New COVID-19 cases plummet to lowest levels since last June

New coronavirus cases across the United States have tumbled to rates not seen in more than 11 months, sparking optimism that vaccination campaigns are stemming both severe COVID-19 cases and the spread of the virus.

As the seven-day average for new cases dropped below 30,000 per day this week, Rochelle Walensky, the director of the Centers for Disease Control and Prevention, pointed out cases have not been this low since June 18, 2020. The average number of deaths over the last seven days also dropped to 552 — a rate not seen since July last year. It's a dramatic drop since the pandemic hit a devastating crescendo in January. "As each week passes and as we continue to see progress, these data give me hope," Walensky said Friday at a news conference. Health experts credit an efficient rollout of vaccines for the turnaround. More than 60% of people over 18 have received at least one shot, and almost half are fully vaccinated, according to the CDC. But demand for vaccines has dropped across much of the country. President Joe Biden's administration is trying to convince other Americans to sign up for shots, using an upbeat message that vaccines offer a return to normal life.
