U.S. Reports Cases of New COVID Variant NB.1.8.1 Behind Surge in China
- The COVID-19 variant NB.1.8.1, which has contributed to a significant increase in cases in China and other parts of Asia, has been identified in several U.S. States and among international travelers at airports starting in late March 2025.
- The variant spread follows a large increase in COVID-19 cases in China and Asia, with reports from health authorities noting rises in hospitalizations and emergency visits amid ongoing virus evolution.
- U.S. CDC’s airport screening, supported by Ginkgo Bioworks, identified NB.1.8.1 cases from travelers arriving between April 22 and May 12 from nine countries including China, Japan, South Korea, and several in Europe.
- Officials say NB.1.8.1 may be more transmissible due to enhanced binding to human cells but does not show greater immune evasion or increased severity, with vaccines still expected to offer protection.
- Health agencies continue monitoring NB.1.8.1 amid low U.S. COVID-19 rates, preparing for vaccine updates while emphasizing caution as the variant drives rises in Asia but has not caused major U.S. Case surges.
