How Hackensack Meridian Health Keeps Pace with COVID-19 Twists and Turns
May 25, 2022
Understanding the various COVID-19 variants is critical to treating patients with COVID. It is also a public health issue: Knowing how variants are evolving in the community can better inform health professionals about the potential effectiveness of therapies and vaccines.
That’s why Hackensack Meridian Health Center for Discovery and Innovation (CDI) runs a proactive virus variant surveillance team in partnership with Quest Diagnostics, which performs network-wide testing for the COVID-19 virus.
How COVID Surveillance Works
- Quest Diagnostics performs network-wide testing for the COVID-19 virus.
- Positive nasal swabs are sent to CDI for rapid molecular profiling of virus variants.
- The data is reported internally to our clinical community and also communicated to the New Jersey Department of Health.
- RNA sequencing is performed on about 10 percent of the viruses for quality control and evolution studies.
Over the past two years, the CDI COVID-19 virus response team has analyzed many thousands of viruses and is evaluating new virus-positive swabs collected on a weekly basis.
“The proactive stance allows Hackensack Meridian Health to quickly identify virus variants of concern and take a proactive clinical approach as needed,” says David Perlin, Ph.D., chief scientific officer at CDI.
For example, when an outbreak of a unique variant that was linked to immune escape appeared at one of Hackensack Meridian Health’s psychiatric facilities in New Jersey in 2020, the network quickly identified it and, through proper infection control, was able to squelch it before it could spread into the community.
“Ultimately, it’s easier to put out a small fire before it becomes a raging inferno,” Dr. Perlin says.
This proactive evaluation of infecting and circulating viruses is important to identify whether a variant is resistant to treatments, such as our frontline antibody cocktails.
“This process isn’t just important on the research end, but also on the clinical side,” Dr. Perlin says. “When a new variant is emerging, our hospitals need to know in order to prepare for it and the possible surge of patients that may follow.”
In addition, when the immune-escape Delta variant was first emerging in our region, virus variant analysis was instrumental in a clinical decision to change the first-line antibody cocktail to a more effective therapy. “Rapid clinical decision-making of this type requires a real-time interplay of scientists and clinicians to drive more effective patient management solutions,” Dr. Perlin says.
Identifying Future Variants
Hackensack Meridian Health continues to track COVID-19 variants in our hospitals in real time. “From the very beginning, this virus has evolved, and it continues to evolve on a daily basis,” Dr. Perlin says. “In terms of mutations, we can track the evolution, and what we’re concerned about are mutations that lead to higher transmissibility and higher infections, which then lead to more hospitalizations, morbidity and mortality.”
Most recently, the BA2 Omicron subvariant of COVID appeared at Hackensack Meridian Health on February 25, 2022 in a single sample. By the end of March 2022, this subvariant accounted for about 75 percent of new cases at our hospitals.
The hunt continues
“The rate of change of COVID has been astonishing over the past two years. It’s hard to say if it will continue to evolve month to month once we enter the endemic phase,” Dr. Perlin says. “We don’t know if that has been happening because there is so much of the virus out there, or it just reflects the nature of this particular virus?”
The Hunt for Variants
- CDI first identified the Delta variant in its patient population in May 2021.
- Delta was the dominant variant from June 2021 to November 2021.
- CDI first identified the Omicron variant in December 2021.
- Omicron BA.1 was the dominant variant from December 2021 to March 2022.
- CDI first identified the BA.2 Omicron subvariant in February 2022.
- CDI first identified the BA.2.12.1 subvariant in April 2022.

What Does Endemic Mean?
Straight out of a sci-fi thriller, we have lived through a COVID-state far longer than we all would have wanted. While the COVID-19 virus may not go away completely, the pandemic will eventually become endemic.
Why It’s A Bad Idea To ‘Just Get COVID’
Now that the highly contagious Omicron variant is widespread – and because people may experience milder symptoms with Omicron than with previous variants – you may be thinking, “should I just get COVID?”
