As the number of COVID-19 cases continues to fall in the Naperville area, public health officials continue to warn residents not to let down their guard as the Illinois economy slowly reopens.

Figures published on the Naperville coronavirus dashboard Tuesday show the number of active COVID-19 cases in the city hit 48 on Sunday, the lowest point since April 1, when 47 active cases were reported. At its peak, 162 active cases were reported May 24.

DuPage County’s rolling seven-day average of cases has been decreasing since May 27, said Karen Ayala, executive director of the DuPage County Health Department.

The decrease means there is less virus and disease circulating in DuPage communities, and the number of severe outcomes is on the decline. “But it clearly also indicates that this virus is still circulating and spreading,” Ayala said.
