Staff reports | Recent data from the Medical University of South Carolina (MUSC) show the COVID-19 subvariant Omicron BA.2 and its fast-spreading offshoot, BA.2.12.1 are on the rise in the Palmetto State.
The lesser-known subvariant has caused a small surge in the Northeast United States, according to MUSC health experts, leading many to expect another surge coming sooner rather than later.
“As a scientist, we love to follow the data,” said MUSC’s molecular pathology lab director Julie Hirschhorn. “And we don’t really have any data to suggest that we’re not going to see another surge. So I am preparing as if we are going to see another surge. Hopefully, I am wrong.”
Hirschhorn’s team handles every COVID test that comes through MUSC. Those that come back positive are sequenced to determine their genetic makeup and categorized by variant. According to the team’s records, Omicron has made a big impact in their lab. It caused the biggest surge they’ve seen during the pandemic, and since its mid-January peak, it has continued to mutate.
What’s ahead remains unclear, but a recent 80% increase in weekly cases in Charleston is a factor to be considered, MUSC reports. But total cases still remain low, and severe cases are actually on a decline, a trend that many health-care providers hope continues.
