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.

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.

Wicomico County Executive Bob Culver issued a Declaration of Emergency, which was ordered to take effect beginning on March 23 at 8:00am local time.

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

He traveled out of the country and was recovering at home in quarantine. The second case involved a man in his 30s in Worcester County, who is also recovering at home. 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. The Worcester County Health Department could not confirm if the man in the second case and the man whose child was at the Bundles of Joy daycare facility are the same person.

On March 23, Governor Hogan ordered all non-essential businesses in the state to close effective at 5:00pm Monday to prevent further spread of COVID-19. He also announced initiatives to provide relief to small businesses and employees.

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.

March 24

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. The store was being closed to be cleaned and sanitized, though the company did not announce for how long the closure would be in effect.

Following Governor Hogan's order issued on March 23, the Baltimore County Public Library revised its plans and announced that instead of reopening after a two-week closure, all branches would remain closed until further notice.

April

April 1 
On April 1, Maryland announced 13 coronavirus deaths, all involving people age 60 or older; the most in one day yet from the virus. These deaths brought the state's COVID-19 death toll to 31, while its total number of cases neared 2,000, a 20% day-to-day increase. Four other assisted care facilities in the state had infections of at least 18 persons following the nearly 80 people who contracted the virus at Pleasant View Nursing Home in Mount Airy, where five subsequently died.

Until this order, licensed healthcare professionals were only permitted to deliver services via audio-only platforms to patients.

"Among the counties, Baltimore County had the highest number of overall unemployment claims, with 13,352 reported claims, according to the department. In Baltimore City, 8,685 residents filed for unemployment benefits. [...] Statewide, about 20 people per 1,000 filed for unemployment in March [2020]."
