- Experts state that despite its rapid spread, the Nimbus variant does not appear to be more severe than previous strains.
- The variant's quick transmissibility is attributed to genetic mutations that allow it to bind easily to human cells.
- The World Health Organization has designated Nimbus as a "variant under monitoring" and considers the global public health risk to be low, with current vaccines expected to remain effective.
