August 4, 2021
PHOENIX – After a brief period of decline, COVID-19 cases are back on the rise in the United States and experts say the delta variant, now deemed to be as contagious as the chickenpox, is to blame.
Delta, the name for the variant officially known as B.1.617.2, is a mutation of the original coronavirus strain. Originating in India, the World Health Organization called delta the “fastest and the fittest” in regard to its rapid spread.
As a result, new cases of COVID-19 have skyrocketed: Nationally, new cases jumped from an average of 14,438 a day in the first week of June to 72,493 per day in the last week of July, according to the Centers for Disease Control and Prevention, while in Arizona, cases rose from an average 425 a day to 1,595 a day in the same period, according to the Arizona Department of Health Services.
