, we need to do what we know works to combat all strains of COVID-19: get vaccinated, get tested when appropriate, wear a mask in indoor public settings, socially distance from others and wash your hands regularly.”

Dr. Rattay said boosters may play a significant role in fighting the variant. Early results from both Pfizer and Moderna are pointing to booster doses being much more effective against the Omicron variant than having two doses alone. However, Pfizer is showing up to 70% effectiveness against serious illness leading to hospitalization after just two doses of the vaccine.

DPH has seen a significant rise in new positive cases over the past month, indicating a winter surge. Delta remains the dominant strain circulating in Delaware and the United States.

Vaccines remain the most critical tool to protect us against severe disease.”

Delawareans who are fully vaccinated have significant protection from COVID-19 infection, serious illness and death. Delawareans who are 5 years and older who have not received the vaccine should do so as soon as possible. This is especially important for the youngest eligible Delawareans, as they currently have the highest COVID-19 case rates. Visit for a list of vaccine locations.

DPH also encourages those who have been vaccinated with at least one dose to complete the full vaccination series and everyone 16 and older should receive a booster dose when eligible. Boosters increase the strength of your antibody response to protect you from the virus, and many of its mutations. All adults who completed a primary vaccination series with an mRNA vaccine at least six months ago and those who received a Johnson & Johnson shot at least two months ago are eligible for a booster.
