New Delhi: Dr. SK Sarin, the director of the Institute of Liver and Biliary Sciences, has said that though the Lambda variant is not present in India right now, it can come and that is the most worrying aspect of the present Covid-19 situation of the country. On the possibility of a third wave of the pandemic, he said that it can be fatal as there are chances that the virus will get the opportunity to spread because of the gathering of tourists as several hill stations of the country, Dr SK Sarin said to news agency ANI. On these most-discussed variants of the SARS-CoV-2, DrSarin said Delta, the variant which has been termed as the most transmissible by the World Health Organization is troublesome, Delta Plus, another mutation of Delta, is also there but cases have not been reported in large numbers. Lambda is most worrying, DrSarin said, adding that though it has not been reported in the country so far, it can come. While the 2nd wave of the Covid-19 pandemic was dominated by Delta Plus, which is still the variant behind maximum infections in the country, Delta Plus and Lambda are much in the discourse. Several states have reported Delta Plus cases but, according to scientific studies conducted so far, Delta Plus is found to be limited in some pockets of the states. Lambda, the variant first reported from Peru, has emerged as a new cause for concern as it has spread to around 30 countries. The health ministry of Malaysia has termed Lambda as a variant "deadlier than Delta".Lambda variant has not been found in India, but the Union health ministry has said that close monitoring of the global situation is going on. While Delta and Delta Plus have been classified as Variants of Concern, Lambda is a Variant of Interest, according to the World Health Organization.
