A NEW “DOUBLE MUTANT” strain of the coronavirus has been discovered in San Francisco, marking the first time the variant, thought to be behind a surge of cases in India, has been identified in the United States.
The mutation is referred to as a “double mutant” because it carries two mutations that help the virus attach to cells, The San Francisco Chronicle reported.
The Stanford Clinical Virology Lab identified and confirmed one case of the variant that originated in India.
