Timeline of the COVID-19 pandemic in Maryland

The following is a timeline of the COVID-19 pandemic in Maryland.

January
In late January 2020, Maryland hospitals began travel screening for coronavirus when taking in new patients entering the emergency room. State health officials announced on January 30, 2020, that the first person tested in Maryland for the novel coronavirus did not have the virus. Fran Phillips, deputy state health secretary for public health services, stated that the risk for Maryland residents of contracting the virus remained low. Maryland medical facilities, educational institutions, and businesses disseminated guidance from the Centers for Disease Control and Prevention (CDC). Towson University stated that a professor would not return to classes while a family member was tested.

The University of Maryland, College Park and Towson University suspended their study abroad programs in Italy after increases in CDC alert levels. Towson suspended upcoming travel to Japan but did not suspend its current programs.

February
As of February 29, five people in Maryland had been tested for coronavirus, with the first two testing negative.

March 1–5


On March 5, Governor Larry Hogan confirmed the first three cases of coronavirus in Montgomery County: one married couple in their 70s and an unrelated woman in her 50s. All three patients were on the same river cruise on the Nile River in Egypt. Upon their return, one of the patients traveled to suburban Philadelphia, Pennsylvania, meeting with students. This prompted the Pennsylvania Department of Health and Central Bucks School District to temporarily close three schools in that district to undergo cleaning. Another patient visited The Village at Rockville retirement community for an event that had between 70 and 100 people. Attendees of the event were told to monitor their temperature and call their physician or the Maryland Emergency Management Agency if they began to exhibit symptoms. All three patients had fully recovered by March 12. Hogan declared a state of emergency after announcing the state's first positive tests.

Salisbury University suspended their study abroad programs in Italy and South Korea on March 5.

On March 12, Karen Salmon, Maryland's Superintendent of Schools, announced that all public schools would be closed for two weeks beginning March 16. Hogan raised the state's emergency activation system to activate the Maryland National Guard and banned gatherings of more than 250 people. Hogan suspended visits to state prisons and stipulated hospitals to implement policies to limit visitors.

Due to "sharply reduced" ridership, the Maryland Transit Administration (MTA) announced that all three MARC commuter rail lines would operate on a modified version of the "R" schedule, causing fewer trains to run throughout the day, beginning on March 17. On the Penn Line, four additional trains not listed on the "R" schedule operate (403, 502, 453, and 452), as does the Brunswick Line (872, 875, and 877), with only the Camden Line operating "R" schedule services as published. At that time, the MTA did not announce how long the "R" schedule would be in effect for.

MARC commuter trains were already in a special "R" schedule as announced on March 16.

Prior to the Worcester County Health Department announcing the second case, the Bundles of Joy University daycare facility in Berlin sent a message to all parents stating that the family member of a child enrolled at the Berlin location tested positive. In response to this, the daycare closed early on March 19 and will reopen on March 30 following quarantine.

Governor Hogan's March 23 order did not define construction businesses as being "non-essential". On March 28, The Washington Post reported on March 28 that the District of Columbia, Maryland and Virginia had designated construction as "essential", along with hospitals, grocery stores, banks and several other types of businesses. The Post reported that each of these jurisdictions had allowed private construction, including home building and commercial developments, to continue.

The Post reported that a spokesman for Hogan had stated that the Governor had classified construction as "essential in alignment with federal guidelines". However, the Post reported that several states, including Pennsylvania and Vermont, had suspended or prohibited all construction work (except for emergencies) as unnecessary during a public health crisis. The Post further reported that the State of Washington's transportation department had suspended work on nearly all of its projects and that Washington's governor had clarified his stay-at-home order to state that commercial and residential construction were generally prohibited "because construction is not considered to be an essential activity."

Governor Hogan's March 23 order basis its definition of "non-essential" on the United States Department of Homeland Security's March 28 guidance on essential critical infrastructure. That guidance lists as "essential" the construction of residential/shelter facilities and services (see "essential services"), energy-related facilities, communications and information technology, public works including the construction of critical or strategic infrastructure and infrastructure that is temporarily required to support COVID-19 response, is for certain other types of community- or government-based operations or is otherwise critical, strategic, or essential. The guidance does not contain any such listings for other types of construction.

Trader Joe's announced that their store in Elkridge, located in Howard County, was temporarily closing after an employee was either receiving treatment for a suspected case of coronavirus or had tested positive for the virus.
