Maryland Gov. Larry Hogan on Monday took the unprecedented step of ordering millions of residents to shelter in place, imposing stricter controls on people’s movements as a means to further curb the spread of the coronavirus.

The stay-at-home order, which starts at 8 p.m. Monday, prohibits residents from making trips considered non-essential; Marylanders can still leave their homes for food and medical care. Under the order, those who violate the stay-at-home mandate could be charged with a misdemeanor, punishable by up to one year in prison or up to a $5,000 fine, or both.

“We are no longer asking or suggesting Marylanders to stay at home, we are directing them,” Hogan said.

Hogan said only essential businesses are allowed to remain open in Maryland and those that are essential must scale back their operations, limit staff and institute telework as much as possible. Grocery stores, pharmacies, pet stores, hardware stores, and banks have been declared essential and can remain open.

He added that no Maryland residents should travel out of state “unless such travel is absolutely necessary.” If residents do travel, they should self-quarantine for 14 days, he said.

Hogan’s order comes as the coronavirus has continued to spread across the Washington region and as more less stringent recommendations that people practice social distancing have been selectively observed. The D.C. region saw a jump in cases and coronavirus-related deaths over the weekend, bringing the regional case count to nearing 3,000. Maryland alone has reported 1,413 known coronavirus cases as of Monday morning and 15 related deaths.

Maryland now joins a growing list of jurisdictions nationwide, and internationally, whose residents have been ordered to stay at home, where they remain at a safe distance from others and limit the spread of the coronavirus.

As part of the executive order, Hogan also announced that drive-thru coronavirus testing sites will be available at vehicle test emission sites in Glen Burnie, Waldorf, and Belair. FedEx Field is open for testing as a partnership between the University of Maryland Medical System, the National Guard, and Prince George’s County’s Health Department.

“In two weeks time the DC-area could look like New York City and the Tri-State area,” Hogan said.

Maryland’s Deputy Health Director Fran Phillips says the test sites are only for “at-risk people with symptoms of the disease who will not be tested in emergency rooms or crowded physician offices.”

“The point of these test sites is to pull people away from those health care facilities, to spare the emergency rooms, and to allow for testing at an alternative site,” Phillips said.

The testing at these sites will only be made available for people with a health care provider order for a test or an appointment. The testing is for people over 65-years-old, health care workers, first responders, or senior citizens living in a facility.

Just hours after Hogan’s order, Virginia Gov. Ralph Northam announced a stay-at-home order for Virginia residents.

Virginians, like those in Maryland, will still be able to leave their homes for food, medical needs, banking, exercise and more, as long as they adhere to the state’s ban on gatherings larger than 10 people and as long as they maintain social distancing orders. Virginia parks will remain open, but the order limits access to the state’s beaches and prohibits swimming and sunbathing.

D.C. Mayor Muriel Bowser has yet to implement an official stay-at-home order. Bowser, Hogan and Northam are set to have a joint call Monday afternoon.
