The head of the U.S. Centers for Disease Control and Prevention (CDC) said the “Delta” variant of COVID-19 could become the most common strain of the virus in the United States.

“It’s more transmissible than the Alpha variant, or the UK variant, that we have here,” Dr. Rochelle Walensky told ABC News last week. “We saw that quickly become the dominant strain in a period of one or two months, and I anticipate that is going to be what happens with the Delta strain here.”
