Interactive maps and graphs tracking COVID-19, including Omicron, and other emerging variants are updated daily.
Aegis Sciences Corporation and Walgreens COVID-19 diagnostic testing and whole genome sequencing contains ~15% of all COVID-19 results in the United States. The combination of diagnostic testing, genome sequencing, and patient information produces valuable epidemiologic insights.Article describes an early indicator of the Omicron variant.
With the emergence of Omicron in early December, we developed a proxy method for early detection of the B.1.1.529, BA.1, and BA.1.1 lineages by analysis of S gene target performance in the Thermo Fisher TaqPath COVID-19 RT-PCR assay. S Gene Target Failure (SGTF) and reduced S Gene Target Performance (SGTP) were validated and have been used for over 8 weeks to monitor the spread of Omicron across the United States.
The Omicron BA.2 lineage was detected in early January in the United States. We have demonstrated that BA.2 does not have SGTF or SGTP. To continue real-time surveillance of Omicron as it remains the predominant circulating COVID-19 variant, we established an updated algorithm using the inverse of SGTF & SGTP, adjusted for the 3 day average of Delta and other variants, to track presumed BA.2 cases. Using the updated proxy method for early Omicron detection, we are capable of near real-time tracking of the most recent COVID-19 variants.
Notes from the Walgreens/Aegis Research Team
3/22/22 - ALERT: According to Walgreens COVID-19 Index, BA.2 is now the dominant sub-variant in the United States at 51.1% of new cases.
2/23/22 - ALERT: The BA.2 Omicron sub-variant has been spreading across the United States and Puerto Rico since its initial detection in early January 2022. Laboratory findings demonstrate that BA.2 does not display SGTP or SGTF as seen in the original Omicron. An updated algorithm using the inverse of SGTP & SGTF, adjusted for the 3-day average of Delta and other variants, has been validated to track presumed BA.2 cases. This innovative approach developed by the Walgreens/Aegis research team allows for near real-time tracking of the most recent COVID-19 variants.
2/22/22 - ALERT: The ‘Omicron Sub-Variant Trend’ graph and ‘Top COVID-19 Variants’ table are modified from a 7-day to a 3-day moving average to calculate variant proportions. This will increase sensitivity and timeliness of surveilling the prevalence of COVID-19 variants. Note: There will be a baseline shift to the data behind these variant trends.
2/21/22 - ALERT: The COVID-19 Index has added a page, Notes from the Walgreens/Aegis Research Team, to provide relevant up-to-date information on Index development and emerging data trends.

Over 300,000 Next-Generation Sequencing Performed
Aegis TAT is measured from the time samples are logged into our laboratory tracking system until test reports are released. It does not include transit time to lab. Aegis works with all of its collection partners to maximize the use of overnight shipping to its lab after collection. Shipping delays and weekend shipping schedules may impact the length of time between the collection event and the final Aegis report.
Please check the patient portal for the latest updates: patientportal.aegislabs.com. When the sample has been received in the laboratory and testing is underway, the portal will display that the sample has been received and testing is in progress. Results will be available in the portal as soon as testing is complete. You will also receive an email with your results as soon as your test results are released.
12/21/21 - In response to the ongoing COVID-19 pandemic, Aegis Sciences Corporation and Walgreens have collaborated to make real-time reverse transcriptase polymerase chain reaction (RT-PCR) testing readily available at more than 5,200 of the over 7,200 Walgreens locations that provide COVID-19 testing. As the virus that causes COVID-19 continues to mutate, both organizations have worked diligently to closely surveil the spread of the Omicron variant. Due to Aegis’ utilization of the ThermoFisher TaqPath™ COVID-19 Combo Kit for RT-PCR testing, we have been able to quickly monitor expected Omicron spread through identification of S gene target failure in COVID specimens, a phenomenon caused by the Omicron variant. Ongoing review of positive results with S gene target failure has demonstrated that nearly 30% of all positive results from specimens collected across the nation in recent days are likely Omicron, and spread of this variant is occurring at a significantly greater rate in some portions of the country.

1/20/21 - Last week, a review of published information comparing the effectiveness of saliva and nasopharyngeal samples in detection of SARS-CoV-2, the virus which causes COVID-19, was published in JAMA Internal Medicine, one of the most highly regarded scientific publications. After completing a thorough evaluation of all studies comparing the aforementioned specimen types, the authors concluded that saliva samples may not only allow for simpler and more comfortable specimen collection, but that they also offer comparable sensitivity and specificity in testing.

On April 14th, Centers for Medicare and Medicaid Services (CMS) announced new procedure codes and associated pricing for COVID-19 testing performed utilizing high-throughput technologies capable of processing large volumes of COVID-19 tests rapidly. CMS took this action in light of the high cost of resources, required investment, and advanced technical requirements associated with utilizing high-throughput technologies. All of Aegis’s COVID-19 tests are performed utilizing advanced high-throughput platforms. Aegis will continue to align with the floor pricing established by CMS, which is $100 for Aegis’s test, and accept that amount as payment for its COVID-19 testing.
