The percentage of Americans who should wear a mask indoors in public is decreasing, according to data from the Centers for Disease Control and Prevention.

According to the CDC’s COVID-19 community levels, almost 34% of the population should hide indoors. More than 44% of the United States should consider masking in public spaces based on their risk of severe COVID-19.

The percentage is a slight decrease from last week, when levels showed 82% of Americans should hide or consider the measure. The previous week, the number was 85%.

The falling percentages come as new COVID-19 infections and hospitalizations also fall, suggesting that the latest wave of coronavirus in the United States peaked. The daily average of new coronavirus cases has fallen below 100,000 for the first time in about two months.

Meanwhile, CDC Director Rochelle Walensky this week recognized that the agency has failed to meet expectations during the COVID-19 pandemic.

“For 75 years, the CDC and public health have been preparing for COVID-19, and in our big moment, our performance has not reliably met expectations,” Walensky said in a statement. “My goal is a new action-oriented public health culture at CDC that emphasizes accountability, collaboration, communication, and timeliness.”

The agency announced a series of changes, including efforts to produce scientific findings and data more quickly as well as to produce policies that are easier to understand.
