Fast-spreading Covid variant PJ.2.1: What Indians need to know

The World Health Organization (WHO) has designated a new COVID-19 variant, B.1.621 or 'PJ.2.1', as a 'variant under monitoring'.

While it has been detected in several countries, including India, its prevalence and potential impact are still being assessed.

PJ.2.1 has mutations similar to those in the Delta variant, which could make it more transmissible and potentially resistant to vaccines.

However, more data is needed to understand its characteristics and how it may affect the pandemic.
