CDC confirms cases of fast-spreading NB.1.8.1 variant linked to China outbreak
The U.S. Centers for Disease Control and Prevention (CDC) has detected multiple cases of a new COVID-19 variant, NB.1.8.1, among international travelers arriving at major American airports. The variant, part of the JN.1 lineage, has been driving a significant surge of infections in China and is now appearing in the U.S., raising concerns among health officials.
According to CBS News, the cases were identified through the CDC’s airport surveillance program at terminals in Washington state, California, New York, and Virginia. Genetic sequencing data from the Global Initiative on Sharing All Influenza Data (GISAID) indicate that most infections stem from travelers arriving from China, Japan, South Korea, and France between late April and mid-May.
Separately, cases have also emerged in Ohio, Rhode Island, and Hawaii outside of airport screening, suggesting possible community transmission.
Health officials monitor variant’s spread but downplay severity concerns
Early research suggests NB.1.8.1 may be more transmissible than other circulating variants but does not appear to cause more severe illness. Existing vaccines still provide protection, according to preliminary assessments.
In a statement, the CDC confirmed it is tracking the variant but noted that fewer than 20 sequenced cases have been recorded in the U.S. so far—below the threshold for inclusion on its public COVID-19 Data Tracker.
“We monitor all SARS-CoV-2 sequences, and if it increases in proportion, it will appear on the dashboard,” a CDC spokesperson told Fox News Digital.
Meanwhile, health authorities are also watching another emerging variant, XFC, which has shown recent growth domestically. The CDC warns that while the U.S. has settled into predictable biannual surges (summer and winter), the virus continues to evolve unpredictably.
U.S. COVID-19 deaths remain elevated despite declining infections
While cases are currently low, the CDC reports that COVID-19 continues to claim an average of 350 American lives per week—a significant toll, though far below the pandemic’s peak of nearly 26,000 weekly deaths in early 2021.
Experts attribute the persistent mortality rate to several factors:
- Low booster uptake
- Waning immunity in vaccinated individuals
- Delayed antiviral treatments among high-risk patients
As global surveillance continues, health officials urge vigilance but emphasize that existing tools—including updated vaccines and treatments—remain effective against current variants.
