"COVID-19 may have faded from news headlines, but it hasn’t gone away – or
stopped evolving. The World Health Organization (WHO) currently lists six
‘variants under monitoring’ — meaning they may require prioritised attention
and tracking by health authorities due to their increased prevalence and
potential public health implications.

One of them is NB.1.8.1, unofficially nicknamed “Nimbus” by the group of
researchers and citizen scientists who’ve proposed previous monikers like
Kraken, Centaurus and Eris for variants they thought people would be talking
about.

Another variant raising concern among virus spotters – though not currently
designated for monitoring by the WHO — is XFG, informally nicknamed “Stratus”.

Here’s what we know about these two variants so far..."
