WHO classifies triple-mutant Covid variant from India as global health risk

Read Time: 3 minutes

A World Health Organization official said Monday it is reclassifying the highly contagious triple-mutant Covid variant spreading in India as a “variant of concern,” indicating that it’s become a global health threat.

Maria Van Kerkhove, the WHO’s technical lead for Covid-19, said the agency will provide more details in its weekly situation report on the pandemic Tuesday but added that the variant, known as B.1.617, has been found in preliminary studies to spread more easily than the original virus and there is some evidence it may able to evade some of the protections provided by vaccines. The shots, however, are still considered effective.

“And as such we are classifying this as a variant of concern at the global level,” she said during a press conference. “Even though there is increased transmissibility demonstrated by some preliminary studies, we need much more information about this virus variant in this lineage in all of the sub lineages, so we need more sequencing, targeted sequencing to be done.”WATCH NOWVIDEO02:56Doctors on digital front lines help fight India’s Covid surge

The WHO said last week it was closely following at least 10 coronavirus variants across the world, including the B.1.617. The variant was previously labeled a “variant of interest” as more studies were needed to completely understand its significance, Van Kerkhove said.

“What it means for anybody at home is any of the SARS-CoV-2 viruses circulating can infect you and spread and everything in that sense is of concern,” she said Monday. “So, all of us at home, no matter where we live, no matter what virus is circulating, we need to make sure that we take all of the measures at hand to prevent ourselves from getting sick.”

A variant can be labeled as “of concern” if it has been shown to be more contagious, more deadly or more resistant to current vaccines and treatments, according to the WHO.

The group issued a clarification Monday to their earlier remarks, saying that current data shows the existing Covid-19 vaccines “remain effective at preventing disease and death in people infected with this variant.”

The international organization has already designated three other variants with the classification: B.1.1.7, which was first detected in the U.K. and is the most prevalent variant currently circulating throughout the U.S.; B.1.351, first detected in South Africa, and the P.1 variant, first detected in Brazil.
