Gov. John Carney is further limiting public gatherings under his State of Emergency declaration.
Public gatherings in Delaware are limited to 10 people through May 15 under the updated order.
Carney is also requiring essential businesses that remain open to follow specific directions to enforce social distancing on premises.
Those businesses cannot exceed 20 percent of fire capacity at any given time, and 10 percent during exclusive hours for high-risk populations, such as seniors.
Businesses must also mark six-foot spacing in check-out lines and lines outside, and designate staff to enforce the limits on the number of people coming in. Businesses must also discontinue self-serve food or product sampling.
In a statement, Gov. Carney said the state will take actions to enforce the restrictions if people and businesses do not voluntarily comply.
“Our goal is to save lives," he added. "This is a serious situation and we need everyone to cooperate. Don’t go out in public unnecessarily. If you need to go out, stay away from others. Wash your hands and follow basic hygiene guidance. We’ll get through this, but it’s going to take all of us.”
The revised order goes into effect 8 p.m. Thursday.
Gov. Carney's stay-at-home order went into effect March 24, closing all non-essential businesses. Businesses deemed essential, such as grocery stores and gas stations, remain open.
So far 11 Delawarens have died from COVID-19. The state reports a total of 368 total cases since March 11th.
