New COVID-19 Variant Nimbus Linked to 'Razor Blade' Sore Throats
A new COVID-19 variant called Nimbus (NB.1.8.1.) has been linked to a painful sore throat, earning the nickname 'razor blade throat.' While it has caused a rise in cases in parts of Asia and the Pacific, health experts say it is not more severe than other variants, and current vaccines remain effective. The WHO monitors the variant, but the overall public health risk is considered low.
