We are still not over the Delta variant, which has claimed hundreds of lives so far, spreading infections at an exponential rate, and yet another variant is here –  Lambda variant of SARS-CoV-2. On June 14, the World Health Organisation designated the Lambda variant, previously known as C.37, as the seventh “variant of interest”. The variant, which was first found in South American countries, has now been detected in over 25 countries but India, so far. Scientists fear that it is more contagious than COVID-19.

Is the Lambda variant a new discovery? No, the Lambda variant, according to the experts, has possibly been around since August 2020. The variant is believed to have caused at least 80% of the infections in Peru, where scientists believe it originated. Since then it had been largely concentrated in South American countries such as Ecuador and Argentina until recently. Though the number of cases found in other countries are miniscule, it sure has knocked at the doors of the larger population. France, Germany, UK, Italy, Australia and Israel have reported cases of the Lambda variant so far.

The variant’s spike protein, according to the WHO research, has at least seven significant mutations in contrast to the Delta variant, which has three. This, according to the research, could have implications such as increased transmissibility or even enhanced resistance to antibodies, created either naturally or through vaccination.

The WHO, however, said in a statement, “There is currently limited evidence on the full extent of the impact associated with these genomic changes, and further robust studies into the phenotype impacts are needed to better understand the impact on countermeasures, and to control the spread.”

‘Variant of Interest’

The Lambda variant has been designated as a “variant of interest” by the WHO. This category of mutation means the genetic changes are either known to or are predicted to affect transmissibility, severity, and even immune escape.  The WHO classifies seven mutations as “variants of interest”, of which four others are classified as “variants of concern”. The four ‘variants of concern’ are B.1.1.7, the variant first identified in Britain, will be known as Alpha and B.1.351, the variant first spotted in South Africa, will be Beta. P.1, the variant first detected in Brazil, will be Gamma and B.1.671.2, the so-called Indian variant, is Delta.

How will it impact India

Though the Lambda variant has still not reached India (at least has not been reported), the threat can’t be ruled out because the countries which are reporting a spike in the numbers due to this variant are operating regular flights to and from India. The countries like the UK, Israel and France are witnessing an increase in the number of Lambda cases. With the slow vaccination rate and very little information about the virus, India sure needs to be far more cautious than others.

What should India do?

 The deadly second wave has taught us to be ready and take aggressive counter-measure than taking a defensive approach. India needs to proactively go after variants like Lambda while continuing the vaccination drive before the next wave strikes.
