The Centers for Disease Control and Prevention said that it now considers the Delta variant, which was first identified in India as a "variant of concern." Previously, the CDC had considered the mutated strain to be a "variant of interest." The new variant currently accounts for 10% of the cases in the United States.
The Delta variant is the sixth one that CDC considers a variant of concern, joining strains identified in the United Kingdom, South Africa, California, Japan, and Brazil.
The new variant could become the dominant strain in the United States by the fall and could spread amongst people who are not fully vaccinated.
