The new COVID-19 variant NB.1.8.1, known as Nimbus, is causing concern due to its subtle symptoms and high transmission rate. According to the World Health Organisation, recognising early signs and adopting preventive habits can reduce risk.

The COVID-19 Nimbus variant is on the rise in the U.S. as many report a painful symptom known as "razor blade throat." If you have a severe sore throat, it's important to rule out strep throat to avoid severe complications.
