June 20, 2025- The COVID-19 variant that may be driving a recent rise in cases in some parts of the world has earned a new nickname: “razor blade throat” COVID, according to AP News. That’s because the variant — NB.1.8.1. or “Nimbus” — may cause painful sore throats. The symptom has been identified by doctors in the United Kingdom, India and elsewhere, according to media outlets in those countries.
The rise in cases late last month is primarily in eastern Mediterranean, Southeast Asia and western Pacific regions, the World Health Organization said May 28. The new variant had reached nearly 11% of sequenced samples reported globally in mid-May. Airport screening in the United States detected the new variant in travelers arriving from those regions to destinations in California, Washington state, Virginia and New York, according to AP News.
