The delta variant of the coronavirus now accounts for 83% of new cases in the U.S., according to the Centers for Disease Control and Prevention. 

During the week of July 3, the variant accounted for 50% of new cases.  “The best way to prevent the spread of COVID-19 variants is to prevent the spread of disease, and vaccination is the most powerful tool we have,” Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention, said during a U.S. Senate hearing Tuesday.  The delta variant, which was first detected in India, reportedly spreads more easily than other iterations of the COVID-19 virus.
