India has identified a new COVID-19 subvariant, NB.1.8.1, from a sample sequenced in April from Tamil Nadu. Experts suggest that while this variant may be more contagious, the symptoms observed are generally mild.

Key Takeaways:

• NB.1.8.1, derived from XDV.1.5.1, is designated a 'Variant Under Monitoring' by the WHO due to significant genetic changes.

• It potentially binds to human cells more effectively, increasing transmissibility, but symptoms (sore throat, cough, fever) remain mild and flu-like.

• Currently, there's no indication NB.1.8.1 causes more severe illness than previous strains.

• India's health authorities report the overall COVID-19 situation is under control, with robust surveillance in place.

While vigilance is advised, especially for those with co-morbidities, the current assessment indicates mild infections and no significant rise in hospitalizations.
