The WHO said the variant’s “neutralizing antibodies” could increase its transmissibility or potentially increase its resistance. It was “associated with substantive rates of community transmission in multiple countries,” it said. In Peru, the Lambda strain now accounts for 82 percent of new infections. Meanwhile, Chile, Argentina, Brazil, Colombia, Ecuador, and Mexico, have all confirmed widespread cases of the variant.
