New COVID subvariant spreads in California, causes severe sore throat

A new, highly contagious COVID-19 subvariant, nicknamed "Nimbus," is spreading in California, raising concerns due to its association with severe "razor blade throat" symptoms. The Nimbus subvariant, NB.1.8.1, is becoming increasingly dominant, with projections suggesting it comprises over half of circulating virus in California. Wastewater analysis and test positivity rates are also showing increases, indicating rising COVID-19 activity. This rise in cases coincides with the Trump administration's moves on vaccine policy, which some experts fear will make vaccines harder to access. Health officials are expressing concerns about the potential impact on vaccine recommendations and coverage.
