New COVID Variant NB.1.8.1 Fuels Surge in China, Detected in US
The CDC’s airport screening program has detected the COVID-19 NB.1.8.1 variant in travelers from multiple countries, with cases also reported in several US states. This variant, currently dominant in China and rising in parts of Asia, has prompted increased COVID-19 cases and hospitalizations in some regions, although evidence of increased severity is lacking. Preliminary data suggests NB.1.8.1 may be more transmissible. The FDA’s vaccine advisory committee discussed updating COVID-19 vaccines for the fall and winter, considering that a new vaccine targeting the LP.8.1 variant could offer broader protection, including against NB.1.8.1.
