Double Mutant Covid Variant Detected in 17 Other Countries

WHO considers India’s double mutant Covid variant a 'variant of interest'.

As recorded till April 27, India's double mutant Covid variant had been detected in over 1,200 sequences uploaded on GISAID from at least 17 countries, according to WHO update.

The double mutant Covid variant -- called B1617 -- is said to be fuelling India's second wave of Covid-19, which is deadlier than the previous wave. The new variant contains mutations from two separate virus variants, namely E484Q and L452R. The E484Q mutation is also found in both UK and South African variants, the L452R mutation in the California strain. According to experts, these two mutations appear to make the new variant more infectious as well as enable it to easily surpass immune defences. The double mutant Covid variant was first detected in India on December 1, 2020. Now, it has spread to at least 17 countries, the World Health Organization (WHO) said in its weekly epidemiological update on the pandemic.

As recorded till April 27, the B1617 variant had been detected in over 1,200 sequences uploaded on the open-access database GISAID (the Global Initiative on Sharing Avian Influenza Data) from at least 17 countries. Most sequences were uploaded from India, the UK, US and Singapore, the global health agency said on Tuesday.

According to the WHO update, the B1617 variant has a higher growth rate than other circulating variants in India, suggesting higher transmissibility rate. Apart from this new variant, the organisation underscored challenges around the implementation and adherence to public health and social measures and social gatherings as other drivers for the massive rise in Covid-19 cases in India.
