As the omicron variant races throughout North Carolina, the U.S. and the globe, it is becoming increasingly clear that our students, staff and faculty have neither the shared knowledge base nor institutional guidance needed to keep up.
In the days leading up to the launch of the spring 2022 semester, campus community members remain uncertain about the utility of rapid testing, the role of face masks in mitigating viral transmission and the true risks associated with in-person learning and engagement. We have been tasked with defending this institution’s historic ideals against a murky and previously unchartered reality.
Certainly, what we do know about the omicron variant — and its differences from previous strains of COVID-19, including the delta variant — justify our concerns.
As of Jan. 4, the Centers for Disease Control and Prevention reports that omicron accounts for more than 95 percent of all new COVID-19 cases in the U.S. That same day, more than 10,000 new COVID-19 cases and 3,000 total hospitalization cases were reported in North Carolina.
Studies have found that the omicron variant can infect and replicate within individuals at 70 times the pace of the delta variant, meaning that it is significantly more contagious and has a shorter incubation period between exposure and symptom onset.
Meanwhile, emerging small real-world studies are reporting that commonly used rapid tests may yield false-negative results, even when individuals are hosting high levels of the virus. Against a national testing shortage and President Joe Biden’s recent promise to deliver 500 million rapid tests throughout the nation starting in January, it is clear that we have not yet attained the promise of “a new normal.”
One may feel reassured by growing evidence that the omicron variant causes less severe lung disease than the delta variant, especially in individuals who have received a full COVID-19 vaccination series and booster shot. To date, the campus-wide vaccine attestation rate at UNC exceeds 90 percent, whereas 75 percent of all adults in Orange County and 57 percent of all adults in North Carolina are fully vaccinated.
Does this not render our campus safer than the surrounding community?
Perhaps, but vaccination alone does not completely halt the spread of infection, and vaccine efficacy is expected to gradually dwindle over time. Even mild omicron cases can manifest as cough, fatigue, nausea and nasal drip.
